12v 50ah Lithium Ion battery (Price), Rechargeable

(23 customer reviews)


This 12v 50ah lithium ion battery has an automatic built-in battery protection system (BMS), and the environmentally-friendly lithium iron phosphate battery (LiFePO4) can be charged more than 4000 times in deep cycle for longer cycle life. More than 20 times higher than lead-acid batteries (generally only 300-400 cycles of charging). Designed to be plug and play, suitable for any application where lead-acid, gel or agm batteries are currently used.

The 12v 50ah lithium ion battery adopts lightweight design and weighs only 6kg, which is much lighter than lead-acid batteries. Lithium batteries are easy to carry outdoors and place anywhere that lead-acid batteries cannot. Batteries can be used either in parallel or in series. It involves up to 4 identical batteries in series and 10 batteries in parallel.




Lithium-ion batteries are revolutionizing power solutions due to their long lifespan. Lithium-ion batteries last up to 10 times longer than conventional SLA (sealed lead-acid) batteries. The impressive durability of lithium-ion batteries also means that they require less maintenance than SLA batteries, significantly increasing the time between replacements and saving significant costs. With such great advantages and increasingly affordable prices, it’s no wonder that more and more consumers are turning to lithium-ion batteries for all their power solution needs.




Lithium-ion batteries are a more efficient and powerful alternative to SLA (sealed lead-acid) batteries, especially when it comes to charge times. Lithium-ion technology allows for fast charging, enabling the battery to charge to 80% in as little as 30 minutes. For heavy use, this is a big advantage: Not only do Li-Ion batteries take less time to recharge, but Li-Ion batteries tend to last longer than SLA batteries under the same usage scenarios. This makes them an excellent solution for powering robots, vehicles, and medical or industrial equipment that require frequent recharging or battery replacement.




Lithium-ion batteries offer great potential for weight savings compared to SLA batteries. By choosing this type of battery, you can save up to 70% in weight without sacrificing too much power. This makes lithium-ion batteries ideal for applications where weight is an important factor, such as portable electronics and small drones. Additionally, they offer higher discharge rates than SLA batteries, giving them an edge over competitors in terms of energy density. Lithium-ion batteries require less maintenance than SLA batteries and are generally easier to use. Because their shape is more consistent and predictable. With advances in technology making them cheaper and more efficient, it’s no wonder more and more people are turning to lithium-ion batteries.




Lithium-ion batteries are quickly becoming the first choice for people who need reliable power. That’s because they’re able to store and deliver an incredible 60 percent more energy than a similarly sized sealed lead-acid (SLA) battery. This means you can get longer run times between charge cycles while still achieving the same voltage level. Plus, they’re lightweight and compact, making them easier to transport than traditional SLA batteries. The end result is a higher performing battery with higher operating efficiency, longer cycle life and increased reliability – ideal for all types of applications.




Zero-maintenance batteries are perfect if you want a reliable, efficient power source with minimal maintenance. Once installed, these batteries require no maintenance, saving you time and money for many years to come. Also, when you compare zero-maintenance batteries to sealed lead-acid (SLA) batteries, you will see that zero-maintenance batteries provide superior performance in all conditions. Not only do they last longer, but they charge faster and are more reliable in inclement weather. Finally, due to advanced design features, zero-maintenance batteries require less space than SLA batteries. With its many benefits and lack of maintenance, it’s no surprise that zero-maintenance batteries are the first choice for many applications.




Lithium-ion battery technology has led the way in energy storage options and can now provide users with up to 100% usable capacity. That means more power can be stored in the same size battery without sacrificing safety or life expectancy. Lithium-ion battery technology uses materials such as lithium cobalt oxide to store large amounts of energy while maintaining its size and weight. It provides an efficient and cost-effective solution for long-term power storage needs, making it ideal for grid-scale applications and small projects. The ability to reach 100% usable capacity is a major advance in energy storage that will open up countless possibilities.




The ability to safely use lithium-ion batteries has improved greatly in recent years due to the introduction of built-in safety protections. This built-in safety protection ensures that lithium-ion batteries can be used safely and efficiently without fear of catastrophic failure. It protects batteries from extreme temperatures, overcharging and discharging, and short circuits. Additionally, it creates a thermal layer around the battery that quickly dissipates heat for efficient cooling. With these features, you know your Li-Ion battery is safe and will last longer than comparable batteries without this protection.




Lithium-ion batteries have never been easier and faster. This type of battery is increasingly preferred by businesses, institutions and organizations due to its durability and quick installation process. For example, instead of assembling bulky parts, connecting multiple cables, or waiting hours before fully installing a conventional battery, with a Li-ion battery you can simply plug and play. Given their ease of use and reliability, lithium-ion batteries are likely to become the new standard for energy storage applications in the near future.




Extended Warranty Buying a lithium-ion battery with an 8-year extended warranty gives you the peace of mind that you’re buying a battery that will last, even under normal wear and tear. Unlike other batteries that degrade quickly, lithium-ion batteries have a long lifespan provided they are cared for properly. Plus, if something goes wrong with the battery during the warranty period, you’re covered and don’t have to worry about buying a replacement battery. The 11-year extended warranty on the lithium-ion battery is a great option for those who need reliable power for everyday needs.

    Very pleased

    This battery is an upgrade for my grandchildren’s power wheels toy. Works great. I bought a connector wiring harness to convert to this battery ($10) which made the conversion easy. Was pleased and surprised to find that the battery arrived with a full charge so was able to use immediately.

    Works well to replace lead-acid batteries, but slightly larger

    I purchased three of these batteries to replace lead-acid batteries in a lawn mower battery pack. All terminals were placed in the same location as the lead-acid batteries, which made using the existing wiring a breeze. I used the charger that came with the lawn mower battery pack, and it charged each of these batteries to just over 13V, the same as it charged the old lead-acid batteries. They weight so much less; all told, with three of these batteries, the whole lawn mower battery pack weight decreased by over 10lbs.The only issue I had was that these batteries are slightly larger in width and depth than the lead-acid batteries. I had to shave off some of the bounding plastic tabs in order to get the batteries to fit comfortably inside the lawn mower battery shell. Once I did that, I could easily place them in the shell and still be able to open and close the shell with no more difficulty than when using the lead-acid batteries.

    Outstanding product, well made with clear instructions

    Replacement in my mobility cart. Has increased the distance I can go on one charge by at least double, seems to have more pep as well. Holds charge much longer than original wet cell batteries (1 year old).

    Trolling motor

    I googled kayak trolling motor battery and this was one of the batteries indicated. I can’t wait to test it since I usually use a couple motorcycle sized batteries for my kayak. Then, it snowed, again… I will update as soon as I can get on the water.

    Won’t last 15 minutes on a full charge

    Purchased these to replace SLA batteries on a mobility scooter. When fully charged they did not last 15 minutes of run time. I don’t think these batteries can handle the draw of device such as a mobility scooter, even though they advertise they will work.Unfortunately, these had a 30 day return window and it was 35 days before I figured out that the batteries were the reason the scooter would just stop, even though they showed to be fully charged. I put in a set of SLA batteries and scooter runs like a top. These should have some kind of warranty.

    Great multi use battery!

    I ditched the old, heavy lead acid battery in a DIY stereo build and WOAH is this thing light! It last 2x as long, hopefully it’ll hold up to the charge cycle ls to. *if you go from lead acid to lithium, you must buy a lithium charger!*

    Great energy density.

    Have only had this for a few weeks so cannot comment on the longevity but very happy with the charge /discharge performance. At first was concerned with the terminals and if they would be sturdy enough for many on off connections but they are strong enough. So far very happy with this item.

    Blows lead acid battery out of the water!

    I’ve only used this for a week so I can’t comment on long term longevity but holy cow! We had this in our scooter and our kids took turns riding it for an hour and a half and the battery still had full bars showing on the scooter’s display! Normally, with the old lead acid battery that came with the scooter it would have completely died within that time. Also, it weighs WAY less so the scooter seems to handle hold a little better, goes a little faster. Definitely recommend.

    Great Customer Service!

    I bought three batteries to build flounder-gigging rigs and they have been working great, they easily last all night and are very lightweight. I had a question about charging them and received a very detailed response, they definitely back their products.

    Great For Fish Finder

    I’ve been using this to power by Garmin Striker 9sv. When I go out the fish finder is usually powered on between 4 and 7 hours. On my charger, it gives a digital readout of estimates available charge and it’s usually sitting at 70%. I can see this lasting me a few trips. The best part about this is the weight. Compared to my trolling motor battery this thing is like a feather. I would highly recommend this battery to anyone looking to power any 12V fish finder.

    Don’t forget the wires !

    Batteries are a great replacement on our razor dirt bike , don’t forget the wiring you will need to replace the old … if you aren’t familiar with wiring I’d recommend a pre wired battery and not this. Batteries charge well stay charged for a while and can handle my 4 yr old taking it out on trails , def worth the money

    It arrived charged and functional

    Love how light compared to the acid lead batteries. I hope they last a lot longer. If they do, these are definitely worth the more dollars.

    Battery failed and stop holding charge right at about 6 months

    Product was advertised to last 2000+ recharges and I would guestimate that it only held about 12-14 recharges. I use it solely for my boat gps and nothing else. Initially it would last for approximately 3-4 fishing trips before needing to be recharged and for the last 2 months, it started only holding a charge for 1-2 trips. Last fishing trip that I made it lasted only about 4 hours and died. When I attempted to recharge, my charger gives me a defective battery signal and it will not hold a charge now.

    Battery is dead

    Charged battery one time. Battery seemed to work good. However now it’s dead with zero volts and won’t charge. Return window has past and can’t find any information on contacting manufacture.

    These would be a bargain at twice the cost.

    They are much lighter than I’d expected, the longevity is unbelievably good, and they’d be worth more than twice what they cost and still be a bargain. I use a mobility scooter and the difference is unbelievable. No loss if power up hill. And I go easily 2.5 to 3 times farther than the best lead acid batteries.

    Quick received still checking durability

    Good price, received early works in place of SLA. Checking endurance with current SLA charger, mat get LiFePO4-specific if needed. Worth consideration. rjs

    Gets the Job Done

    I got the, basically, 2 for 1 deal. So far, so good. Used them 3 times for about 5 hours at a time for my fish finder. No issues. Can’t beat the price. Will wait and see how durable they are.

    These are great!

    The batteries in my mobility scooter went dead. The manufacturer of the scooter wanted $160 for replacement. After looking at different options, I chose these. When the package came, I thought I’d made a mistake as the box didn’t weigh as much as one of the original lead acid batteries. I opened the box and there were indeed two batteries inside. After charging the batteries, I installed them and was very happy to see that they functioned flawlessly. Half the weight, less money… What more could you want?
