Features
- 12v Deep Cycle Battery: Lifepo4 battery 300ah have extended cycle life. 12v 300ah battery can withstand a high number of charge-discharge cycles, often exceeding 6000 cycles to 80% depth of discharge, which significantly outlasts traditional lead-acid batteries. 12V 300Ah LiFePO4 battery can be used in small trolling motor, which the power should not exceed 2KW.
- Used to replace lead acid battery: 300 amp hour lithium battery 12v offer a higher energy density compared to lead-acid batteries, but only have 1/3 the weight of the lead acid battery at the same capacity. This means 12v 300ah lifepo4 lithium battery can store more energy per unit of weight and volume, making them more efficient and space-saving for energy storage applications.
- Multi protection BMS: 12 volt 300ah battery is built in an enhanced BMS that provides protection against over charging and over discharging, low temperature charging, over current and short circuit. In addition, when the lifepo4 battery 12v voltage exceeds 14.1v, the BMS will activate automatic balancing to ensure that all 12v batteries at the same state of charge, which helps to improve the performance of the battery. Boasting robust safety features, you can use 12v lifepo4 battery reliably.
- Ideal for Outdoor Application: The 12 Volt 300ah lithium battery features IP65 waterproofing, allowing it to be used in extreme weather conditions. It is the perfect choice for RV, solar energy storage, industrial batteries, residential energy storage and power walls, marine applications, fishing, boating electronics, ice fishing, recreational vehicles, and off-grid living.
- Note and Customer Service: This 300 ah lifepo4 battery 12v is not suitable for starting gasoline engines. 12V 300AH LiFePO4 batteries are designed solely for energy storage. Do not use them for starting devices, golf carts, or jacks. Under Various Temp/Humidity Measurement Methods And Instruments, Voltage And Current May Deviate By 1% to 5%. Charge/Discharge Battery Once Every 6 Months To Prevent Damage From Disuse. If you have any questions about 12v 300ah lithium iron battery, please contact us.

I purchased this 2-pack of 12V LiFePO4 batteries and so far they have exceeded my expectations. Both batteries arrived well packaged, fully functional, and in perfect condition. The capacity is consistent, they hold voltage very well, and provide stable performance even after multiple charge and discharge cycles. I’m using them in a power system and they have worked flawlessly. They are noticeably lighter than traditional batteries and the LiFePO4 technology offers great efficiency and reliability. Getting two batteries in one package is a big plus for the price. Very satisfied with this purchase. I would definitely buy them again and highly recommend them to anyone looking for durable, safe, and high-quality batteries

In service 4 months now and NO issues I use these full time 24 7 and at this price point you can’t go wrong. Only time will tell the rest of the story.

Seems to be an excellent deal. I moved from 5 200AH batteries to 4 of these 600AH batteries. Packaging was excellent. Batteries had tome heft but were easily managable by one person. I was able to use the same battery cables as the previous batteries even though I removed one. These are a bit longer than the previous ones but still fit in the storage bay of my Class A motorhome. We have had a couple of short power outages this winter and I did not have to worry about losing power to the coach with the extra capacity these bring. They leveled up on charge quickly Without BlueTooth capability it's not possible to check indvidual batteries but my Victron system shows the proper capacity and the batteries recharge quickly after use.

Size: 12V 100AH 12.8×6.5×8.46 inch
I purchased a 100 ah Yeagulch LiFePO4 Lithium Battery in February 2026. It came roughly 40% charged. I put in on a Nico Genius 10 amp charger for the recommended period before attempting to use it. The first few times I used the battery were extremely low load exploratory exercises. I was shocked when the battery readout quickly went from fully charged to 20% in less than 2 hours with nothing more than a cell phone and and an Ipad USB connected. Neither device was below 30% capacity. So it was unreasonable that such low loads would drain nearly 80% of the 100 ah Yeagulch capacity. At first I believed it was something I was doing wrong either in the way I built my DIY box or I maybe had a bad amp reader. It was when I researched the issue more aggressively I first learned of the problem that some BMS units do not properly balance the cells inside their lithium batteries. In such cases the defective lithium batteries behave similarly to the one I purchased. Namely, they show fully charged on a charger's reading and on any amp reader present prior to adding any load. But as soon as one attaches a load, the defective lithium batteries begin depleting at shockingly fast rates well above what any attached load's draw down should produce. It took me until April 6th to figure learn about this possible defect with some BMS systems. But wait...There's more! Since I didn't discover the problem until after the return window had closed, apparently I will now have to eat the entire cost of purchasing this product that was defective from before day one. Now here's a real kicker! There is a fix for this defect in a lithium battery's BMS. It requires opening the case of the defective battery and adding a component called a 'balancing board.' But like many, I am a DIY amateur in the buildout and usage of DIY lithium power units. I can't imagine having to do such a repair to rescue a brand new lithium battery. Furthermore, opening the case will most certainly void any existing warranty on the product. So now, I'm left with three unpleasant options. Either I accept I now own a completely diminished product because I got taken to the cleaners on a bad purchase or I step into deeper water in the lithium battery repair world than someone like me should have to do or I pay someone whose more qualified to repair my still new but defective lithium battery. I know I'm not the only person in this position. If Amazon is allowing battery sellers to sell lithium battery products to their customers that are represented as complete and ready-to-use; but with significant hidden cell imbalance defects and under the umbrella of buyer-beware then here is what I recommend. Whenever you buy a battery from Amazon, have it tested immediately. If it even remotely appears to be sketchy or underperforming, return it pronto, without remorse and let others know about your experience. So far, this has been the worse purchase I have ever made through Amazon.

Great quality batteries! They shipped fast and arrived sooner than anticipated, which was awesome. I had a few questions and the seller answered quick and was super helpful. 10/10 service. Great value for the price! Batteries work as they should, no complaints.

Weighs roughly 60 Pounds. It works great. The Power is amazing and the quality is amazing. I’m running 200 Watts Solar with a small house fan and charging my phone. The size is a little bigger than I imagined but that’s my fault. I will be ordering at least one more 300 Amp battery. I’m definitely positive this will help achieve what I’m going to accomplish.
