Size: 12V 300Ah 2 pack
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

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.

The first battery would not accept a charge, but when I contacted customer service, they promptly sent me a replacement battery which works perfectly. Very impressed with customer service.

On 12/28/26, I purchased (2) Lithium Batteries for my RV- Trailor My Yeagulch 12.8V 314AH lithium batteries will not hold a constant state of charge even without a working load... The batteries state of charge manuel is very confusing to say the least... 13.5- 100% 13.45- 99% 13.40-80% 13.30-70% 13.23-40% 13.18-30% 12.90-20% 12.80-10% 10.8- 1% I charged my batteries to 13.6 showing a 100% full charge but the very next day my batteries were at 13.30 at 70% with no working load according to the battery manuals percentage state of charge... I am having deep regrets with my recent purchase... I have reached out to yeagulch customer service... They have not responded to my recent dissatisfaction inquiry regarding my big disappointment with the batteries...

I used one of the 100 Ah 12.8 V models to build an off-grid solar power rig. I have not load tested to know if it truly hits the 100 Ah level, but it is easily exceeding my current needs. It will accept as much power as my charge controller and panels can dish out (about 30-35 amps) until it fills, so it charges quite well and quickly. I've been able to leave my inverter on 24/7 without any concern about the drain. They included two sets of post bolts in the package, so you have spares if you damage or drop one. Post bolt caps are also included. They appear to be either 8mm or 5/8", not sure, haven't checked which, but they fit nicely into the commonly-used ring terminals. I was able to connect it with a battery post fuse to a DC fuse block to connect it to my miscellaneous DC loads. Going to be adding more loads in the coming weeks, including lighting, computer networking equipment and two-way radios and may update this as the demands for after-hours power grows.

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.
