- 12V 300Ah (314Ah) LiFePO4 Lithium Battery, Built-in 200A BMS with 8000+ Deep Cycles Rechargeable 4019Wh Lithium Battery for RV Solar Marine Solar Panel Camping

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.

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.

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.

Bought two battery’s one charged and one would only go to 9.5 volts and it failed a load test . The seller gave me a run a round and Amazon helped me with contacting the seller about a full refund or replacing the bad battery. The said they would replace the faulty one after they ran me around asking the same questions over and I gave them answers and more running around Amazon help again ,so they sent me a return label and said the day I ship the battery back they would ship the same day a new one . It took them four days to ship back with more lies . I finaly got the new battery and it’s fine but what a hassle . Would not by from this seller

well packaged

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.

Bought there batteries about 9 months ago. They are amazing. One of them had an issue but the company did a great job to quickly ship me a replacement battery. They are a fantastic seller. Would highly recommend!

Works well. Charging rate seems to be on point with other batteries. I would recommend this product. Wait to see on longevity.

Great value for money, doesn’t have a heater for cold weather but that only costs 20$ to make one that fits underneath.

Received this battery with the side ripped open on the box, after opening the battery box the battery itself was in great shape. Charged the battery and ready to use. Great price on this battery.

I think this is the best upgrade. You could do for your boat.

First battery was faulty but the seller quickly replaced it with a new, later model battery. Excellent service!
