  • Great value
Size: 2 PCS 12V300Ah(314Ah) 15.16×7.6×9.84 inch
Not the greatest batteries but functional and an amazing value. We'll see how long they last, but it was a great way to start out.

  • Defective battery and terrible customer support Defective battery and terrible customer support
Size: 12V300Ah(314Ah) 15.16×7.6×9.84 inch
Got this lithium battery around end of March 2026. Charged it up to 100%. Used briefly to test my 12v system. Battery’s charge dropped to 9v when it wasn’t used. System was off. No draw but battery lost charge. Having a very hard time getting the company to replace this defective battery. Will update review if company fixes the issue. ... show more

  • A good deal, excellent battery
Size: 12V 600AH 25.19×9.64×8.86 inch
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. ... show more
