12V 330Ah LiFePO4 Lithium Battery with 4224Wh Energy, Built-in 200A BMS, Max 2560W Load Power, 10 Years Lifetime Up to 15000 Cycles, Perfect for RV Camping Solar Energy Storage Marine Trolling Motor

I purchased this battery to use as my auxiliary battery in my semi truck to power my 3000 watt inverter. I use the inverter to power my refrigerator and Starlink when we are parked for extended periods of time. So far it's working out really good. When I first bought I was ready to return it because there was no information on what app I needed to download. There seller messaged me right away and gave me instructions on downloading the app.

This battery was rated at 330ah. I tested it to 332ah after a 100% charge… so yes, it does what they say.It fits in the standard 2 bay Camco camper battery tray with room to spare.It is surprisingly shorter than my 200ah battery- don’t know how they pull that off, but they did!Absolutely love Bluetooth connectivity for information.

I used 3 of these 12 volt lithium in series batteries on a golf cart that originally had lead acid batteries. They were exactly as described and worked perfectly for my application.

We are extremely dissatisfied with both the product and the customer service we have received. Upon receiving the item, my husband attempted to charge it and immediately received an error message stating, “terminals are crossed.” I reached out to the seller for assistance, but unfortunately, the support provided has been inadequate.Despite scheduling two virtual meetings, the representatives failed to log in at the agreed times, instead appearing 3–4 hours late and then requesting to reschedule for 8:00 p.m. To date, the issue remains unresolved, which is especially disappointing given the cost of the product. Based on this experience, I cannot recommend purchasing this battery.

Great prices on batteries. Long life will save you money. Warranty is one of the best I’ve seen.

i can run my solix 10 and mega live in my boat for days on this. As well as running some smaller led lights. its extremely light as well.

Beware do NOT buy. Didn’t charge and when I tried to return. The shipping was $110. Seller will not respond.Typical dishonest business.

Lasts long on a charge recharges quickly
