Auxiliary battery for semi truck
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.

Great value!
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.

Good quality batteries
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.

Do not recommend purchasing this product
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.
