LOSSIGY 12V 200Ah Deep Cycle LiFePO4 Lithium Battery, Perfect for RV, Solar Systems, Marine, Built-in 100A BMS, 1280W Load Max Continuously

As mentioned knowing is key it's taken time and several days of phone calls to get the settings right thanks to signaturesolar.com for that. But been running 48hrs straight no issues. Be aware of your loads 100 amps is total pull before the bms shuts off so no matter what inverter you have be aware of your battery limits. But overall a good value great build quality and easy as pie to deal with. Set it and forget it. I love it.Update. Had 1 batteries bms go bad suspect the cold got to it. Loggisy was not happy but ended up replacing it now the system is operational. So far .15mwh no issues

It worked good until it didn't. It juat stopped working with no warning. They claim 5 year warranty but no one will respond to emails to warranty it

Put this in our RV that came with a 165 watt solar panel and it works great. Have boondocked for as long as 5 days and never went without power. Strong enough to go for a few days without sun. Even with our 12 voltfridge running day and night. Couldn't be happier so far.

This is a very good battery. The seller is the Best.

3 batteries went dead and the BMS on two batteries refused to wake up. I tried connecting the dead batteries in parallel to working batteries, connected to a 12v charger, and bought a $175 special LifePo charger and nothing worked. I contacted the supplier since the batteries were quite new and they stopped responding to my emails after trying them in parallel. I offered to ship them back for repair and no response.You should consider a different supplier and purchasing an extended warranty if there is any chance the batteries might go dead at any time in the next 10 years.Now I have to figure out how to dispose of $1100 in batteries with perfectly good lithium in them or figure out how to repair a sealed battery BMS.I’m not a happy customer.
