Review on Renogy 12V 100Ah Lithium LiFePO4 Deep Cycle Battery With Built-In BMS And Over 4000 Cycles - Ideal For RV, Marine, And Off-Grid Systems With Maintenance-Free Operation And FCC/UL Certifications by Chad Gravely

Renogy gets a lot of hate. I researched extensively before I purchased this. I had many questions for techs about the build process and cells. Everything checks out. They were mostly easy to contact, if not they'd call back. I've been running mine for about six months with renogy solar panels and charger. Everything works great. As long as there's some sunshine I don't even think about it anymore. As far as tracking your voltage, avoid their Bluetooth system. It's crap. Get an Aili voltmeter and shunt for $40 to get an accurate read on your battery. ✌️
