    Hi I have the 20 amp 100volt Epever charge controller. When it’s discharged and the sun is out it’s putting in over 15 amps and everything is fine. The voltage started at 15.25 and then slowly rose until around 16.5 which is when it starts acting weird and cuts out. It’s as though it can’t...

    Hey I built a 4s100p 270aH Lithium Ion Pack. I installed a Daly 4s35A 12V BMS and wired it up. It appeared to be working perfectly for about 6 weeks with daily use then the inverter kept randomly rebooting. I checked out the pack and found this... Top pack - near the positive - was 3.63V...
