combatwombat Posted January 1, 2016 Author Report Share Posted January 1, 2016 I have bought two batteries now and the board will drain both too low. Right now cell 1 - 1.9v, cell 2 - .96v, cell 3 - 1.98v. I have set the cell cutoff to 2.7 but the board seems to ignore this. Any help would be appreciated as I have no idea what is going on because it happened with two batteries. The batteries will work fine for a few days to weeks then drain way below. So now two batteries are garbage because the board or can i salvage them with a external charger? Link to comment Share on other sites More sharing options...
combatwombat Posted January 4, 2016 Author Report Share Posted January 4, 2016 had to wait for it to charge to 1.01 v at 0.015a current then perform usb recovery. Strange, when i set cell cutoff to 3.2 it worked with a check battery msg. My other battery is 0.00v on all 3 cells and seems not to charge at all.

combatwombat Posted January 5, 2016 Author Report Share Posted January 5, 2016 I believe for my lifepo4 battery or a bug in software I have to change the soft voltage cutoff and upload settings for it to work correctly. I want to try battery analyzer, as I am messing with the curve but afraid of frying something and the meter for lifepo4 is a crapshoot anyhow due to how the battery acts.

blueridgedog Posted January 5, 2016 Report Share Posted January 5, 2016 I do not have experience with lifepo4, but I am surprised that cell two is so much lower than the others. Link to comment Share on other sites More sharing options...
