Sorry for the lack of detail. In that example, the charger was displaying 2.4v while I measured 13.1v at my battery, and at a different time the charger reading 14.6v no matter that voltage being measured at the battery I have ~400 total watts, a Chins 200 ah battery with built in BMS, and I...

For awhile it was a consistently high voltage reading, which worked. Now it randomly reading strange values, such as 2.4v, when my battery is at 13.1v, or reading 14.6v when the battery is near dead.

Renogy Rover 40 amp. Twice in the past month it has read the battery wrong, saying it was charged as the battery dropped to 0%. It also read a 0.8v higher reading than the actual battery reading, making it so I have to raise the charging values to levels that make me uncomfortable to even get...

Thanks sunshine, battery recovered just fine and appears to be operating normally. Will be monitoring to see if capacity had been affected

Thanks sunshine, that is reassuring. We'll see in the morning how it recovers.

My stupid renogy controller is acting up again, and my battery did not receive any charge for 24 hours (even though perfectly sunny outside). I have a 200ah CHINS battery with built-in BMS. After being drained, the battery reads 1.2v. it is currently on a charger per support instructions from...

Thanks for that info Mike. I was wondering why Chins had their voltage so much higher than most other specs I've seen. I'll adjust mine to 14.2v and see how it does

Thanks all for the info, it has been very helpful. My concerns are moot then

Thank you! That chart is very helpful. Another noob question, is there a danger to the battery if the controller is still in mppt mode while battery is at 99 or 100%? My understanding is that that is the job of the bms to shut off charging

Hi all, thanks for this forum and all of your knowledge. I just upgraded my deep cycle batteries to a Chins 200 amp hour LiFePo4 battery with bms and low temp shutoff. My question is that using the EE-BMS app, I see that the battery is at 99% SOC at 13.4 volts, but Chins advises setting charge...
