Now about 20 hours and readings 3.46 and 3,47
Once they get above 3.45, it goes much faster.Now about 20 hours and readings 3.46 and 3,47
Yes your right. I got to 3.6 in another hour.
Now can you please tell me the best settings for my BMS?
Here is only a few default settings.
Overvoltage = 6.3v I set this.
under voltage = 2.5v
Pack over voltage = 14.6
Pack under voltage = 10v
Balance turn on voltage = 3.2v
Balance precision = 0.03v
Single full voltage = 3.6v
Single cut off voltage = 2.8v
Self discharge rate 0.2%
“lipo4” is a gibberish cross between lipo (lithium polymer) and LiFePO4 (lithium iron phosphate). Pretty different battery types!4 lipo4 280a
My guess would be that 280Ah cells (common) would be LiFePO4 but if OP really has a lipo BMS and lipo charger, it might explain some of these oddities.I would have thought the Lipo charger/balancer
This is gibberish.lipo4
The semantics are pretty irrelevant though.This is gibberish.
Yea, those hobby chargers are usually really good with charging cells within their range when proper battery type selected and using balance leads.The exact type of battery is important. When I saw 4.1 and BMS attached earlier, I started thinking there was a Lithium Ion BMS installed, which has higher parameters than a LiFePO4.
Sounds like it’s wired properly. And the balance leads are connected too?The BMS is 3 terminal B+, B-, C-,
3.67 did not damage the cell. At least nothing you’ll notice. Not a mere .02 volts.Individually top balancing my cells (without changing any settings) one cell ended up at 3.67, have I ruined it? Can I lower the voltage just slightly somehow and do a re-balance?
It's possible I may have let it charge a bit longer than the other cells at 3.4V. Talking minutes not hours.
