Considering 16S 48V DIY build

Hi UncleJerm,

I’m glad you’re happy with the Daly but unfortunately it’s just not up to the standard I expect from a device costing so much.

The CALB cells you used are very high quality and are definitely a reason your BMS isn’t working too hard to balance but if you check your cell voltages at full charge then you’ll see an imbalance. Anything below 95% SOC will show minimal voltage deviation due to the very flat discharge curve of LiFePO4.

If you’re not showing more than 20mV deviation at full SOC (cell voltages above 3.55V) with the Daly, then you have a very good battery indeed because it’s definitely not the Daly keeping things in check.

Cheers
Pat.
