At 3.55v (before getting properly balanced yesterday) I would trip... I had several cells at 3.587V readout (which is probably 3.537 V in reality).I always just calibrate them and add the safety margin on the OVP. There is no need to go to 3.65, or even 3.6 for that matter - so why not put it at 3.55.
So... If I calibrate the voltage, then yeah, why not set at 3.57V or so the OVP.
But if I do NOT calibrate the voltage, then margin on top of margin on top of margin I end up hitting OVP when the cells are barely 3.50Vdc in reality.
My question was specifically about FLOAT ("long" term) Voltage though. Not absorbtion or EQUALIZATION (shorter term) .
