I notice that there are a lot of boards available with individual cell balancing (HCX-D139 Bestech,HCX-D120/103/108) @ different current/cell capacity from 8-80mA. However I am confused about how one determines/specifies balance current/cell? How does one specify this for 6 cells in series with a total capacity of 3100mA(3.1A)?
Does this depend on the load current?
I think these PCM boards are primarily designed for motor control, hence the very high current discharge capacities? I wrote to a few suppliers & they wanted to know the max.discharge current for the PCM.
Were they referring to to the maximum "load" current? Do I need to specify, say 1A or a little more for a flashlight/circuit board requiring 1 ampere?
Secondly, will these boards sink,say @ 100mA current?
