Wrandyr.
I was rather blunt and harsh writing about this EPLUS battB electronics.
sorry for this,
I understand you, you want to put such nice looking board to use.
but it does not change fact that that board controlled LiPolymer cells which caught fire.
of course balancing conditions of cells , LVC, HVC voltages are determined by software loaded on the processor you can see .
thank you for congratulations
yellow is a toggle switch , as you can see I have two throttles in paraller switched by this toggle switch.
why 2 throttles?
one for lower handlebars ,second for high riding position with bar ends.
