Hi I have a slight problem. I need to get the capacity of different batteries (eg 18650, NiCads etc). I have a PROTEK EL300 Electronic load which I can not find too much info on it (also rebranded arrow 3711 and other makes). Tried to contact Protek to get there software but I have had no response. is there a way between my (ebay purchased) PROTEK EL300 and my Rigol DP832 to determine the battery capacity of different batteries?
