hi
i need clarification
on benergy site i see 3 mesures for discharge . which one do we have to take into consideration? for example if a motor is rated 30amps how to determine the battery amps needed. so far i read that it is better to have 10amps more in the battery than the motor is asking to not stress the battery. so do we use the standard or the max discharge spec to establish calculation?
any comments advice welcomed. those cells are light 150g since external in plastic( i say to myself if i compress them no need to have aluminium casing maybe im wrong...).
but the spec have a big difference 1.4 vs 50amps. why?
Plus if you open the report testing they send me they dont show the same spec as seen on their site or below. this also i would like to understand if someone knows
is benergy recongnised as reliable?
