Hi guys,
I wanna ask about batteries.
what batteries did you use for your builds? 
Im thinking of making a 24v dc electric trike and I thought if I can make it lighter then it would not be slow and also saves energy.
what i thought is having pirated nokia handphone batteries hooked up till I get 24v.
but I dont know how much amps does the motor needs.
im going to buy the motor from aliekspress so I dont want to buy it from china to here and have it ruined by underpowered batteries :eek:
do you guys have recommendations?
the cheaper the better 
thanks.
