    how many make 37v 10ah? I always thought wiring series adds the voltage, wiring parallel gives amperage, but wiring I guess you would call it bus bar? OK, so coming from LIPO world 10s means 10 cell, which basically means 3.7v x 10 or 37v Without peaking in the pack today can you tell me how...

    There has to be another option for a battery replacement other than $650. I'm good with a solder gun. I have learned a lot about LiPos from the RC world but I just need a little direction on sizing and what to purchase to fit either where the primary goes (my first choice) or a rear mounted...
