I would like to DIY an external battery pack for my Evolve CGT (currently 10s5p SonyVT6), that I should be able to connect through the regular charging port.
The point is to increase the range for longer rides (just put box on board between legs, strap it and connect to charge port). It will be only used on long trips.
I am pretty novice to electronics, so I am looking for any helpful advices from you guys. My idea is to use 6S Lipo battery as power source, then a step-up converter to put 42V and 3/4Amps on output.
Sofar I have bought this converter and a few 5.5x2.1 / 5.5x2.5 connectors (dont know which one is correct for my Evolve). Connectors are on the way and the converter was delivered just today.
Still need to find some suitable case for the converter and battery (still not sure about the size of the battery, will get probably the cheapest per/Wh 6S battery from hobbyking).
So guys what are your thoughts about this?
FYI i am not able to put bigger battery inside the board and don´t want to cut or drill in that awesome carbon deck.
