I recently finished my diy eboard. The first time I took it outside I did a 12km ride and it was fun! When I got home the battery drained and the board couldn’t get me forward anymore. When I checked the battery at home It still had 30% left in my battery. (According to an inbuild battery meter) I charged my board en the next day I did another round with a fully charged battery. The first km I got my regular 38km/h speed but after just 1km I couldn’t go faster than 15km/h now this keeps happening now and I really want to fix this, but I don’t know what it could be? Does someone experienced this?
My setup: 10s2p li-ion battery, Antispark switch, Flipsky Vesc (I did set it up with the software), Maytech 200KV motor.
