This is a work in progress (which stagnated a bit since it is cold outside) 3p10s diy 18650 battery pack for a koowheel dm3 This will increase your range (Standard pack is 5500mAh, with proper samsung 30Q cells you'll go up to 9000mAh other hardware required: subd 2w2 (please mind sufficient current capacity 30~40A) M4 threaded rod + washers + nuts 10S BMS (small and simple will do) Fuses (if your not as brave as me ;-) ) nickel strip 0,2mmx8mm note: you'll have to get creative wiring the cells, i finished one but it is a pain since the pack layout is 3p10s and the housing is 5x6, so you'll have to create a few split-3-cell blocks, use sufficient thick (or layered) nickel strip, otherwise you'll end up with 18650 micro rockets, which won't end well I added a zipfile with solidworks files, if you prefer to remix ;-)
