Editor Note: Affordable and powerful 18650 battery cells are the hottest thing in the DIY electric bike revolution (most well-known from their use in cordless tools). If you are looking for ready to buy 18650 packs with BMS go to Luna Cycle website.Bike builders everywhere are discovering that clustering many 18650s together are an
Here are four flat LFP pouch cells in series (4S). While 18650-format cells have a steel cylinder around them to provide compression and physical protection, pouch cells will need to have those added when building a pack. (notice the BMS harness has four black wires and one red). 3.2V X 4S = 12.8V nominal, for replacing a 12V lead-acid battery.
I build all my own Ebike packs and all my bikes are between 5-12kW of power. Heres my take: A smaller battery (18650), can fit in more spaces (more pack configuration options) and thermally dissipates heat better. Cost is a huge factor, with a Samsung 30Q (18650) costing about $4.50 per cell while the Samsung 40T is $7.50 per
