I'm thinking of developing a bosch range extender battery.
Using the original Bosch system and BMS, fooling the bike into thinking it's being set up as a normal dual battery with 2x a powerpack or powertube, but in reality it's a custom pack, cheaper, lighter, no need to carry a 2nd battery in a backpack or bag, no need to stop and swap batteries. Less wear on both batteries because the load is shared.
I'm considering using either 180Wh or 360Wh. 15A peak LG 21700 cells, 5Ah.
If you have a 500Wh battery and drive below 18mph/25kph, what size of range extender would you prefer?
The 180Wh could be under the saddle in t a small case or on the bottle mount points. The 360Wh could only be on the bottle mounts. The weight would be ca. 1kg for the 180Wh, double for the 360Wh. Easy to use on the frame battery models and rack models, a little more wiring needed for the powertubes.
