I have a 2012 Stromer ST1, I assembled a new 36v 22A / h battery, 10S5P configuration, from 21700 batteries, 50 pieces fit, 21700 batteries are more reliable and stable, I modeled and printed the details on a 3D printer, plus I have a native battery 36v 14.5A / h, 12A/h remains in it after 10 years, now I can drive long distances.o_O Has anyone done something similar? share your experience and attach a photo :cool:

21700 batteries are more reliable and stable,

Very impressive work!

How did you manage the use of the 1to1energy battery for such a long time? Some users build their own 48V range extenders on the 27½" Stromer, but never heard from a self build 36V battery. May you estimate the overall costs (without time, tools and repair shop)?

The 21700 cell give you less wiring work. But energy density and cell chemistry are the same.

For me, the rigid fork was way too hard and the headlight nearly a joke.

1to1energy battery turned out to be very reliable, it cost about 500 euros to make a new 36v 22A/h battery. 21700 cells have no imbalance, they do not quickly lose their capacity.

Very interesting.
Could this be done to replace their 48V 983 wH battery?
Well into the future I hope……and hopefully by then the 21700 tech will be 20% of present cost😀
