36 volt part kit available here ! https://www.ebay.com/itm/384804099883 Everything except for 3d printable parts and 18650 cells included ! This version of this bike battery is in final release - there may be a Version 2.0 out but not anytime in the foreseeable future. The 48 volt version of this e bike battery requires a 3d printer with a bed size of 287mm x 104mm x 25 mm tall. You probably will not be able to rotate it and print it 104mm x 25 x 287mm tall – It doesn't work that way , the sides will need a ton of support and making the sharp right 90 degree turn in midair will definitely fail. The 36 volt version of this e bike battery requires a 3d printer with a bed size of 233mm x 104mm x 25 mm tall. Rotating the print is also not recommended The 2 cell voltage booster pack is relatively small and can be printed on almost all 3d printers. It's size is 104mm x 86mm x 27mm . Rotating the print is also not recommended Note – Most 48v Chinese e bike controllers have 61 volt capacitors in them – this means at 61.1 volts they will most definitely break. Over - volting a Chinese 48 volt controller is only advisable 1 cell past 13s ( 13 cell in series ) for a total of 14s ( 14 cells in series ) .

I will have some part kits ready on eBay possibly in April 2022 ( I make about $1 off the parts , for those of you curious , the intended design of the parts kits is to keep those interested from having to buy quantities of 100's of parts when only 2 or 3 are needed, at $11 a parts kit I think your savings are about $39) Also keep an ear out for new bike clamps as we find a style to support your frame !
