Re: strange technical question Bottom Brackets

im crap at explaning tecnical stuff. but as will says i want to fit a bafang utra mount plat to a standard frame. the issue seems to be if i fit the plate and keep the crank possition (bottom bracket hole) in the same place, i either would have to drop the wheel size of extend the full back frame. s...

Tend to stick with 35e for smaller motors, though i do keep Sanyo and LG for some rebuilds i do for a company. Slightly bigger motors i switch to 30Q. And for really big motors Sony 30 or 35a. apart from a...

Re: What 18650 batteries for your battery pack?

i use several diffrent cells for diffrent motors, its always a trade of between cost mAh and draw.


depending on the P of the pack and budget, i tend to use samsung 35e for smaller motors, enough draw and lots of mAh without having a massive pack.

a 17.5ah softpack 10s5p is only 20 x 12 x 7cm

Re: Depleting Lithium Batteries

as said fully charging your battery and leaving it stood now and then isnt going to do it major harm. but constantly topping it up to full to let it stand, wont do it any good. will shorten its life. i have a luna smart and it has 80% for standing 90% for everyday use and 100% if you planing heavy u...
