Re: XLD XunLiDa controller broken

the three most likely things are: -- "ignition" or "keyswitch" or "doorlock" wire from controller to battery broken somewhere (if it has one). this takes battery power to the lvps (see below) to "turn on" the controller brain. -- just a broken wire between controller and throttle -- the low voltage ...

Re: EASY/FAST/INEXPENSIVE way to connect pouch-cells together

if you look up some of the old a123 pouch cell threads, there are a number of methods tested and proposed, including variations on both of the ones posted in this thread so far.

should give you some data on what *not* to do, at least.

Re: ebike build questions (BBS02)

fwiw, that type of caliper brake is likely to only fit a fairly narrow rim and small tire (less than 30mm, probably 25-28mm), like on "racing bikes". . not sure if that is what you want, since your existing wheel / tire may be much larger than will fit in that brake.

Re: ebike build questions (BBS02)

a v-brake requires bosses on the frame tubes to mount the caliper arms. there are clamp-on bosses, meant for situations like yours where you want to add brakes the frame wasn't designed for. https://www.google.com/search?newwindow=1&q=clamp+on+v+brake+bosses https://www.google.com/search?q=clamp+on+...

Regarding fans, even though it wasn't the issue here, is that the bearing are designed to work in a certain orientation, horizontal or vertical. fwiw, those aren't usually bearings, they're just bushings, and are fairly equally crappy in any orientation. ;) (though if the bushing is loaded by the f...

Agreed, as on as the rider is monitoring the situation it works fine. I was thinking about my pack, with BMS and separate charging port. yes, with something like yours the whole system is limited by the rate at which the battery can accept charge. if it can only accept 100w of charge, then if the s...
