Others may have recommendations for reliable Aliexpress vendors but personally I prefer to buy from nkon.nl No fakes, good prices.

I've bought motors from FietsUnie and been happy with them I see they have gears listed for the G320 here; https://www.fietsunie.nl/BAFANG-FM-G320.250.R-Nylon-tandwielen I don't know for sure, but I suspect the internals of the G320 are the same as the G310 / G311 as all the specs are...

The shop only appears to have the Kcap that comes prepopulated with 6x BCAP0310, wasn't there previously a board-only version for people supplying their own caps?

Different cells inside. LG MG1 vs Samsung 30Q. The latter are rated for higher current. Fewer modules implies higher current demand per module. Note that higher current is not universally better, cells are always a compromise between energy capacity, power (current), cycle life, cost, etc etc...

More info needed, it depends what you mean by high amps. What is the full spec of the bike and how big a pack are you willing to use? What kind of cycle life are you hoping to see? etc etc

PETG is great. Less ultimate strength than PLA but not brittle. The bit of ductility / flex makes it far more impact resistant so more useful in a lot of utilitarian applications. Print a bit hotter for better layer adhesion, I'm using 90/250 (85/240 first layer) and the print is still very...

Is a derailleur an option? The sim suggests that in this power class a GMAC can be far stronger than a TCDM at low speed if fed enough current whilst retaining regen.

I haven't given much thought to the lock yet. Default option would just be a similar lug extending into a recess in the battery instead of from the battery into the base but I would hope to come up with something more compact. Blutooth is for the smart BMS (long thread in this forum, usually...

Google photos links work, thanks. :thumb: As printed the upper case looks kinda flimsy, but then I don't have it in the hand and I guess it's mostly just an umbrella with the base providing all the structural strength? I plan to build the locking mechanism into the base so each bike has a...

Your images are not loading for me. I'm working on my own designs and might have one assembled in the next few days. I'm not specifically aiming for Hailong/Renton compatibility, I will do my own quick-release base but will probably look at how to adapt to those mainstream plates as it might be...

Note that when using a 16S BMS as a 13S (if supported) its not necessarily the top few wires that are left unconnected. My BMS has a range of 10S to 15S and when used as 10S the connectors excluded are 5,9,10,14,15

I once saw a 3D print of a micro table saw using a Dremel with these wheels. I'm going to make one and add a little sliding caddy to make it easy to cut consistent slots. Should also be possible to cut a few strips simultaneously Need to finish some battery case designs first though. Edit -...

Chinese elephant, running 300 - 500% overrated.

I can vouch for capacitors doing exciting things when abused. Kind of an irrelevant anecdote but; I was once standing in a room directly above our high current testing where we had a big bank of caps each about 3ft tall and a ft square. Max controlled discharge was about 200,000A and a *lot* of...

I can imagine a few reasons; The next ride isn't necessasarily the following morning commute. If it was then starting charge with a timer in the early hours to be ready just before riding would be the most battery friendly. If use is more ad-hoc then it makes sense to keep topped up and rely on...
