Sold! BBS02 complete kit (damaged) $50

Hi. I have a complete BBS02 kit here with the new version controller, new chainring, and screen etc - everything that came with it. Damage: The gears are stripped, plastic ones completely worn through and the metal gear has seen better days. Could be repaired by someone who is willing to open it up ...

Re: First battery pack build

Batt complete! Added a few picks of my setup above. The pack is working pretty well - at the start it was about 5% unbalanced, but i've used some 10ohm 10w resistors over a few days to balance it to within .01v, now i'll let the bms take over. The CA reports a battery internal resistance of 0.102ohm...

Re: CHEAP ORYGINAL CELLS 18650 and welded packs for 36V

I recently received 360 GA cells from tumich posted to Australia, in good condition. Now that I've built the pack and the cells are exceeding my expectations, I wanted to add to the thread here to confirm that these are genuine cells and working very well. I've quadrupled the useable capacity of my ...

Re: First battery pack build

Thanks Marty. The SSR I used was the fdtek ssr-40 da. Couple of bucks on eBay, and it's supposed to handle 380v up to 40A, so should be well overkill for this purpose. I'm simply driving the input side directly from one of the 5v arduino digital outputs, and the output side is switching the 240 on t...

Re: LiPo fireproof wrap?

Probably a good idea - however, just because the product can insulate to 900 degrees doesn't mean that lipo is safe because it's in the bag. When lipos go up in smoke, they emit quite a lot of combustible gas. Even though the bag may shield you from the temperature of the battery itself, it can't do...

Re: BBSHD and a 15s battery

14s hot off the charger is 58.8v. That's already a wafer thin margin of safety. There is no advantage to exceeding that, and many disadvantages - either you'll exceed the HVC and not be able to ride at all, or you won't be able to fully charge your batteries. Also, your battery will be an odd voltag...

LIQUID NAILS

I've never liked hot glue - far too weak. Planning to build a battery pack glued together with liquid nails. Should be a lot stronger than hot glue. Any concerns?

Re: 18650 spot welding -how to- ULTIMATE REPOSITORY

And for some reason copper/nickel mixtures have worse conductivity than pure nickel. So i wondered whether t...

Re: Michelin X Tweel Turf tires

These are the real deal. Check out these durability tests:


And comparison with normal tyres:

No serious bike oriented options yet from what I can see. How good would that be? Especially for those of us who don't have room in the triangle for a rear suspension.

Re: Bafang BBSHD, 1000W, 68mm-120mm BB

Am I the only one who just bangs through the gears? I've been doing this for 1,000s of miles. At full throttle, all you have to do is wait for the motor to start spinning out and the amps to slightly dip in the current gear you are in, and then just click into the next gear, usually a smooth shift,...

The battery is 20AH of multistar 10c lipo - so in theory, good for up to 200A. I know I can easily draw 80A with around 2-3v of sag. I can run ...
