I would like to build a small fusion reactor cell, suitable for a pedelec. Once I've achieved that, without collapsing gravity, world domination should be within reach.

Here is what I've got: B0-B13 are the pin labels. B13, also seems to have COM written next to it and this was what confused me as I couldn't work out then why there are 6 wires from B0-B5 then gap (filled in with glue) and then 5 more. It makes sense what you've said, that the first black...

OK

Is there a standard layout for BMS boards? I've got one which is originally from a Woosh made? battery held in a HL case but can't seem to find any data for the BMS. Most of the pins are obvious like the temp and the battery level and the connectors to the battery packs/charger, but the balance...

I am left with just 20 unblemished cells :( the rest are off to a recycling centre today. On the bright side, all with extremely close voltage readings. Well impressed. Which probably also is a big tick for using Hailong and Samsung suggesting the entire battery was well balanced. They do use...

I was kinda right about insulation, more a membrane tho... Alas, insurance attempt seems about the best way forward... In Lithium-ion batteries, cathode and anode are separated by a thin – sometimes 10 microns – polyethylene separator. When this separator ruptures, a short circuit happens which...

hmmm... in thinking... shall not cause 'fire or explosion' probably should have re-read that line a few more times... being that is the minimum outcome...

I had read this spec before posting, genuine cells seem fairly high spec before being written off: https://www.batteryspace.com/prod-specs/ICR18650NH-2200.pdf 7.4 crush A charged battery cell is to be crushed between two flat surfaces. The force for the crushing is to be applied by a hydraulic...

What happens when an ebike battery goes under a bus wheel So, next question is... what now? Most of the batteries are just dented and the circuit board for the battery conditioner is fortunately fine. Where might I find a pinout for the conditioner? What are the chances that the cells are...

Is the bafung protocol, more or less a standard? If you got the display, would it need a firmware uploaded or plug and play?

I am wondering, just how much #8 wire my bike can take? :D

Cheers for the reply. In a little further searching after posting, I came across this article: http://www.poweredride.com/info/dump-your-bafang-display-for-stealth-and-better-display-options And interestingly, sums up your response: Alas, I'm trying to keep everything within warranty...

Hello, the display from Bafung (and others it seems) is quite large. I've replaced a small, roughly 5cm diameter speedo which the display was more than adequate for its requirement with the monster which takes up a huge amount of handlebar real estate. For something that gets glimpsed at some...

Have you come across self amalgamating tape? amazing stuff. have a bbs01 and have tidied my cables up with this. This link to a manufacture video, can't comment on their particular product as haven't tried it. Mine was 'random generic some name I forget'. Nor, can I comment on longevity...

Hello, i have a 36v battery and wish to run lights from it. Simplicity, I currently have a 6v front nice and bright fella. Is it worth putting in a 36v-6v DC-DC converter, or 'upgrade' and build something with 3 x 12v LEDs in series? If the converter went in parallel with the feed to the rest...

This will do wonders for the bike retailers re: warranty. The future, a bit like Bosch would want, where you can only get the motor fixed by a certified fixerupper person and only order parts through channel partners. I guess, much like car engines where replacement parts are coded to the ECU...
