Hello, does anyone have some handy experience advice of removing spot weld nickle strips from 18650? I've tried a few methods, dremmel the spot, pliers, teeth.. but still seem to manage little holes in the battery surfaces. Thanks, Kerry

Hello, With both these controllers costing $85: 36v 350w 48v 350w Is there any difference in the components of the controller, or is it a bit like the 250w/350w 15A/18A programming change? I would have expected some price difference. I am curious as have some spare (identical) cells I could...

Hello, my (unmodified) BBS01b has done near on 1000 miles, including through recent winter snow and on salty-slushy roads. It's certainly noisier than when I got it, but not in a concerning way (a whurr, no clonking, clicking, grinding or banging). I know it is internally (by UK ebike shop)...

An update, seeing as I've been using mine since it was made, basically every day, without any concerns. I put it inside a large Ibera bag which I guess 'floats' it so vibrations is likely minimal.

I struggled recently to try and source a UK based supplier for a recommended BMS, ended up just taking a gamble on random BMS supplier of the moment from somewhere in the world as my battery was very simple anyway. Seems to do the job. The next stage, consider how far you wish to go. Passive...

Righty, success. Each cell unit now all show the same voltage (4.12v). This took several do-overs. It seems a bit sensitive building it, for instance once rebuilt again (after each individual battery connection tested) another different group would appear higher. One of them, clearly...

Is there a technical reason that metal framed ebikes don't use the frame as a conductor, like cars do? Seems a logical way of reducing wiring looms.

So, I pulled all the bus bars off and retested every cell. Found only one which had no contact. This was fixed. A bit of balancing was done to try and get the cells around the same voltage, then the load lamp connected which pulls 2.6A (measured). Alas, by the time it was finished charging...

I used all of the ties which came with it the first time, then had to cut them off. I have a bunch of ties ready once it is finished. The new ones are industrial strength, ~1cm wide. The pressure points of the ties though are on the edges. In the middle, I could easily get a fingernail...

This is the bit that I'm worried about overall for reliability now. I tested the voltage of every individual cell - both as the caps were put on and then again once it was all snapped together having used two planks of wood to ensure there was even pressure all over. So somewhere (and it makes...

I quite like the idea of this from the 3D printed example "The thin black backing is the Poron foam, which helps to maintain pressure behind the bus." rather than relying only on the hinge formed by the metal. Mind you, that is a whole new level of work to make a battery which most of the...

Thats quite an awesome little kit, might get it anyway. The multimeter, should be OK I hope. Its a decent Fluke, with true RMS (not that it will help with DC..) I think this weekend, I will build a small array of light bulbs as a load. Lower the voltage of the high cells - rebuild the...

I am hoping, a bit of advise might be helpful here. I've built a battery (more as a learning thing - it's not the most compact thing to put somewhere on a bike), looks like this: The BMS is https://www.amazon.co.uk/10Series-Protection-Balancing-Li-ion-Battery/dp/B075MFBB23 charger is...

Claud Butler Hybrid - 700c, bbs01b ~250w, DIY 36v 15Ah battery.

Though, with their own software loaded on it too. Looks very simple to use. Probably if you need to do changes lots, or go though motors it would be quite handy to have. I built my 'cable' for ~£3 from a USBTTL adapter and use stick pins, with the handy free software which does the rounds...

I wonder, if some of the BBS sold are missing the rubber seal? In comparing installs with another rider (different suppliers, mine had been pregreased inside for instance), theirs didn't have the seal (unless it was the most perfect alignment and not a single bit showing) I've had a couple of...

Please pass on my regards to Woosh Support. nealh, many thanks will give it a shot.
