Re: Reention POLLY DP-6C - 70 cell battery case - how fit BMS?

You need a dedicated BMS, same as with Hailong 2 cases.
I wonder why the seller didn't offer a all in one package.
Bought myself a Polly 1with 13s BMS that fits on top, no problem

Re: Bosch powerpack 400 opening

Thanks to both of you! I will carefully study the battery pack and also measure components nearby the regulator. I hope I will not find any other problems. I will also test the board using a Power Supply to be able to find other broken components without damaging the replaced IC. Regarding the IC, ...

Re: I need help with a problem on my bafang bbs01-b mid drive please help

Make yourself a paper tube of drawing paper with the outer diameter of the rotor and practice inserting the rotor at the old stator without cracking the magnets or shattering the Hall sensors. If the magnets are damaged, at least apply some nail polish there to protect them from corrosion. You might...

The controller might work, but make sure the capacitor that sticks out of the gray poo has not popped yet. If it is domed, it is toast.

Re: I need help with a problem on my bafang bbs01-b mid drive please help

I had pretty much the same experience. Pushing the bike backwards and jumping on it to make my way back home and so on.
You probably fried the hall sensors. Quick fix is a new stator, from greenbikekit or so. Good luck.

For those that already have the cable brake cutoffs that come with the drive unit lying around collecting dust. The switches can be glued into the gap of the Shimano BR-315, BR-447, BR-M615 and so on hydraulic levers as well.You just have to dismantle the switch completely https://www.pedelecforum.d...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I don't know what you have in mind with a PAS Sensor. There's quite a few software bugs you can patch instead. The display cuts off after rolling a couple minutes without assist, the LVC and OVC need to be made adjustable to make the unit work on a 11S battery, and a soft start ramp would be nice to...

There's only tiny magnets next to the hall sensor that enables torque sensing.

Hi @arty, the mid drive rotates towards your downtube. That's anticlockwise seen from chainwheel side
So just place some rubber onto the contact area and that's all.

Re: bbs01 36v 500w stator

The rotor of the 500W (BBS02) is ~5mm larger than the 250/350W (BBS01). So the stator will be larger too.
That's the main reason for the weight difference between bbs01 and 02.
