Ok, here is the values from celllog: BMS stopped charging since few days. I plugged the charger in for 24h, and didn't see any difference. Then disconnected the charger for 18h to see if there is any auto-bleeding... nothing. Charging is stopped and bleeding is not happening. Resistors are...

I could get a new frame, but this is the second I broke. I think the weight and vibrations tends to crack the plastic. It needs some sort of stronger encasing, especially when it's a bit loose. Hopefully epoxy should make it for now... maybe buy another one and add some aluminium sheet to...

Ok, I've put epoxy on it. Let see how it goes tomorrow..

My front bag frame has been weakened due to the bag weight. It has cracks on the plastic now: The bag wobble around when moving the handlebar left to right: http://www.youtube.com/watch?v=7F-Dsv5c5xM&feature=youtu.be I'm thinking to completely glue the frame to the front carrier bloc. Because...

When you say the 80mm wide, you mean the q75?

2 weeks ago, I wanted to go back home around midnight after a drink in a pub. I waited 2 hours to see if rain would stop... It didn't. I decided to go back home cycling under the rain. Hopefully I did that because when I woke up at 10am it was still raining!! So no, it doesn't work in paris ;)

I did that it remains cold

hmm... I do not feel any heat.... maybe because bleeding too slowly?

it's written 2.1kg on bmsbattery spec: Q100 24V250W-350W Rear Driving EBike Hub Motor - BMSBATTERY The lightest one is the keyde motor at 1.4kg with controller inside the motor: http://www.keyde.com/?do=product&lang=en&event=view&ids=07 However, it'll assist you up to 12mph only on 16" wheel.

or also get another controller from another brand? http://www.conhismotor.com/ProductShow.asp?id=103

How can the 2.1kg cute 100 be too heavy? At best you'll loose 0.9kg if you get the lightest goldant motor.

I can't see any resistor on top of the cells: Here is the other side of the bms: I think the resistors are the ones written 390?

For 10A current, a good foolproof one is the EC2 connectors: EC2 Female & Male (5pcs/bag) (UK Warehouse) They are small, with strong connection and last long time. The only issue is that you need to solder them. I would prefer crimping but I haven't found reliable crimping connectors (anderson...

Rather than having a custom front fork, you better extend the rear dropout to put a strong motor in it. Your bike will still fold, and climb any hill. And you won't fear breaking your forks. Weight will also be better distributed with batteries on the front. This is my brompton with an 8T...

I tried a bulk charge with the bms plugged in... Charge stopped when 1 cell reached 4.2V. Cells are ranged between 4.13 and 4.2V. But I didn't feel any heat on the resistors....... I think it's not auto-bleeding?

No, not yet. Haven't solved the rain issue :/

Ok I'm going to charge it full and see if resistors get hots so I know if it's bleeding or not: I would prefer to send her a working battery rather than going back and forth to fix it.

She also told me initially she was able to do 25km with 1 charge. And now she can only do 5km. So it was balanced initially right?

But how do you know it's not a bms issue? Bms should start bleeding as soon as 1 cell reach 4.2V right?

So shall I conclude it's a bms issue? I have the same result with the pack number 2
