originally the charge connector is directly connected to the + and - connections of the battery.
but the BMS i use, has a separate charging circuit. so you need to use 2 different connector pins for charging
so i cut the red and black of the charge connector, underside battery unit, and soldered them to the middle pins.
then inside batterypack, use these 2 wires to connect to the BMS charging circuit.

on the picture you see bottomside, wire output from battery, 2 thick red/black is output.
the other 3 thinner wires where for old controller, not used again.
then other from charge connector, i soldered them to middle wires.

meassured for room, but also next to batterypack, inside the frame, there is less room to fit a controller.
so i think i'll go ahead and order a 1000W, 43mm thick controller and try to work that inside the footboard, make it thinner or take out a piece of the underside footboard and work with that.

waiting a couple of weeks for Ali.....
Hi,
I think I understand what you did ...
I need to take care of this to not do mistakes

That is what I have originally on the bottom of the battery case :

Hi dijkie
I would like to buy the BMS to unlock the battery.
I think that on Amazon they are sometimes faster to send the products.
Which BMS product could you advise me to buy :?: : (see below link on amazon)

i have the one with the Red and Yellow wires
30A version.

choose the cheapest
Yeah that's what I mean to do but I have read some comments from people who have bought these types of BMS and some of them says that it's cheap and don't last long (some battery charges / discharges) and end of the story.

Anyway there is no choice because we need a no blocked BMS

When you have installed your new BMS you have charge the battery to 100 % ?

yep, left it in for a night and the controller display showed full charge.

we can only judge about the quality of this BMS after some time of usage.
some charge cycles and some trips 10km full throttle uphill or something like that.
untill now, for the 30seconds the controller worked, it seems fine.
