Hi all enjoying e-bikers !
I have found a battery (Ping Battery) 36v 30ah and have ask some answers to seller.
Some exctract to help you understand :
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Usually, we don't recommend regen function with our battery packs. Anyway, if you don't run it on a long downhill road when the battery pack is full, there won't be problem. But please limit the regen current to be lower than 20a with our 36v30ah pack.
The BMS stop the charge. So, you can plug the pack to the charger all the time and it won't over charge the pack. However, usually regen breaking power comes through the discharge leads, while our BMS only protects the cell against over charge through the charge leads. Our battery pack has two pairs of leads, one pair for discharge and the other for charge. So, please don't open regen power when the battery pack is full. I'm not familiar with Goldenmotor's regen system. If the regen power of the controller comes from another leads than the power leads, you just need to connect them to the charge leads of our battery pack and don't need to worry about it.
I'm always willing to answer your questions.
Best regards,
Ping

So I would like to know if it was possible by a diode system, inverter to seperate the power wires of the controller to connect in-power to controller with the discharge leads of the battery and to connect out-power's controller with the charge leads of the battery to haven't any problem (burn).
It's very important because I would like always use regenerative breaking function to stop the trike (11 inchs motorised wheel).
What are the wires I connect to discharge leads/charge leads with diode ?
I'm sorry to ask to much questions but if a christian soul can help me.. Why not :)
Bye

Re:
I have made a diagram.
I will see later for the diode 's polarity (i must learn ;D)
Whay do you think ?
C-
O- |------------------------|<|------------------- + battery discharge leads
N---------- +|-------
T- |-------------------------|>|-----------[20AFuse or resistor]-------- + battery charge leads
R-
O-
L-
L- |---------------------------------------------------------------------------- - battery discharge leads
E---------- -|--------
R- |---------------------------------------------------------------------------- - battery charge leads
|<| is diode
Sorry, no host for image
I have read on this forum if the controller is not connect to the battery and the motor is regening the controller will burn.
So when my battery will be full the controller wil burn (BMS stop charge)
I've not understood all (it was in english)
Any idea ?

Isn't possible ?

Greg,
Your circuit may work, but I don't know for sure.
The diodes will also give a slight voltage drop (probably around 1.2V) between the battery and the controller, this might cause the LVC in the Controller to cut out slightly sooner than it would without them.
You might find the diodes are only required on the +ve side, if the charge lead and supply lead use a common -ve connection on the battery.
Has anyone tried anything similar?

Thanks you,
I've modified the scheme (no diode on - :) )
1,2V isn't important so it's good.
I must know choose a diode for 40A and 20A max current and learn about polarity.
