I have configured 10S5P lithium power pack, because the old lithium batteries had almost no capacity.
So I am having the following problem, the old BMS is a 8S BMS, because I have configured 10S battery pack I cannot use the old 8S BMS, but I want to use it because the old BMS has a chip on it so it sends a signal to the bicycle with it's ID. Whenever the controller of the bicycle reads the chip it checks if the ID is the same as programmed.
So, now the following:
- I want to use the old BMS still be in place for the chip that is programmed with a bicycle.
- I want to use 10S new BMS
So how do I connect the old BMS with a new BMS? The new BMS will be connected with the battery pack And it has -P (Power negative), -C (Charging negative) and -B (battery negative).
The old BMS must be able to power on, but the new BMS will be doing the balancing.
