Hi,
I bought this Lifepo4 battery pack: link
It came with its own charger.
There are 4 cables coming out of the battery: C+, C-, B+ and B-. Both C and B have 26.6 volts.
I would understand that C means Charger and B means Battery.
The seller told me the charger has to be connected directly to the battery.
When I connected the charger (not plugged into the wall socket) to the C cables, there was a huge spark.
I am totally lost as what C and B really mean and the seller doesn't answer me anymore.
Do any one have an idea?
Also is it normal that there was a huge spark when I connected the charger ? (The fuse on the charger didn't burn).
Please let me know if one of you have any suggestion.
