Hi,

I would like to use a specific Panasonic charger Biketec 29.3V 1.8A to charge a standard 7s5p 18650 pack.
How to start it?

Thank you
 
Most chargers like to be plugged into the wall first.
There is a ez way to add a photo when typing your post underneath. Check the polarity of the plug and battery first.

Yeah you always must check depends on how your plug is on the charger and the battery which is negative and which is positive always check.
 
Dear 999zip999 certainly that I plugged it onto wall socket.
At the output of the charger I have 4 cables: red black yellow white. I don't have the original battery anymore.
Reading between red and black give 0V, between while and red 4.2V,, between black and white 4.8V.
I think that the charger needs to obtain from the bms of the original Panasonic battery a specific value to start the charge. Does anyone Panasonic expert knows the pinout of these chargers?
 
Images shows only that I wrote in the post.

I search infos about two cables shown in the third pic which going out from original bms (yellow and white)
