XY-L30A charger module HW-749

Locked

Discussion interactions are currently paused.

I wanted to know about the CH+ and CH- terminals on the module in question, what voltage should be applied? DC or AC 220V? And then on the RX TX GND contacts what should be connected?

Thanks to anyone who replies

Hello,

it's not a battery charger... but a charge control module.

I only see four terminals:

CH+ and CH- (since there are + and - markings, it's obvious that the voltage must be DC, i.e. 6 to 60V depending on the battery to be controlled)
BT+ and BT- (the battery must be connected there)

I don't see any other terminals...

Kind regards.
