I have two of these Goldenmotor 16ah Manganese batteries.
I want to connect these in series and charge it one 72v charger.
This ping manual shows how to connect batteries series and protect BMS-es.
Is it possible charge this pack with one 72v charger with BMS protection?
If so, how i connect charger?
Charger + to bat A + and charger minus to BMS B charging port?
Like this?

nope. you will have to charge them separately with 36V chargers.

if you wanna use a 24S BMS then you can use the 72V charger but you have to wire new sense wires to each cell in both batteries so it will have to be taken apart. or you could cut the old sense wires off where accessible and splice the new sense wires to the old sense wires.
 
You can charge both batteries at the same time with two chargers, so it will be faster. Plus you will have a back up charger if one goes south.
