Chargers Beware - Charsoon parallel board

[bigone5500]

Got this board from aliexpress and upon connecting it to my charger and pluggin in a battery, it told me it was reverse polarity. What's up with this chinese junk? Sure I can just swap the banana plugs but that ain't gonna cut it. I'll resolder the wires correctly.

If you have not done this yet, take some pictures before and after you resolder the wires. I would like to see the inside of the board. Mainly because I have a Charsoon battery and you have me wondering lmao. A little worried about my battery now.

This board is just a single sided pcb with the connectors on one ssde and the paths on the other. Got small solder pads to hold 14 GA wire. Nothing special. I can get a couple photos if you would like to see.

What batteries are you plugging in to it?
I have some 1s batteries that have short leads and similar plugs for various small quads and I have to be careful because they will fit in to the wrong port.
They are wired differently in the plugs.
To change them would be a nightmare as I would have to also perform micro surgery on the respective quads.

I have the battery that came with my ares nanos heli and a 200mah for my blade mcpx. Both have different size plugs and if I were to plug one in and connect it to the charger, it would tell me reverse polarity. So I simply switched the leads on the solder pads.
