As I'm sure you have seen, I have started, and charged my first battery on my charge case build, which has been in the works for over 4 years. Because I wanted to move over to XT30/60/90's from Deans Plugs, I purchased a parallel charge board to integrate into this build. The output is run from my charger to the BuddyRC Parallel board with Deans connectors, then it is passed through to the XT board. Simple enough, right?
When I plugged in a battery from the XT board, everything worked perfectly. I was able to charge packs and I was able to check cell voltages and IR. But, when I plugged a battery into the Deans board, the cells lit up in the wrong spot and if I connected the balance lead with the main power connector, all voltages disappeared. Little weird.
In my setup, I have a long and a short balance lead. The long lead was on the BuddyRC "Deans" board, and the short lead was on the XT board. I plugged them in just as they were wires and as they only fit one way, I didn't think anything of it. Now remember, everything on the XT board worked great! Deans, not so much.
Then I looked at the cables. The BuddyRC is a crossover cable, and the XT board is a standard cable. The XT board is not pinned the same as the BuddyRC board.
Moral of the story is, before you start combining boards together, check the polarity of the cables, because one manufacturer may not use the same pinout as the next manufacturer. Just glad this didn't let the magic smoke out of anything...
Notice anything odd in the following pictures? Take a look at that last image of my Pulse 6s 5000mah pack plugged into the balance board... That black wire is NOT where it is supposed to be....
