Hey guys, I have a problem with my charging setup which I don’t understand. I have 4 3s Zippys running 6S2P and am trying to charge them using a parallel charging board and an iMax B6 as so:
Both of the main power leads plug in fine to the board, I plugged in one balance cable but whenever I try to plug in the second balance cable it sparks a lot and burns up. I don’t understand why this is happening, the voltages seem correct on the balance pins, I can measure across and it goes 3.7, 7.4, 11.1, 14.8, 18.5, 22.2. The other balance cable is setup exactly the same and works. I don’t think the parallel board is faulty because I’ve got it to work in the past and I tried multiple ports on it with the same result. I check the continuity on all the pins and they seemed okay too. Here’s the parallel board (without the balance cables plugged in)
Thats where it burned previously so I’m not using that port anymore. And ya I checked the continuity from each pin on the balance ports to the output pins on the balance port… not sure what else to check
Edit: Ya charging just 1 worked, but I have actually been able to successfully charge both at the same time before using this board in the past.
