I have a 52V (14s2p) battery with an XT90s (anti-spark) connector that I've been using on a BBS02 for awhile with no problems. I recently started a new build with a TSDZ2. I hooked up the battery and did a test of the new motor with an existing bullet-to-XT90 cable I already had (made it for my BBS02), and there were no problems. Then I cut off the factory bullet connectors from the new motor, soldered on the new ones (the old ones were not the length I wanted, and bad quality). Then I made a new bullet-to-XT90 cable.
I hooked that up and, and when I did, immediately burnt out the resistor in the XT90s connector on the battery. I figured maybe I plugged it in too slow, which resulted in current flowing through the resistor for too long, so I made a XT90s female to XT90 male adaptor and plugged that onto the existing XT90s connector on the battery (the one with the burnt resistor now). I plugged that into the motor, and the resistor in the *new* connector immediately burnt. That time I had made sure to plug it in swiftly and smoothly.
What's going on? Why am I burning out the resistors? Could it be a problem in the new cables I made somehow? I've confirmed (many times) that the polarity is correct. The anti-spark connectors are a little pricey and I only have a few of them so I don't want to keep burning them out with random experiments. Thanks!
