Even better are these cell log devices and if you have the time you can do a lot more with it..... they are also a bit more accurate with balance v measurements....View attachment 16212
You'll end up using 5 of those servo connectors on the KK board set up with S-L switched. The ESC's have their own 3 pin servo's. BTW- If you really want something useful and "cool" for your battery balance lead. This low voltage voltmeter alarm is loud, and reads voltage for total cell count and /cell up to 8S. I have one. It is loud. One can set the alarm voltage. It is relatively accurate based on my multimeter. It reads "more discharged" than actual.
I wish I could try fixed wing flying. My buddies at RCG have been trying to get me to try those fixed wings. I do not think that fixed winged RC and my property are a good match.
