Hello all, I picked up a couple Pulse flight packs from a member here- here's a link . The previous owner had installed EC5 connectors... one connector on Red and Yellow wires, another connector on Black and Yellow wires.
When I connect the Red/Yellow to my iCharger (with balance board connected) it shows me the voltage and everything is good - Red being Positive and Yellow being Negative.
When I take the other side wiring and connect the Black to Positive and Yellow to Negative it shows me an error and tells me the wiring is reversed. When I reverse the wires it shows me the correct voltage.

What's the correct way to charge these batteries?

The R/Y batt. has R = positive and Y = negative.

As you discovered, the B/Y batt. has Y = positive and B = negative.

Charge them as the above indicates.

Dingo, I believe that what you're seeing with the R/Y and Y/B color codes is this:

The previous batt owner was using the two Pulse 6S batts in series to form a 12S battery supply.

What you didn't see was that on the previous owner's ESC was a wire that connects Y to Y on the ESC connectors.

And that's an excellent way to color code such a series setup.

Hat tip to the previous owner....

It's then easy to see what connectors go where.

FWIW

thank you for the quick response EEngineer! That's what I suspected, and that's how I wired my ESC so I have less connections. Because I'm new to electric and Lipo's and the charging setup I just put together, I'm mentally spent and didn't want to risk blowing up a pack and burning the house down. It still scares me a little when I connect the leads to the iCharger, but I'll get used to it Thanks for the clarification, I can charge with confidence now

Always check with a proper voltmeter before connecting battery packs on your charger.

You were lucky... Most of charger doesnt have protections against reverse polarity...
