Default orion lipo balancing adapter question

Recently got a orioin 3800 lipo and have a triton eq charger. and I've got this question for you guys...

1. As I don't have a multimeter, which wire from an orion battery has the 7.4 voltage and which one has 3.7? It will either be the negative terminal or the small balancing port on the battery..

Loads of stuff for sale- lipos, xxxt's, mamba max system (new), tons of spares charger new

someone can probably give you a schematic but it works like this. Basically what you have is 2 one cell batteries wired end to end in series. The balancing port is neither 3.7 nor 7.4. It IS electrically in the middle of the two cells. This might help. The batteries negative output tap goes to the negative pin of cell 1, the positive pin of cell 1 goes to the negative pin of cell 2 (also feeds the balance tap) and the positive pin of cell 2 connects to the positive output tap. As far as measuring volts consider this: voltage is a relative thing. It’s the relative difference in electrical potential between two points. With a DMM and a 2 cell Lipo I can measure +3.7, -3.7, +7.4 and -7.4 volts all just by placing my meter leads on different points in the pack. Sorry if this is oversimplified. As far as connecting a balance tap you have to make or buy a lead designed to work with the 2mm balance tap on these batteries. Your owner’s manual for the charger and online resources should get you headed in the right direction.

BTW I am currently converting all my batteries over to Deans. I have destroyed one battery and that was enough due to being in a hurry before a race. I also find that eventually banana plugs lose their spring and no longer create a secure connection for the amps we all love drawing. Battery manufacture’s take notice. Unless you really need something like a 6 mm plug, bananas are soooo yesterday. There are much better, safer, options and you know it.
