Why 2 connectors on bugs 3 red batteries and types of connectors

Hi--
I am trying to figure out how to charge my new bugs 3. The charger supplied with the unit doesn't work, so I'm going to buy a new one as recommended by several of the forum posters, but I need an adapter. It's frustrating to have a new toy and not be able to use it. Here are my 2 questions:

First: There are 2 connectors attached by wires to the battery supplied with the bugs 3. One has a xt30 connector, which plugs into the bugs 3. Can I use that line to charge the battery? Or is it only for power coming out of the battery?

Second question--I cannot figure out what type of connector the other (white) one is. It's hard to match it looking at photos. Does anyone know? It's the one found on this battery (see below).

Wwman 2pcs 7.4v 1800mah 25C Li-poly Batteries for MJX B3 Bugs 3 RC Drone Spare Parts
(can see on amazon, but I'm new to this forum so can't put in a link).

Thanks

That's the balance lead.

You have a 2S battery which is two 3.7V batteries in series. The balance lead has a 3rd wire it allows for reading and charging each individual battery in your 2S Pack (2x 3.7 = 7.4v, note fully charged you'll be at ~8.4V.)

Sure, but both cells may not end up charged equally, they may not be balanced.

Even the cheapest 4 button chargers will have the 2S balance port. Note this is a copy.

Depending on the charger, that second smaller plug with 3 wires can be your charging plug or your balance plug.

This kind of charger does both operations thru the small plug....charging and balancing(making sure both cells are charged the same). The drawback with this type of charger is that you are limited to smaller charging currents due to those smaller wires.

And this is the charger I use. You'll note that there is multiple plugs(small) for different lipo cell counts......2s to 6s. For the purpose of balancing the cells. But you'll also note there are two "outputs" for larger wires and these carry the main current for charging your battery. This particular charger has a maximum current output of 5 amps.
