    Balanced charging with Turnigy Accucel-6

    I just bought this pack:
    1x Sanyo Li ion 18650 14 8V 2600mAh Battery Pack with PCM Plug 4Cells to 4S1P X | eBay

    After watching the Turnigy video, it appears there is supposed to be a secondary connector on the battery pack that plugs into the charger to facilitate balanced charging.

    The secondary lead coming out of this pack is just a simple two pin connector that doesn't fit anything.

    What is the method to balanced charging a 4S1P battery pack like this?

    Wouldn't there need to be 3 balance taps in a 4s configuration?

    If the red/black connector is only 2-pin, maybe the 2 connectors interface to the same place in the pack, with the JST (red/black) intended for hooking up to a charger and the round socket is intended for hooking up to the light head.

    It looks to me like the 2 connectors interface to the same place in the pack, with the JST (red/black) intended for hooking up to a charger and the round socket is intended for hooking up to the light head.
    Exactly what I thought.
    Do I need to open up the pack and rewire it?
    If so, any help on how?

    Looks like it's an alternate power hook up. Like a Y cable but different plugs.
    Check the voltage on each.

    I would defer to experts here on whether you need to balance charge that pack. There are discussions about it here and in other forums, but I haven't spent much time on it because I charge loose cells individually.

    FYI here's an applet here that shows you the wiring diagrams for various xSyP LiPo cell configurations, with & without the balance harness.

    That's exactly what I was looking for.

    you do need to balance a 4S pack
    they do go out of balance and the capacity will suffer immensely!

    only yesterday i assembled 4 x 18650 and soldered in a balance lead
    it`s easy, just get a balance lead extension and cut the socket end off then solder it to the tabs on the batteries

    you can actually use the 2 wires ending in the red plug when you wire the balance tap in as they're the outside wires on the balance plug.

    Doh, just read what hondo wrote after writing the same thing

    Check your balance charger manual for which side of the plug has the positive terminal wire and work back from there. If you can't find it, let me know and I'll dig it out of my manual, it's a long time since I've done it!

    OK, I got the new balanced lead extension cables in. I opened up the battery pack and here's what it looks like:







    What's my process for wiring up the balanced leads?
    Do I have to cut the two yellow wires and remove the circuit board to get to the top of the batteries?
