RE: Flight Power balancer adapter
Check out the web for adapters. If you can't find one maybe you can make your own. But, you'll need a plub that fits the Equinox. I believe Tower hobbies sells the adapters for the Equinox. To make the adapter for your LiPo you'll also need a plug that fits the LiPo. For wiring you can figure it out with a Volt meter and some testing of the LiPo plug. Usually, Black is ground and each color is a tap to a Cell. So, if you read 3.4 V from say blue to black then that the tap for cell one. If it's 6.8V from say green to black then the tap is to the second cell and so on.
Hope this makes sense.
