RE: Scorpion 2S Lipo Charger
After doing more research myself, I fought out the following. The charger you are looking at is the 6s(which has the four wire setup you mentioned), but mine is the 2s(which has a 3 wire setup). The 2s which FMA direct still sells, has an adapter that will charge Team Orion's and Peak Racing style LIpo's(hard case with 2 regular ports and 1 balancing port). After talking to FMA direct, they still sell a pigtail with a 2s port plug and 3 unattached(bare) wires. This part is available only through request. I then called Maxamps and they said send this pigtail to them and they would wire it into the battery like they would other brands you can preorder balancing taps.
What is weird is that the newer 6s,which does A123 batteries as well, does not have the same adapter to work with Team Orion and Peak Racing.
Duralite now makes a RC car battery similar to the Team orion and Peak Racing. Now throw in MaxAmps working with me, I have at least 4 brands to choose.
The 2s was only $25.00, a couple of adapters and I am only out $40.00 for a 10 amp lipo charger with balancing build into it. Awesome.
Thanks for your response
