If i run two 2S lipo's together to make 4S in a Losi TEN-SCTE, with a HobbyWing Xerun SCT Pro ESC, and 4274 2200KV motor, will the XT60's that are already on the batteries and ESC be sufficient, or, do i have to swap to XT90's? If i have to swap to XT90's, so that i dont have to convert all of my cars to XT90's, can i just use adapter's to go from the XT90's on the batteries to the XT60's on those cars (mostly 2WD SCT's and 2WD buggies), or, do i have to replace them all? With as many currently running vehicles as i have, and some being brushed, i dont want to have to spend the extra expense of swapping them all to XT90, unless it is absolutely necessary. I also dont want to spend the money on a single 4S for just that one truck, since it wont be ran a lot, and will be the only 4S truck i own. I currently have about a dozen 2WD SCT's and buggies, and 3 MT's, and only 3 of those are 4WD (i am not really a fan of 4WD to begin with, but, winter in the northeast makes its hard to run 2WD), two of which are staying 2S.
