You will end-up with an odd pair that contains one module from each set, put that module on the middle near the temperature probe.

Do not try to place two "strings" of batteries in parallel as it requires a lot more electronics and safeties in place for a proper design.
You have "confirmed" my thinking on this one. I realize there will be an "odd man out" so to speak, and I don't want to add another BMS to the mix. My 16 cell ZEVA will handle this kind of upgrade.

Frankly.....the only reason I even want to do this is so the Mrs. and I can travers the ATV trails in the Allegheny National Forest. Some of those trails are 30+ miles long and I'm doubting my 7 module pack will take me that many miles.
