Hi. Certainly not as qualified to answer your questions but Im always up for a chat.
Ive been running A123 for ages and since you have been using them also I assume you already well aware of the voltage difference. So when I say that a Neu 1527 1Y on 7S should be good, that is why 7S (a123 should be similiar to 6S lipo in terms of voltage). I always found the A123 sag more than lipos so not sure how you may find that. Of course you could always add another cell to compensate but then you run into requiring HV esc (typically HV escs are those that handle more than 6S lipo)
The other issue is the capacity of the A123, if you are running the M1 they are around 2300mah, so you are going to need to figure out how many to run in parallel.
From memory they are rated at 70A continuous discharge, so 2P should yield 140A.
I cant say whether this would be enough for the speed you are looking for in that hull. But the Neu 1Y should not be too much of an amp hog.
Not sure how much room you have for cells either.
While you are researching it might not hurt to also consider the Etti 150 ESC and the Turnigy Marine 180A (Hobbywing Seaking 180A) ESC for more budget alternatives.
Many will also mention castle creations hydras as another option.
Anyway, just another point of view and something to consider. Hope you get enough responses to help you make the move to electric.
