4s M1 A123 cells on Mamba Max 5700?

Well I better take it easy then...

Yeah, last year I had an on road 1/6 scale car, dual EVX's, dual dewalt 820 motors, I ran 6s A123, although, straight off the charger it would sometimes cut power, once the motors turned over for a few seconds the voltage came down enough for it to run fine.... and did it ever! :017: Prossibly 1000 watts from two brushed motors, they were very durable.

Silly me, correction... 5s2p A123 is ~180 grams lighter than 12 cells NiMH.

So if 5s2p fits inside the boat, I might just go that route, I will see.

How hot do the M1 cells get? I just got back from the lake, running my Villain on 14 GP3300s, and those cells get way too hot to touch after a hard run. Of course, the batteries aren't exactly spring chickens, being about a year old (the 19th will be their birthday:cool:), and being run a lot in my used-to-be-brushless Maxx, the batteries didn't have an easy life, so they could have developed some resistance that will make them get hotter than they should.
I just don't want the M1 cells to melt a hole in my boat and sink the whole thing:036:. I read about them a bit in the newest issue of Popular Science, and it tells how they work and everything, also saying they can withstand heat up to like 400* without being damaged, so durability doesn't seem to be an issue.

Thanx,
Brijar!!!
