The motor might be getting hotter because the MMM is capable of higher current and will have lower resistance while doing it. This means you run you motor hard during your runs now than you used to...

I would expect slight less run time. You motor will be demanding more current and if you are not getting up to your top speeds, will then be running less efficiently. From my experience you need to...

I don't think a 10xl would be pushing the mamba too hard. In fact that might be sort of a light load. I am running my 10+ lbs truck on a 9xl motor and a mamba max. I do have a fan on the mamba...

Isn't horsepower a unit of power and torque is just force. We can convert HP into watts but not torque to watts. Heck I can put a bolt on at 150 FT/lbs but can't move it at that rate more than 1/8...

This temp seems fine. If I am not mistaken "hot" would be over 150 degrees. So if you are doing 140 you are doing perfect. I run about 143 after about 15 minutes of running my 9xl on 5s2p A123. ...

my 1210i will accept all the way down to 10.2v then get a low battery warning and shut down the charge. I have never tested the upper limits though. 0610 will take anything from 11-28v input.
