e-maxx esc
 

can the stock E-maxx esc run lipo

There is no internal lvc, you will need to wire in an external cut off such as a Novak Smart stop

Hobbycity has a couple alarms. Just make sure if you get a new esc, get a brushless esc with a brushed mode. It has all the features you'll ever want and when it's time to upgrade to a brushless system, you've already got half of it.

EMAXX controller with LIPOS
 

This would work with the Blue EVX 2 included in the 3905? Is this the Novak,#5471,LVC? (If so,this mod would be mucho sweet!! :rules:
Would save some coin,cool!!

On the EVX2, you'll need a 2s Smartstop, #5470. You would then hook it up on the battery lead which feeds the BEC circuit since this will always drain the batteries slightly more than the other side.

To find which side is which, plug a battery into 1 side of the EVX and try to turn it on. If it turns on, then you have the BEC side. If not unplug and try the other battery connection. This one should be the BEC in this case.
