Help me understand my Emaxx

[turbo4]

Here is what I sent dimension engineering and their response:

Hi, I bought a liposhield for an emaxx monster truck. Im using 2 2s2p
> 6000mah 7.4v packs. When the liposhield \"kicks\" in what should be

> I\'ve had a few instances where the truck wants to run in reverse on its

> functions of the esc are foward/brake/reverse, with a slight delay between
> brake and reverse.
> Also when the batteries are getting low I get a \"stutter\" upon a

Hi Joel,
LipoShield is mainly aimed at r/c planes that have a throttle going from
0-100. When in cutoff, the throttle will slowly be scaled back towards the 0
position, in proportion to the battery voltage. In a car configuration,
you'd typically have 50/50 throttle or 30/70, so the 0 position will
correspond to a full brake or reverse. Unfortunately there would be positive
feedback in this situation - if the battery voltage gets low, the car starts
driving backwards which will lower the battery voltage even more. Basically
if you want to use LipoShield/Cellshield on a car, when you start getting
odd behaviour it means that the battery is drained. We do have an upcoming
product aimed at cars that will have a throttle rollback better suited to
cars/boats - it is in beta testing right now.
Please let me know if you have any more questions!
