ES2 Slowdowns during high speed with extra battery
 

Hi,

I recently bought an ES2 with the extra battery (ES4) and once reaching top speed it is not a smooth ride but every couple of seconds there is a slowdown, like someone is applying a brake and immediately releasing it.

* It only happens with the extra battery (removed it and the issue is gone, maybe because I didn't reach the max speed).
* It only happens when battery is lower than 70%

Any idea?
