  With  4/5s  it  is  necessary  to  count  with  connecting  the  conductors  directly  at  regulator  (the  conductors 

cannot be drawn on the battery) 

4

  

Practically it is possible to use any kind of battery with the maximum size of 170x45x35 mm 

5

 

As long as the battery-high isn´t over 27mm, it is possible to use a battery up to 48 mm wide 

6

 This battery slightly pushes on the wing, if there is no need to use 5s battery, it is better to avoid it
