JMT 10Pcs XT30 Plug Pigtail Power Wire Cable 100F Capacitor for Happymodel Mobula7 HD Sailfly-X UR85 UR85HD Crazybee F3 F4 PRO RC Racing Drone

Item name: XT30 Plug Pigtail Power Wire with 100μF Capacitor
Wire length: 70mm(include xt30)
Height: 2.6 gram /Piece
Used for :  Crazybee F3 / F4 PRO series flight controller
Quantity: 10 Pieces

Can avoid the risk of burning the mosfet or the 5v regulator at the moment of power on
With this Capacitor , we can use 3S 300~350mah battery for the Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1 , and 2s 300~350mah battery for the Crazybee F4 PRO V1.0 
And if you want to use the battery above 350mah , we recommend use 220 μF or above capacitor.

We found most of the 5v regulator and esc of the Crazybee F4 flight controller burnt after mod the PH2.0 to XT30 . Also, more powerful the battery is(lower esr than stock battery) , more possibility to fail. And, the temporary solution is add a low esr capacitor onto xt30 connector. This capacitor should have a esr less than 0.2 ohm and have a capacitance more than 100uF. Rubycon ZLG/ZLH series and Samyoung NXB series are what we have tested and recommended.

Following pictures show what happened after plug in battery:
The max voltage is 19v and the voltage spike lasted for about 5us.After add a 100uF/16v (NXB16VB100M5*11_LO) capacitor, we obtained a much slower and smaller spike:
Further more, we replace the stock 300mAh/3s(40~50mohm esr) to 550mAh/3s(~20mohms esr), the result turn to be more worse:

Without 100μF, the max spike voltage increase to ~25v while with 100uF it decrease to about 20v, which is acceptable to Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1
