RDDRONE-BMS772 vs FRDM33772BSPIEVB for solar drone using the lithium polymer battery

We are working with solar drone which requires a lot of power.

RDDRONE-BMS772 seems very nice but i am confused on the maximum rating.

We have 6s configuration Lipo battery which is 22 volt and more than 30AHr, and the motor can require a huge burst current and continuous current (90A for minutes, per se). I see that the continuous maximum rating for this is 90A DC with 4 MOSFET heatsink attached.

My question are:

1. Is there any other model, then the RDDRONE-BMS772 which has more maximum current capability then this one. 

2. What is the maximum burst current and time limit for the burst current. Can you please suggest me which can be better for me this one or the other BMS FRDM33772BSPIEVB.

3. Is it easy to use the I2C communication with the raspberry pi.
