What kind of batteries can be used with a Jetcat ECU. My STP5 turboprop came with a 2 cell 7.4 V Lipo battery but I was wondering if I could use a 9.9 V Life battery.

The reason for asking is that I use this 9.9 V Life batteries in all my other Jetcentral turbines and it would be nice to be able to just have one type of batterie in order to standardize.
