Evo2 Lipo Battery
So I'm upgrading my nifty brobot to EVO 2, just 'cause. Nice work JJRobots on this kit!

The original has this simple config area to specify behavior for lipo and save your lipo battery from too low a drain:

But then I don't see this in the new Evo2:

Is Lipo not happenin for Evo2? Maybe I can't upgrade if too risky for my Lipo.

Hello, i make a second robot myself, using the standard hardware from JJROBOTS ( you can find info in my following post ), but this time i downloaded the new software EVO2. In this case the battery test was non yet implemented, but there is no problem regarding the use of Lipo battery ( i use 3 cell 2200mAh, 12,6V full charged ); the only warning was to avoid supply voltage too high, overloading the regulator on Leonardo board. The real problem for Lipo is the unbalancing voltage cell to cell when discharged, but this problem can be easily solved with a balancing connector ( all Lipo are fitted with this ) and a proper charger. Of coarse when playing with the robot, we need some attention to test sometime the Lipo full voltage, avoiding to discharge below the 3,1-3,2V per cell . I am trying the modify the EVO2 to send the battery value by Touchosc, but this is another story... ( sorry for my bad english, i will try to do it better ).
