So this might belong in a discussion of off robot charging, but I'll put here too. Last year we used VEX bats and VEX intelligent charger for our backup bat on FRC robot. Looks like we can still use the bats, but maybe not the charger, which seems far superior in regard to life expectancy of backup batteries.
If we are really forced to use the supplied wall wart to charge our backup bat, we probably won't risk ruining a VEX bat in the process. Seems like a step backwards - and I'm pretty sure DLavery wouldn't use the wall wart on his second car - (on Mars).
