Re: Tetrx Minibot Battery Charge Cycle during Regional Play

It looks like it will be important to carefully manage battery usage. We will likely top them off between matches and alternate batteries.

That's pretty impressive that this battery hangs on to the voltage for that long in the upper 12 volts. That should keep the minibots pretty consistent in the race to the top even on a so-so charge. Nice work Hugh!

PS: We've been wanting to get one of those CBA II analyzers ourselves. This year might be the year...
