My motorhome had that for the "house" battery. All it consisted of was a 75 Amp silicon diode. :D It was an old motorhome, now gone to the motorhomes in the sky. :oops:

The Astro Blinky balances by discharging all the cells in your pack to some lower common voltage. It doesn't work on A123's since an A123 cell could be anywhere from 20% to 80% charged at a...
