Roger, from my testing, the 350MA can stay there for hours once the cells are topped off, and that is required for the first full charge just to make sure that all cells get filled.
This is why I recommend having the a fan running.
If the grid chargers open circuit voltage is set too low, so the CC drops voltage before the weaker cells get fully charged, some cells will not get balanced, and you will see decreased current on your killawatt.
When the charger open circuit voltage is set to say 175 or so, the pack will never reach that voltage, and the AC current draw will stay the same throughout.
IMHO A simple timer to stop the whole charge process may be the easier solution if you want to stop the charge if you forget.
