Mike,
The guys at XS Power say charge before use, and mentioned that a small charger will not work, but the BT FAQ seems to point to it just taking a long time. For an initial charge do you ever "restart" the charge cycle, giving it multiple "hits" at 14.4V? Or do you just put it on a BT Plus and leave it for several days?
