my best bet will be the fast charge then . ( leave the balance plugs unplugged altogether .

That's the one thing I'd personally never recommend, cos it really is rather unsafe. In fact, iChargers won't even charge that way. The balance plugs must be connected.

Many (most?) lipo fires during charging start because a cell is forced way beyond 4.2V. Say there's a 2S pack being charged with the balance plugs disconnected, and one of the cells happens to be on its last legs. The charger sees 8.4V as the termination voltage, but without the balance taps is has no way of knowing whether that's comprised of 4.2+4.2, or 4.1+4.3, or even 4.0+4.4! That last one is liable to start a fire.

For safety's sake, the balance plug should always be connected, even if the charger doesn't insist on it (in which case I'd suggest buying a safer charger).
