Most new chargers always do a proper charge & balance by default. My Bantam chargers have a fast charge option but that still balances and saves time by only charging up to 95%. I can't see the logic in trying to save time by not balancing - get a charger that puts out enough current to charge your packs quickly and balance every time so the cells never get far out of balance in the first place, so the problem mentioned in the video never happens.
