Balance cells using a parasitic drain while charging

[Handlebars]

After reaching 100%, will draining the battery by turning on the lights, drain the higher voltage cells and thereby help the balancing process?

Anything is possible I suppose, but my logic would have any draw on the system pulling from all cells equally - no matter their cell voltage. To pull from higher voltage cells first could be done, but would need a special circuit not there now.

Thank you Mr. Hicks. I've noticed that after a long long charge past the time when it first reads 100% resulted in very little reduction in the first mile of riding, whereas use after the charger light first changes is now resulting in up to 14% reduction immediately on the first hill less than 1/8 of a mile, which bounces back up to maybe 8% only loss after a short rest.
In other words, the battery shows quicker loss when full than later on in the same ride.
I'm doing the extra long "after 100% charge" right now again to see if I get that result of not losing so much immediately.
Previously I had measured with a voltmeter at 100% and found it wasn't fully charged. Leaving it on for an hour or so helped, but only long charging after 100% got the battery to full voltage.
I suspect some weaker cells are in there.

Some guys poo poo frequent balance charging. Suit yourself, but I'm a big fan.

It performed much better under same conditions same ride today but with long charge. 14% loss was after returning home so almost halved the voltage loss.

These packs don't 'balance charge' cuz there's no circuitry for it. You would need a sensor wire from each cell pack - they're simply not built that way AFAIK.
