Balance CURRENT has nothing to do with balance CHARGING. Balance charge basically takes into account the cell voltage and limit the charge current. Say one cell reaches 4.2v and the others are at 4.0v. The charger will start reducing the charge current to prevent the cell from going over 4.2v until all cell is at 4.2v.
Balance current is only used in the balance function, it equalize the unequal voltage of each cell in a pack. Say one of the cells in your pack is at 4V while the others are at 3.85, it essentially discharge the cell that cell until the voltage matches the other cells. The higher the balance current the faster it balances. In your case, the 4010 has 1.2A of discharge current to drain the cells in the pack so each one of them are the same
ohh so the end phase (balance phase) of a charge cycle cant be sped up or adjusted? and the 1.2a rate is only done in a balance cycle? i never need to use balance function. i always balance charge... i cant believe theres no control for speeding up the end phase of balance charging. a lot of youtubers are "advertising" balance current rating for how fast the battery finishes charging. (balance charge of course)
