So, I need a stand alone switch mode IC to manage/charge a 4 series lithium ion battery pack. But all the ICs I see charge from either end of the battery pack only. So rather than simply placing 4.2x4=16.8V across my 4S pack (as the final charging stage) I need to also ensure that each cell has no more than 4.2V across it - that is balance the pack.
Any ideas on a suitable IC? Thanks.
