charger for 4.35v?

I have some of the new Panasonic 18650b’s that are supposed to be charged to 4.35, is there a cheap charger that will do that?

I think the Panasonic’s are 4.2v charge. I’ve only heard of some LG’s and Sanyo’s that charge to 4.3v.

If you do need a 4.3v charger, there is one sold over on cpf called cotton pickers that can do it.

Well I guess I won’t get a different charger than, haha

Yeah, those are only supposed to be charged to 4.2 volts. :)

Does anybody know where to get 4.35v chargers, though?

Cottonpickers makes 4.35V charger, as already pointed out in this thread (although poster mistakenly said it’s 4.3V)

Your other option would be some CC/CV controller, like LM2596 (it can be configured for CC/CV), but you’d have to manually remove cells as soon as current drops below C/50 (e.g. 60mA for 3000mAh cell).
