Hi guys,
I'm looking to build a device which uses 10 18650 lithium cells in parallel.
I can find a ton of <2A charger IC's but nothing closer to the 5A im looking for not with an English Datasheet anyway.
Can anyone recommend a good charging IC / BMS for such a battery?
Cheers.

Better to charge each one individually. That way you won't need to deal with balancing as each one will be independently charged from the others.

Doesn't apply if they're in parallel and will stay that way once the pack is assembled.
You might want to look at fast charging chipsets for smartphones, but they'll almost certainly be in very difficult to work with SMD packages. I would say to use a standard buck converter with current limiting set to 4.1V and 5A or whatever your target current is, then add a MOSFET to only connect the output when charging.

It's a territory for ICs which use external MOSFETs.
