LiPoly battery pack - chargers?

Hey!

I’ve got myself a “Lithium Ion polymer Batteries pack - 3A”.

Now I have a LiPoly charger from SparkFun:
sparkfun.com/products/726 (it’s retired but I have it!)

This charger is for single cells so I suppose it’s not wise to even try using it.

Can someone point me in the right direction for a charger for this 3A (3-cell) LiPoly battery pack?

Thanks!

you can use the Li-po Rider to charge your battery.
