Hi all,
I am looking at http://www.sparkfun.com/products/10472 (http://www.sparkfun.com/products/10472) which is a Li-ion polymer dual cell battery with 7.4 V and 1000 mAh. This suits me as I require a high discharge rate, at least 7 V and light weight
However, the charger for it is http://www.sparkfun.com/products/10473 (http://www.sparkfun.com/products/10473) and costs $32 which is a bit steep.
Does anyone know of a cheaper charger for a dual-cell Li-polymer?
Thanks a lot!

$32 for charger and balancer able to charge cells of different chemistries is not much at all :)

I'm using it on my robot to power the Arduino & other electronics. It has onboard charging electronics so no need for a special charger.
