Hi all,

I bought a 3.7v 1200mAh lithium polymer battery with inbuilt protection circuit to replace the standard 300mah one, I didnt use the orginals battery circuit that stops overcharging as it has its own so ive just connected red and black to the mainboard from the battery. once fully charged to 100% it shows 15hrs left why?, it should be showing 60 hours?. Any help apreciated thanks.

The battery life remaining is estimated from the stock battery capacity and known runtime, its not actually measured from the battery you have installed.  If you change the battery, you'd have to change the battery capacity listed before the estimated runtime will be different.

Hey Ellis, where did you pick up that battery? I've just begun looking for a replacement for the one that burst open my Clip Zip.

Its about the size of the back clip and wont fit inside so ill be modding the case a bit.
