Extended Battery Mv reading

[byrds8]

I was wondering what should the Mv reading be at full charge on the ext battery? Mine is like 4200. I only ask because I thought someone once said that their stock battery was around that. Cant remember where I found that though to look again for myself. Thanks

4200 is fine; all LiPo batteries have a max charge of about 4200mV.

Ok thanks. I didnt know they all had the same voltage. I thought since it was an extended battery it would have more than stock. Mine has a weird drain on it where sometimes it would last longer than others with the same things running so figured maybe that had something to do with it.
