Re: Ambitious battery mod in need of a battery helpdesk
The only problem is that I purchased the external battery via an online auction, and as a result, I have no idea how many charge cycles it has previously been through. If the capacity is much smaller than the battery that is already installed, then this won't work since the packs will quickly go out...
