I recall seeing this solution a while back on JKKMobile but Paul from MoDaCo has now got one for testing. Its a 47Wh battery pack for the HTC Shift from Mugen which should allow about 5hrs online time thus solving one of the HTC Shift’s biggest problems. It’s a tidy solution but at nearly $240, it’s a huge amount to pay for 5 hrs of computing time.
Paul is doing further testing and will report back on performance soon.
the day this gets a decent cpu it will be a no-brainer (with this new battery, of course)
Here is alink to the batteries, if you are interested: http://www.mugen-power-batteries.com/htc/htc-shift-x9500.html
