These servers are very unique. We need them despite the battery issue. If you can remove the battery and give us alternate powering options I want to buy one to test, then get more later if it works. My guess is that a portable UPS would run this thing for a long time (an external battery is a better idea). The WRTD-303N needs 12 volts and 2 amps, right? Amazon has a portable Kitbox SK313T battery pack 7800mAH with 12V 2A for less than $50! That would run this for 10 hours!
