help choosing perfect retropi platform

[NeonTrooper]

I learned about using the raspberry pi zero for retropie a while ago and the fact that you can fit a gaming device in the middle of your palm is really just amazing! I'm having trouble choosing which system to buy, as I do not have a soldering kit. I was thinking about the tinypi pro because it didn't require soldering, but the fact that it has only one hour of battery was a deal breaker for me.I'm looking for a system with 2-3 hours of battery or more and a price range of $45-$85, but $50-$65 would better fit my savings. suggestions???
