RG353V turning off and unresponsive while under load

I got a used 353V running ArkOS and stock Android. I put a fresh copy of ArkOS on after receiving it using non "Anbernic" SD cards. When under load, like I was trying to install the Shredders Revenge port, the screen goes black and the device becomes unresponsive. The only way to get it back is to pop the back off and unplug the battery for a few seconds. It happens on the Android side as well, but not as often, which leads me to think it's either the battery or some other piece of hardware, not software related. Any ideas? It would be greatly appreciated if you've had this issue before and have an answer. Thanks everyone.
