Frequently Asked Questions

If you’re comfortable with basic electronics, the included screwdriver and clear instructions make it manageable. However, mishandling lithium polymer batteries can be hazardous, so proceed with caution and consult online resources if unsure.
These offer a significant capacity boost over the originals, translating to noticeably longer playtime between charges. Expect roughly 20-30% more runtime, depending on usage.
These batteries are designed exclusively for the XVive U4 system due to the proprietary connector and voltage requirements. Attempting to use them in other devices could damage both the batteries and the device.
