Frequently Asked Questions
Does a bigger battery change how the controller feels?
It adds some weight, which most people do not notice in play. Everything else on the Battle Beaver PS5 works as before.
Does it charge with the same cable?
Yes, through the same USB-C port. A larger battery takes longer to fill.
Can I get other Battle Beaver PS5 repairs done at the same time?
Yes. Tick every fix you need on this page and they are done in one visit. The dearest one is full price and every extra one in the same order is 10% off. Popular add-ons on the Battle Beaver PS5 include full button & trigger restore, gulikit 720 tmr tension-adjustable sticks, battery replacement.
