opove M3 Pro Massage Gun Rechargeable & Replaceable Battery, Original

The battery lasts for a long time and recharges very quickly.

It’s a 25volt battery. It works in my hypervolt just fine. The issue I have is that the 12volt charger that came with my original hypervolt doesn’t fit and wouldn’t be to able anyways because of the voltage. Maybe it would be great if it was in the description. Now I have a battery and no way to charge it. I would not have ordered this if I knew it did not come with the charger. Now I’m looking on Amazon for a charger. SMH

So happy we have a new battery because the hypervolt is an everyday must in our house. Helps with the blood flow in our tight muscles after long workouts

Updated - After the issue below, the company contacted me and replaced my massage gun with a new one.I bought this battery to replace the one in my current massage gun. After putting it in, and starting it up, it sparked and started to smoke. Now I don't have a massage gun! Very disappointed!

Use before bed And have no soreness in the morning. Able to workout at 5:45am everyday because of it!

Works great now I can keep one charger and quickly swap it

Would not work would not charger with the charger I had order a new charger still wouldn’t work!! Highly piss off

This battery must be product specific. It’s not a generic battery that you can just use coz it doesn’t fit my massager-too big. The box container adhesive seal is broken - gives you an impression of possibly an open box item. Also noticed some minor scratch. Which is not a big deal for me. But the deal breaker was it doesn’t fit my massager. No point in keeping it. Returned item same day it was delivered.
