Hey so im kinda in a bit of a pickle. i was working on the razer deathadder v4 and i might have ounctured the battery and i need a replacement. i contacted the support just today but are there any ways i can find a replacement battery. i was looking into other used mouses where i can snatch the battery from and was thinking about the razer viper ultimate but the just didnt match according to my research.

Originally there’s 3.87V 306mAH battery.

Hard to find any replacement - maybe this will work as it has the same polarity / voltage and amperage: https://www.ebay.com/itm/187122703664 still it need to be soldered back to the battery controller.
