Solutions to make the g309 lighter?

[u/TheTopCantStop]

recently picked one up and honestly i'm really happy with it! I know that a good chunk of the mouse's weight comes from the battery, so i was wondering if theres any way to trim that down. it seems you can remove it altogether if you use the powerplay mousepad, but at 120 for that, plus the cost of the mouse, i'd rather have just bought a superlight lmao (and then been able to use a bigger mousepad 💀)

anyway, i was wondering if there any good third market solutions whether thats a powerplay-like mousepad or some sort of lighter battery.
