G2 Black and Backfire Galaxy Battery Update

We have recently upgraded the battery charging wire plug to be more water-resistant.
In addition, instead of using the plastic shrink wrap, we are now using a silicon case to put the battery in and using water-resistant glue to fully seal it.

So the water is much less likely to get into the cells or BMS anymore.

    Does this battery provide better mileage on G2 or just better water resistance
