Bump happened to me too recently
I believe before it would still work, you still needed to take damage to restore each Battery charge
However now it no longer builds up past one charge
meaning you can never use your 1 which most of your damage and healing in half of the Victor builds
The item should be removed from Victor's item pool
It breaks his 1, and does not do anything for his 3
It only marginally helps his 2 if you already have Rapid Recharge (which seems to be very common)
