Potato Battery

Potato Battery is an augment. When obtained, it increases the player's maximum energy by 3. The energy increase will be filled energy pips, also providing slight energy recovery.

It can be found as a drop from Gold Chests. It can also be found in Shops with a price of 12 Nuts.

After defeating a standard boss, there is a chance for one of the choice rewards to be a Potato Battery.

Synergies

 * Like all energy increases, Potato Battery works well with any augment which scales with maximum energy, like Juiced Reserves.
 * Enerative Plating works well with energy increases too, as it provides a bigger starting energy pool at the start of every level.
