Battle Energy

 is a new addition in Bloons Tower Defense Battles. Every time a battle has been completed, both players loose 5 Battle Energy, win or loose. If the player's Battle Energy goes below 5, the player must wait until it recharges. Every 12 minutes, 1 Battle Energy gets replenished.

Trivia

 * If the opponent disconnects before the battle has started, the 5 energy gets refunded back.
 * There are many max-energy boosting and replenishing items in the store.
