Battle Energy

“	Governs how many matches can be played back-to-back. Recharges 1 Energy every 12:00 minutes.	”
	^{~ BTDB Flash Description}

Battle Energy () is a feature in Bloons Tower Defense Battles. It is used to control the amount of matches or items(powers for example) the player can play within a time. The player spend Battle Energy to use the Spy Ability or get an extra tower. Every 12 minutes, 1 is replenished, even when the game is closed.

Differences between Flash and Mobile

Energy is no longer used to control matches, meaning the player can play as much matches as they like.

Energy is used to get a random 4th tower for a game(even if that tower isn't unlocked) rather than a 5th tower of the player's choice that they unlocked already.

(When spying was still a feature)Spy ability energy cost reduced (6 > 1)

Spy ability removed.

Battle Energy is used for powers.
