# of Batteries at regional

[Ken Leung]

After checking up the rules and Q&A, I found out that you are in fact not limited to the 2 batteries shipped with the kit of parts this year:

<R46> The only legal main source of electrical energy on the robot is one of the two 12v DC non-spillable lead acid batteries provided in the Kit of Parts, or a spare of the same part number. The 7.2v “backup” battery is considered an integral part of the Robot Controller, and may not be used for any other purpose. The only 12V battery that may be used on your robot during competition (Friday and Saturday) is the Exide model ES18-12. (Additional ES18-12 batteries may be purchased through your local Exide supplier.) You may use other equivalent 12V batteries during Thursday practice rounds.

(Ricky already quoted this rule)

and a clarification from the Q&A:

Q: Please be exact. Are teams allowed to purchase additional batteries as the rules say and use these identical batteries during competition or are teams required to "ONLY USE SHIPPED THE KIT battery? Recharge time and cycle life is limited.

A: You may purchase identical batteries and use them.
