Li-ion Battery Pack

Available as either 8300 or 22400 mAh at 12v. Note that if you order these on their own, there is an extra shipping cost of £15 due to shipping regulations. If you order with the equipment they're to be used with, you can save this cost.
 
Note that on the 8300 mAh unit the yellow power output is 9v and the black one 12v, but on the 22400 mAh unit the yellow power output is 12v and the black one is 24v. Don't get them mixed up!
