Providing this much light requires a lot of energy. Your choice of BatPak comes down to two factors. How much light do you want or need, and how long do you need it? More light and longer run times require more energy and hence a larger BatPak. So we offer three sizes of BatPaks.
In this video, Ben Light introduces the various components supporting the RA light including the three BatPaks.
The RA light has 20 levels of brightness so you can manage your power consumption to meet your needs. This table lists how long the batteries will last starting from a full charge. The numbers are for a single RA at a corresponding brightness. To get battery life for two RA running at the same brightness, divide the number of hours by two.

To keep it simple, we sized the BatPaks with their total energy corresponding to their model number. The BatPak 2 lasts twice as long as the BatPak 1 and then of course the BatPak 3 lasts 3 times as long as the BatPak 1.
