40V Lithium-ion Battery - Flex Series

  Rev up your Redback tools with batteries made especially for them.   The EP20, EP40, and EP60 can power the Redback's various 40V power tools. And each battery lengthens your tool's run time and efficiency depending on the capacity. Redback's battery packs come in 3 options - 2.0Ah, 4.0Ah, and 6.0Ah for you to choose from.   There are three identifiable differences between the 40V battery series. Each of them has its battery capacity printed on one side, a color marker, and weight difference. With the color marker, the 2.0Ah has gray, 4.0Ah has orange, and 6.0Ah has black. Their weights vary too, 1.98 lbs. (0.9 kg) for 2.0Ah, 2.86lbs (1.30 kg) for 4.0Ah, and 3.85 lbs. (1.75 kg) for 6.0Ah. Not just that, but these batteries also have a built-in indicator that allows you to check how much power it has left while in use or even while stored.   Redback power tools can run for an average runtime of 20 to 120 minutes when used with EP20 (2.0Ah), 50 to 240 minutes when used with EP40 (4.0Ah
