This new battery represents a tremendous leap in technology from our older Pelican lead acid batteries. This new rechargeable battery pack is rated at 12.8 volts and 20 amp hours. It may be used with our PowerMax Ultra, PowerStar (rack mount version) or our PowerStar LiFE power distribution products. It can also be used with most stand alone lead acid battery chargers. This new Pelican LiFE battery is built in a rugged Pelican 1150 case that measures only 9.25” x 7.5” x 4.375” (23.5cm x 19cm x 11cm). The entire product weighs just 7.25lbs (3.3Kg). Our design uses special cells allowing higher than normal charge and discharge rates. The Pelican LiFE battery is rated at up to 25 amps of discharge or charge current. Internally it contains active electronics to protect the cells against deep discharge, overcharging, excessive high discharge rates (short circuit) and excessive charging rates. In addition, the electronics provide cell balancing while charging for longer cell life. We now include a built in Battery Volt Meter and Output Current Meter to provide you with useful information. Additionally, we have extended the warranty on the LiFE cells to a full two years!
