When weight and weather conditions matter, this 3.2 lb. PowerFlex model provides 12AH of lithium power at about a third of the weight of an equivalent AGM battery!  
 
Flexible power connectors set this compact and highly portable 12V, DC power supply apart from the rest. Energy from this lightweight 12 AH Lithium battery can be tapped with ultra-reliable 30amp Anderson PowerPole connectors: the new standard for amateur radio and emergency response personnel. In addition to the PowerPole, you also have the use of a traditional DC cigar outlet. The sturdy nylon carrying case has 1/4" foam padding to protect your power supply, and a comfortable carrying handle on the top. Two side pockets provide storage space for AC wall-charger and accessories.  A 3-amp lithium fast charger comes with the package to keep your battery topped off, and ready for use.
