TPI PowerPack is an external battery   with built-in high capacity Polymer Li-Ion battery allowing for your robotic instrument to run extended period of time without the hustle of heavy and bulky batteries. The 15,000 mah Li-Po battery is nearly 3 times higher capacity than original Trimble batteries plus it's compact size and light weight makes it a perfect alternative for long lasting external option. Lithium-Poly rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity gel polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature. The LED battery indicator allows you to see exactly how much battery power is left. Metal clip allows for easy attachment of the battery to any tripod . Size:  6.5" X 3.6" X 2.5", Weight: 1.8 lbs, 12 volt, 15,000 mah.
