K2 Energy 12V 11.1Ah Lithium Iron Battery
General Description
K2 Energy 12V 11AHR Lithium Ion Battery - If you’re searching for the most innovative and dependable batteries in the world, look no further than K2 Energy. Utilizing the latest Lithium Ion Phosphate technology, they are able to produce incredibly effective energy solutions for use in medical, transportation and military applications.
They strive to create energy products that outperform traditional batteries in performance, safety, power and environmental benefits. Producing both energy and power battery cells, modules and systems, we are certain that their products will stand up to whatever challenge you may be facing and will last for years to come.
This is K2's K2B12V11EB with built-in Protection Circuit Model (PCM). A “PCM” is a Protection Circuit Module, that in its very simplest form controls the upper and lower voltage cut-off and has short circuit protection. K2 batteries also include balancing. K2 conforms to the University of Texas' patent requiring the highest quality raw materials. There are cheaper offshore choices which bypass quality and safety standards… BE CAREFUL! K2 Energy is known for; superior cycle life, reliability, quality and safety.
Lithium Iron Phosphate (LFP) is a special kind of lithium battery that addresses the 4 major issues with current lithium technologies: Safety, Life, Power, and Environmental Friendliness. The discharge of a LiFePO4 stays at a higher voltage. You see a better working capacity than the SLA 12AH batteries, however, these are light at 2.87 lbs (3.83in x 2.53in x 5.94in). These are direct swaps for your standard 7.5A/hr SLA battery. (Terminal size F2).
K2 Lithium Ion™ battery technology delivers high power and energy density without compromising safety.
- Safety – K2 Lithium Ion does not experience thermal runaway.
- Long Life – K2 Lithium Ion has low capacity loss and low impedance growth.
- Lighter, Smaller – K2 Lithium Ion is light weight and up to 1/3 the size of conventional lead acid batteries.
K2 Lithium Ion can be cycled to 100% depth of discharge allowing our cells, batteries and systems to meet, often exceeding energy needs and even avoiding the need for redundant capacity.
Wings & Wheels is proud to be a K2 Energy dealer.
