Detailed Description

K2 Energy® Lithium Ion Battery

K2 Energy Lithium Ion Battery

General Description

If you’re searching for the most innovative and dependable batteries, cells and systems 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 K2B12V10EB 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 LiFePO2 stays at a higher voltage. You see a better working capacity than the SLA 12AH batteries, however these are light at 2.87lbs (3.83in x 2.53in x 5.94in). These are direct swap 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. They experience no thermal runaway, have low capacity loss and impedance growth, are light weight and up to 1/3 the size of conventional lead acid batteries. They 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.


K2 Energy® Battery Benefits
