Detailed Description

This battery is K2's K2B12V10EB with the 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's 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 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. We are happy to announce that we are dealers for K2 Energy. 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 2.67lbs (3.83in x 2.53in x 5.94in). These are direct swap for your standard 7.5A/hr SLA battery.  (Terminal size F2).  

Lithium Iron Phosphate (LFP) Technology Battery

The left graph is the SLA and right is the LiFePO2 from a test we did in a Stemme on the ground at RNM. The LiFePO2 ran an extra hour and still going strong, while the SLA was below 11v. The radio was on ATIS, transponder under constant interogation, Garmin 496, Dynon D10A, and Ilec SN10B.

We have been using SLA batteries in our sailplanes for years. However they do not seem to last very long, their capacity dimensions quickly, plus they are heavy.  By the end of the flight the radio is flashing low battery, you are trying to figure out what to turn off so you can keep your IGC logger going. The fix was install another battery; this adds weight, sometimes with Non-lifting weights this is an issue, space can be a serious problem, people using a 1970s bungee from the barograph tray behind your head, the list goes on why this may be a bad idea. Personally, I want the glider as light as possible and then be able to carry the weight in water. I also want the batteries to last my 8 hour flight and not worry about them. Soaring Magazine Nov 2010 has a very nice write up on the K2 batteries, you can find it archived at

We are offering the newest batteries from K2 Energy at Wings and Wheels at lowest price. Reduce your headaches and weight for the season and switch your batteries to K2 Energy LiFePO2.

K2 Energy's K2B12V10EB battery is a 12.8V 9.6Ah battery with a built in PCM (Protection Circuit Module) which is a type of BMS (Battery Management System).  The PCM controls upper and lower voltage cut-off, short circuit protection, and balancing.  It does NOT have active communication (CAN Bus or SM Bus) for data logging or fuel gauging.

K2 Energy is the developer and manufacturer of the entire battery - the core LiFePO4 technology and PCM.  They take great pride in their product's quality, reliability, and safety and Wings and Wheels is proud to be their distributor!
