NOTE: Lithium Iron Phosphate is non-refundable! For more information please see our Return Policy. The K2 LiFePO4 battery or Lithium Iron Phosphate battery 12V 10Ah With BMS Note: The EB version is ideal for continuous draw situations up to 25 amps. PLEASE NOTE: This is an "EB" model. EB Models have a Battery Management System (BMS). BMS keeps a check on the key operational parameters during charging and discharging such as voltages, currents, internal and ambient temperature. There are three main objectives common to all Battery Management Systems Protect the cells or the battery from damage Prolong the life of the battery Maintain the battery in a state in which it can fulfil the functional requirements of the application for which it was specified. The Lithium Iron Phosphate battery is the ultimate in weight versus power technology. This is a drop in replacement for your Lead-acid battery, and will require no change to your stock charging system. It can be placed in scooters, wheelchairs, anything that uses a sealed lead acid battery. LifePO4 contains no poisonous lead, no acid, and do not create gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Lithium Iron Phosphate batteries are also extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly. Because of its light weight, safety, excellent thermal stability, good electrochemical properties and high specific capacity is this application of the material very well received. Features:• Ultra light. One fifth the weight of lead-acid batteries on average• Twice to four times the service life of lead-acid batteries• Drop-in replacement for your OEM battery• Super-fast recharge rate• No explosive gasses during charge, no lead

To open the SLA battery case requires only removing 5 screws; inside are two 12-volt, 10Ah SLA batteries. Unfortunately, these two batteries do not "drop-out" as easily as new batteries drop-in; the wire terminals were soldered to the battery terminals. Fortunately I anticipated this and also purchased Gardner Bender 20-145F 1 12-10 Gauge Yellow Female Terminal Disconnects, 16-Pack. I cut the connecting wires next to the old terminals and installed and connected the new terminals (this brand of terminals were initially too tight to fit the battery; however, by "stretching" the opening slightly with a male terminal of the same brand, they ended up fitting perfectly, and I saw no need to re-solder the connection.) An additional minor complication is that these lithium batteries are about 1/2" shorter than the SLA batteries, but I was able to make up the difference by adding a sliver of Styrofoam to the bottom of each battery.
Lithium batteries maintain a more constant voltage as they discharge; as a result, for the first time, I had close to the same power at the end of my ride up a hill as I had at the beginning. By purchasing two of these lithium batteries, plus a package of terminals, and doing a little work, I saved nearly $200 over the price of Currie's lithium battery pack, and could not be happier with the way they perform.
I cannot at this point (perhaps five trips) verify the advertised life of 2,000 cycles. If it does even half of that, the money saved on batteries (let alone bus fare or parking) and convenience of not changing batteries will be enormous.
I hope soon they will develop a drop in replacement for the U1 batteries I also use for my boat and scooter. That would be awesome.
