This is a ProTek R/C 1800mAh LiFe Hump Receiver Battery Pack. Lithium battery technology is evolving. With cell dimensions that fit anywhere a standard Li-Poly battery will and rapidly increasing capacity, LiFePO4 chemistry will soon set the standard that all others are judged by. With the ability to deliver 1000+ usable cycles, and a life span up to 4 times longer than Li-Poly batteries (when cycled under the same discharge conditions), these batteries offer the user an excellent balance of performance and value. LiFe batteries are more durable than Li-Poly and are able to handle a higher level of abuse when compared to LiPo without the risk of pre-mature failure. Unlike LiPo, LiFe cells can be stored in a fully charged state with little to no loss in stored power, and can be discharged deeper with less risk of damage to the cells. Most importantly, LiFe batteries are SAFE! There is no risk of combustion! LiFe cells will not catch fire or explode when over charged, or after a deep discharge.

This battery is a direct fit in Kyosho and Tekno 1/8 scale battery boxes.

What about the voltage?
A 2 Cell LiFe battery produces 6.6 volts nominal, which is almost a full volt less than a 2 Cell LiPo battery. The LiFe battery is not meant to replace the performance of a Li-Po battery, it is simply another option. LiFe offers the user a battery with a good discharge curve that is better than that of a NiMH battery, but without the risk of damage or fire that exists when a LiPo battery is abused. Additionally, when used as a receiver pack, a LiFe battery eliminates the need for a voltage regulator, which reduces the risk of failure by eliminating a component that could potentially fail. 

NOTE: Brand new LiFePO4 batteries have been found to fail prematurely if they are deep discharged below 33% capacity too early. A break-in period of 20 cycles is currently recommended. While testing has shown that this battery can be charged at up to 3C rates, it recommended that this battery not be charged at rates higher than 1C to maximize the lifespan of the battery. Additionally, LiFe batteries should not be discharged below 2.5V per cell to avoid pre-mature failure and maximize battery life span.

We also recommend you REMOVE the batteries from your cars, or at least unplug them to avoid accidental over discharge if the unit is left on.

IMPORTANT:
1) You will need a LiFe specific charger to charge the pack (NiMH, NiCD or Li-Poly only chargers WILL NOT WORK!)
2) You must not discharge the LiFe battery pack below 33% capacity during the break in period or below 2.5V per cell after break in.
3) It is not recommended that you charge this LiFe battery pack at amp rates higher than 1C.
4) Read the instructions carefully before operating this battery.

Please be aware that this battery has a discharge rate of 3C. They do not list this in the specification on the website. May not be suitable for some applications.

Exactly as described and fast shipping. Good quality item ,would recommend.

I will say that I gave it a 4 star simply because it was ever so slightly larger than expected which made fitting it in my nitro RS4 more of a task than I would've preffered. Overall though great product. Slightly larger than a pack for 4 AAs.

Excellent working battery. So much better than Nimh but the size is a bummer.
It's great for the cars it will fit in but too big for some of my cars and I've had to do modifications to get it to fit and just barely.
They could make a 1600 or 1500 Mah version that's a little smaller, still be way better than the Nimh 1600, and fit in any of my cars.
Why won't they do that?

I'm sure its a good battery but why so much $$? I got a 1700mah 20c LiFe pack elsewhere for $10

Anyone fit this in a Losi 8ight buggy or truggy? If so using flat battery cover or hump cover? Dremeling required?
