This is the ProTek R/C LiFe Flat Receiver Battery Pack. Lithium battery technology is evolving. With cell dimensions that fit anywhere a standard Li-Poly battery will and rapidly increasing capacity, LiFe 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 Li-Poly without the risk of pre-mature failure. Unlike Li-Poly, 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.

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 Li-Poly battery. The LiFe battery is not meant to replace the performance of a Li-Poly 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 Li-Poly 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 is 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 radios when you are done, or at least unplug them to avoid accidental over discharge if the unit is left on.

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.

I went to this pack about 5 weeks ago in my MBX6, perfect fit, cycled pack per instructions, and have had ZERO problems with this pack. I practice, run three quals, then to be on the safe side I will charge for the mains. :) excellent pack

Hey make sure your charging this on LIFE mode at 1.4 amp and 2s. You will destroy it if you charge on lipo. I run 2 of these and have excellent results. Dont discharge fully and balance charge them every once in awhile. Great product

I have 3 of these packs and have had no issues with them at all. I charge all three of them at once on my hitec multi charger with the built in balancer. I can run them all day long and they dont run out at all. Great pack for the mugen buggy.

Love this RX more regulator, no worries of over-discharge, and tons of runtime. LiFe is the future...

I'm not sure why the previous two reviews had issues with this battery, it performs great. And I'm not sure about a break-in procedure, I just charged it up and used it. I've used one battery through practice, two 7 min heats, and a 20 min main with no issues. I even bough another one just to have. These outperform any nimh packs and are better imho than li-poly because you don't need high voltage servos or a voltage regulator with them, plus deep discharging life doesn't damage the batteries like li-poly. Protek batteries are very solid.

I ran these batteries last year with no issues what so ever. Used on Hitec's 333oz servos for throttle and steering. Ran (3) 5 min qualifers and a 20 min A-Main with pratice without charging. Charged at 1C always.

Don´t buy this pack, I did the break in procedure, and it really preforms awfull, the life of this battery is low. Bad Choice to buy this. I only used it 3 times, and at the last race, on the A main it just died on the 8 min mark.

Bad expérience for 3of us 4 Time 4 races scraped to low voltage on batterie
Amb miss throtle miss :(
Lose 4 races because this battery
Drop voltage after 15- 20 min
The breaking was made
Excuse m'y english
