A Main Hobbies Announces ProTek R/C 2S "Supreme Power" LiFe 35C Hard Case Battery Pack (6.6V/4000mAh, Pin Style)Chico, California, March 15, 2010 – A Main Hobbies today announced a ProTek R/C brand LiFePO4 2-cell “Supreme Power” hard case battery pack with 4000mAh capacity and a true 35C constant discharge rate. 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.
This pack includes heavy duty bullet connectors and a balance charge lead that you can solder onto the wire of your choice. The bullet connectors also feature side cut-outs for soldering on wires to fit in tight areas or in cars with low upper deck heights.
These battery packs are built using a hard plastic pack that is required for use at ROAR sanctioned tracks and events. The packs are thin enough to fit into all touring cars and off-road vehicles, and with the humps on the bottom will be secure in vehicles designed for side by side NiMH race packs.
These ProTek R/C battery packs can be used in any application where you need 6-cell NiMH stick or race packs, such as 1/10th scale electric touring cars or 2wd and 4wd off-road vehicles. These packs are significantly lighter when compared to regular NiMH race packs. This makes the overall vehicle weight lighter for significantly improved acceleration.
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.
NOTE: Brand new LiFePO4 batteries have been found to fail prematurely if they are deep discharged below 3.26V per cell (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 3.26V per cell during the break in period or below 2.5V per cell after break in.
3) You must not charge this LiFe battery pack at rates higher than 1C.
4) Read the instructions carefully before operating this battery.
The batteries will sell with a street price of $79.99. But don’t be fooled by the low price! These batteries perform as good as or better than the most popular name brand batteries on the market today.
