|  MaxAmps.com Green Series Life 4500 6.6V Battery Pack - New cell technology! New pack choice for scalers and most other 1/10th scale set-ups. MaxAmps.com brings you the exclusive “Green Series” LiFePo4 battery packs. These new “life” packs will not catch fire or explode with overcharge. In addition to being safer than LiPos, they are more robust. The new 4500mah 6.6V pack can be charged using our Hyperion line of chargers under the LiFePo4/A123 setting. • Perfect fit in all standard rc car battery trays • Same flat format as lipos(136mm x 45mm X 26mm) • Low-maintenance and user-friendly • Inherently safe technology • Low voltage cutoff is not required • 1000+ usable cycles • 5 year 1000 cycle warranty available • Environmentally friendly • Water-sealed for all-weather protection • Up to 60C discharge rating(1700+ surge watts) • Up to 15C charge rate(67 amps) hard cased will be an option as well The 2S2P 4500 pack retails for $119.99 Pack weight 75 grams per cell and figure 15 grams for plugs and wire. Pack total weight at @ 315 grams A 2S 2250 pack will also be available for around $60.00 For more info or to order please call 1-888-654-4450 They will be on the site in the next couple of days, a link will be posted then. I ran this pack all last week in final testing in my Traxxas Slash powered with a CC Mamba Max and a 5700 motor. The gearing pulls about 67 amps peak and was giving me 15 minutes of non-stop run time on the test track. The pack was charged at 10 amps on my Hyperion DUO and took 30 minutes to put in 4500 mAh. Pack temp after charge was 84 degrees. Pack temp out of the Slash after 15 minutes of non-stop running was never more than 90 degrees. I had the LVC set for 2.0 volts per cell, Slash stops rolling at 4.8 volts so LVC's are not needed. Power is that of a 6 cell Nimh pack and real close to a 2S Li-Po. This is a great beginners pack. Good power, good run times, short charge time, and best of all really safe. Jason |

|  I know a123 cells have been around for a while, but not so much for rc. Is this going to be the future of the hobby? Will you have a 3s available soon and dimension? |

| We will have a 2250 series made from these same cells and the 2S2P series, meaning we will have 3S2P, 4S2P and so on. For sizes as of now you can use the dimensions of the 2P 6500 packs they are pretty much the same as the 2P 4500's. Jason |

| Are these prismatic pouch cells or hard cased cells? Great charge specs, now to find a charger to pump them full  |

| Please see the original post, Your charger must be able to deal with A123/LiFe-Po cells. -J |

| Do these new batteries come in smaller physical size or just a typical stick pack size? I just want to be able to put these next to my servo on my ax-10. |

| Right now only in the same foot print as a 6 cell shot gun pack. We are working on a smaller size hoping to get in the range of our current 2200 Li-Po or our 1550 Li-Po but still have a decent capacity. Jason |

| Damn, shame that they won't charge on a LiPo profile. I guess the lower voltage per cell would be the problem there  |
