    maxamps 8000 Mah batteries

    Has anyone tried using Maxamps 8000 Mah LiPo's in their stock Summits? do you actually get nearly an hour run time? Is the Hyperion Charger they have in their ARTR kit A good unit? Is the kit a good deal? Thanks

    I would say that you could get close to or over one hour of run time. The Hyperion chargers are excellent. Let me just inform you that Maxamps way over chargers for their batteries IMO.

    My Opinions:

    I personally consider maxamps overpriced ... but they are waterproof.

    SMC 9000 mAh 2S 28C packs $116 ea. http://thebarnfloor.com/catalog/prod...756c0f06637367

    iCharger 208B and Meanwell 600 power supply from http://progressiverc.com

    This combo will charge both 9000 mAh packs at the same time in series or in parallel (with tap adapters) .... in the same time as one pack. I've reccomended this combo to numerous Traxxas owners/customers and they are all very happy with it.

    To ME This is the ultimate long run time short charge time combo.

    For even shorter charge times (20 minutes) the Hyperion G3 VX 2S 6500 packs from http://allerc.com can be safely charged at the full 20 amps from the 208B (5C capable!) in about 20 minutes ... and are exceptional packs .... but shorter run times.

    Good luck with your decision!

    Just buy some of the $20 hardcase ******* lipos. You can quickly RTV seal the wires coming out of the hardcase. They have plenty of power for the Summit and are cheap enough that it's not a big risk to play in the water.

    So what happens if Lipo's get wet? Because I am in Canada i worked out the difference to about $100, by the time I get items shipped. $100 might be worth it for batteries that I can run in most conditions(especially our 9 months of winter, lol), i might be able to save a couple bucks by finding a good charger locally though. thanks for all of your replies.

    I use the Hyperion Duo3 charger and LOVE it. I feel it's an excellent charger, as well.

    How wet? Running in mud and snow seem to not present any real issues while they are in the battery trays with the doors closed. You can seal the lipos up with silicone at the wire exits. You can wrap them in a balloon.

    IF you want to play sub captain that is another issue.

    My lipos have never had a problem in mud, very wet grass, or puddles of water. I can't wait for SNOW!!

    I run MaxAmps 8000's in my Summits and Revos.

    They are THE battery for the truck.

    I bought the MaxAmps 8000 Amp + Hyperion kit for the Summit and I love it plus I get great service helping me understand the way Lipo works cause I'm a newbe on all that RC electric stuff.
    I get over 45 min with a twin 775 setup and around 30 with the packs in series in my MMM Summit if it doesn't brake before that

    I have to give Maxamps credit in that they do know how to bundle a package for someone new to lipos....like pinpinz posted! Learning Lithium technology can be some what daunting at times, and the dangers of not learning it correctly are real. Maxamps also offers the only advertised "waterproof" lipo...so I give them kudos for that.

    I use Maxamps and SMC. Both have been great. Do the 9000 SMC's fit with no mod to the battery compartments? What sort of run time do you get with them?
    My lhs has one of the 4x4 Slash coming for me and I also am looking at a Summit early next year. I live near a state park and want one of these to take hiking. Mostly will be running in the low gear setting but I also want to set it up with brushless. I hope someone comes out with a water proof mosnter system. To bad the 12,000 MA's don't fit. lol

    The Summit is a very capable puller of weight. http://www.youtube.com/watch?v=U___wyYAPeY

    Add a trailer and it will haul a lot of huge packs! LOL

    I have the Triton 2 EQ AC/DC charger and like it alot. The list price is a bit high, but I used a TH discount which brought it down quite a bit.
    The built in AC supply is 100watts, so plenty of power to charge a 8000mah lipo at 1c. I charge 2 lipos for my merv in parallel at 2c, and I also charge nimh in parallel.
    When charging lipos, it will put in every last ounce of power it can, as such it has a longer charge cycle, but I pull the batteries off when the charge goes down to 0.3 amp.
    The other thing its missing is an automated lipo storage setting, so I just set the stop timer.
    I searched for many chargers, I wanted an AC charger with more than 50watts, and this was it.

    I've owned a TP 1010C for many years and it still serves me well. I guess owning a 210V balancer for it was what spurred me to learn so much about balance tap adapters ... LOL. The 610C has nice adapter boards.

    Advantage Triton if AC/DC is required!

    fastdaddycar ..... Charging NiMH in parallel is very bad (only charge NiMH in series!) Did you mean two at a time? .... or series? Just like to clarify for others!!

    Lipos can be charged in series or in parallel.

    You are right, My Bad. I charge my lipo and nimh in series. I run them in parallel to get longer runtime. Sorry for the mixup!
