    I use pro-match 7.2v 4600's in my Emaxx and get about 20 min run time. There would more than likely be a power difference between the pro-match and dtx batteries. Run time would probably be the same. Pro-Match also offers 8.4 5000mah nimhs though. With out going lipo, I don't see you getting much more run time, gearing down would help the run time but wouldn't make a huge difference. http://www.promatchracing.com/

    thanks for the reply,

    so that means charge times of almost 2 hrs if you have a 5Amp charger... but just an hour if you have a 10 amp charger... something to keep in mind.

    The owner is "John the battery guy"

    he has the Tenergy cells he custom makes his packs with. I use 5000Mah Nimh in my kids' Summits,

    45 to an hour in low gear, easy.

    HIS SERVICE IS UNBELIEVABLE!!!

    I had a Tenergy pack from another vendor that had a bad cell, I sent it to him and he fixed it, balanced it and charged it for free since I bought 4 packs from him this week. I cant say he will do that for every body, but WOW!!!

    i will always buy my kids' NIMHs from him from now on. Tell him Jim from Pa sent ya! I had a long BS session with him on the phone, nice guy!

    I like to support the local guy, I also use the SMC lipos from up here in PA too... great packs...good deals are not always found on EBAY!!
