View Full Version : Average Battery life
phaseout

Hello, i'm new to the hobby and started by purchasing a Savage X. I'm hating it so far and regretting getting into nitro without further research. Too hard to start. too much money. Too loud.
I really want to sell my savage and get into electric and purchase either an e-zilla or an e-maxx.
I wanted to ask what the battery life is on average if I was to run a couple of 3300's. I don't plan to race much or keep the thing on full throttle for the entire charge. I just wanted to know if there is a way to squeeze 45 minutes to an hour out of an electric truck before recharging.
Thank you

Hang in there! The first time is always frustrating for everyone. Don't be afraid to tinker around with your truck, its the best way to learn, coupled with this forum, some magazines, and the internet, you'll eventually get the idea behind this whole nitro deal.
A single 3300 pack should give you about 10mins of good full throttle run with a 19 turn motor. But its really hard to guess.
The lower the motor turn the less the runtime will be.
phaseout: I'm in complete agreement with you about nitro, I've seen alot of beginners turned off to the whole hobby due to the frustration they encountered with nitro engines. The Savage is a great truck though, sorry it isn't working out for you. I've owned an EMaxx since they first came out and have raced it AND bashed it everywhere I go. To answer your question, I think it'd be very hard to get 45 minutes of runtime. Even if you were to gear it down (put smaller pinion gears on the motors) I'd say the best you can hope for is 15-20 minutes with 3300mah batteries. You will get more with the higher 4500mah batteries, but you risk overheating your motors. They make finned motor heatsinks that help cool motors, and I highly recommend them. Get an extra set of batteries and rock on when the first set run down, but keep an eye (or finger) on how hot the motors get. If you can't hold your finger on them, it's time to let them cool down. HAVE FUN!!

Actual runtime will vary where mod oval can have issues making a minute race to some reporting 20 minutes+ of runtime. Lifespan also varies from as little as 1 year to 3 years+/-. If have some that were purchase back in Oct 2002 that were used in competitive racing - pack still charge good but with the high voltage cells like IB3800 the GP3300 aren't used much except for practicing - some packs do have a noticeable decline in runtime/performance but might be okay for bashing.
Don't give up on Nitro just yet, each type has it's plus and minus.
Nitro cars today are much easier to use in most cases that than than they years ago. Electric have some short falls too - motor maintenance, proper gearing (may need several pinion gears), plus the other equipment that you may not have already.

You can get a 12000 mah pack if you go li-po and you could get an hour easily with the right setup but that would cost you big time and you'd definately need brushless to handle that kind of non-stop running.
If you want runtime I reccomend going brushless and getting a few packs. With brushless, as long as it's not over heating you can run as many packs back to back as you want. Sure you have to stop and change packs after 10-15 minutes but with nitro you'd have to refuel in that amout of time as well.
