It is nice to have charged batteries around for a few minutes of fun or some testing. My LiPo's almost always have a charge that would be safe to use for at least a short run. I've had a set of 6k Thunder Powers for almost 2 years now. They charge like new and perform like new.

Craps

The manufacturer's only recommend storing a li-po around 1/2 capacity incase there is an accident damage while transporting to the race track for example and the battery is punctured in an automobile accident, in other words the less energy the better incase of accident.

With that being said, I always keep mine fully charged for the last 4 years with no problems.

Great batteries and they may have came along hopefully just in time to save electric racing!!!!

Brushless and li-pos will bring back alot who went to gas for various reasons! I already see it happening with those that can't afford the expense of gas 1/8th scale racing along with the huge gas maintence factor too!

Let the revolution begin!

i think that this is ausome and that we should try to make this for all club racing!

Here's some info I found on the benefits of storing at different temps and % charged.

Stored 6 8000 mah li-pos in a plastic battery box bought at the hobby shop! No problem!

This class is a blast and is great for getting newcomers into the hobby. All it takes is a bl rustler or xxx-t and a 6k mah lipo which easily rivals the cost of a rtr nitro truck. Not to mention trucks are actually starting to become durable. The xxx-cr & the tweaked t-4 are both tough as nails. The large cock pit in a truck is also perfect for keeping electronics cool.

so is that two packs wired parrallel, and if so where do you get the packs from for $80 a piece for 6400 mah is smokin, and does that effectively give you 12,800 mah run time .

by the way i know thut my spelling aint do great === but then again neither is my driving... lol

Personally I pick up a dewalt 36 volt battery, it is made with 10 a123 cells and then I use 6 of them to build my packs. I use a 6.6volt 6900 mah pack which works perfect w/ a little more motor for off road. I like the a123 cells because you can charge up the pack in about 40 minutes from dead to full. If you want to run lipos then heres a link for 6400s @ $80 a pack.

You have to scroll down a little. I supose if you taped two togather on top of each other you could run a 12.8ah pack if you wanted to.

Depending on what Novak motor you go with will determine runtime. I have seen 10.5 motors go for over 20 minutes on a 4800 Orion Li-po and 5.5 motors will be real close to making 30 minutes with an 8000 MaxAmps li-po both on an 1/8th scale size big track with big jumps. I prefer the MaxAmps 8000 with a Novak 7.5 that is a real good all around motor that is not too much power for a 2wd truck.

Thunder Power also makes an 8000 mah battery that fits in the truck. TP8000-2S4P id the number.

Good luck!

Note: I get a little over 40 minutes of run time with the 7.5 Novak motor and 8000 mah MaxAmp battery in my T-4.

Does anyone know if Novak 6.5 on a Trakpower 4900 will have a runtime of over 20 minutes?

Probably not; Thats the exact combo I use in my T4 (Noak 6.5 + 4900 Trakpower) and it usually takes around 1750 mah to repeak after a 6 minute main. Based upon that, I would expect maybe 15 minutes of run time.

I think you would need at least 6000 mah with the 6.5 to run 20 minutes.

You should be able to make 20 minutes w/ a 7.5 motor though. I have heard of people running for 40+ minutes on a huge track w/ an 8k mah pack & a 7.5.

Craps

I seen a 10.5 in a truck finish one of our 20 minute mains with only a 4800 Orion li-po battery.

I have ran 42 minutes with a 7.5 and an 8000 mah battery.

There is a local indoor track where guys get 30 minutes w/ a 10.5 and orion lipo. I'm sure from seeing that caps gets 40 minutes w/ an 8k mah pack and a 7.5 that you could make 20 minutes w/ a 4900 mah pack.
