^^ Not trying to pick a fight here, but it's damn hard to find a lot of this info. I have seen this explanation many times here myself, but there is a LOT of info to sift through. Even if you search, you get dozens of results you have to read through.

If you're sick of "having" to explain it, don't. No one made you. THere are a LOT of people on here who can't wait to help out those that are just starting out, and see it as a priveledge, not a burden, to help others with queries or problems.

NO offence intended.

Rant over.

Sorry it came across wrong, YGPM

ok so from what i am reading here a 20c lipo should be more than enough for a 20t brushed motor? Im on a budget and don't want to spend more than i have to. But at the same time I want to make sure i have enough.
Thanks

well you get what you pay for. if you buy a 50$ china made pack that most of us havent heard of its probably bad. what lipo are you looking at?

20C is fine for a 20T brushed. the higher the C the more amps the battery can handle coming out of it = Lower internal resistance (IR)

Here's an interesting observation: Yesterday a formerly "sponsored" racer showed up at the track sporting the latest gear he had; TC3, and 3000mah NiMHpacks. Okay, he hasn't raced in 5 years or so. Anyway I lend him a CORE 3250 pack to use in one qualifier and a Trinity IP 3800 25+C pack for another with a 19T motor and Novak Cyclone ESC. His comment, "Wow, the power was consistent from start to finish unlike NiMH." Good so far, then I asked him which pack felt like it had more punch. His answer was that he couldn't tell the difference and his lap times backed that up. He also tried someone else's SMC 4800 with the same results.

This is purely empirical but will tend to support the concept that it is more perception than reallity.

Now I'm not saying go out and buy cheap packs but it seems that the mid-priced stuff works.

I was looking at a venom 20c 3200ma 2s. I am assuming that this should be a decent battery. Venom is a well known name.

I suggest these if you're after good running, strong 3200s.

Yeah Racing 3200s. AND they are ROAR approved too :P

i have two of them (and a YR 3600) and they all run great great great. No issues, even after accidentally running them too low a voltage (the 3600 went down to 5.5v and one of the 3200s didnt even register to my charger) but they both got brought back to life with some additional help and have been running with zero isses and plenty of power. Cant beat it for the price, really.


a friend of mine runs them in mod too, they run perfectly fine. I ran them in mod for a bit too. No problems there

Just IMO but I haven't found anything from Venom worth while. I don't know about thier lipos but I'm not gonna find out either.

I have a couple of the Venom 5000s and they seem to be a good pack, zero issue in over a year. They don't seem to have quite the punch of my Reedys or Maxamps though.

Not tryin' to hate on Venom (too much) but that's the kind of thing I'm talking about.

Thanks for the info. I think I will stray away from the venom pack and go with one of the other ones mentioned.

One pretty important thing is missing from this thread though

The C rating by itself is not an indicator of how well the battery will perform in a specific application. You multiple the C rating by the packs amp capacity to get the amperage it can deliver.

Thus, a 20c 5000 mAh battery can deliver 100 amps. A 25c 4000 mAh will also deliver 100 amps. As would a 30c 3300 mAh battery...

The C rating can be used as a general guide to the cell's quality, but you can't say "a 20c pack is fine for that". A 20c 6000mAh will deliver substantially better than a 20c 3000mAh for example - up to twice the amps.

so by going to a hight C rating I can go with a smaller mAh battery and get the same out put? I will just have shorter run time due to the lower mAh correct.

Higher C ratings (that have been proven and tested) usually means better cells too which in turn means the pack will have a much longer, useful life.
