Lipo Question

[mainesrc10]

Hey guys, new to the lipo thing and had some questions. I have a rc10t3 with a 100amp esc and 5200kv motor. Lookin to get a 2s lipo. What kind of disharge rate and size (mah), should I be lookin for? Lookin for good run times. Thanks

mah is what determines runtime. more mah, the longer it lasts. a 30c 5000mah would do you just fine.

Cool Thanks guys. I've seen some that are like 8000mah. Is there any disadvantage to a batt of that size?

[blown5.0]

The size can cause fitment issues, also the additional weight. Just get a 5000 mah it will have plenty of run time for you.

K thanks. I just tried a 2s 30c 3600 that my buddy has and it only lasted like fifteen mins, not driven hard. Is this normal and how much more run time do u think I would get out of a 5000? Thanks

That sounds about right for a 3600mah/5200kv combo. You'd probably get another 30% to 40% of run time with a 5000mah battery. Also, the higher the C rating, the quicker your battery will run down.

Will the car run slower with a smaller discharge # though?

[Charlie don't surf]

With a smaller "c" rating? Yes but only a bit unless you are racing super stock 17.5 or 21.5 you won't notice the difference- and I am running SMC Sport Max packs in Mod, they are
28c and 4500 mah, and last 15min at full race pace with either the 8.5 or 10.5-

Will the car run slower with a smaller discharge # though?

Generally, yes. Although that is why the battery would last longer.
Think of it like a bucket of water (represnting the battery) with a hole (representing the C rating) drilled into the bottom. The bigger the hole, the faster water will drain out of it, and the faster the bucket will empty.

so would u guys recommend the 30c?

[Charlie don't surf]

Racing or bashing the 30c is the middle of the road in the C rating right now, so it is nice and suitable for either- what motor are you going to run with it?

[mainesrc10]

Runnin a 5200kv with a 100amp esc.

[Charlie don't surf]

Ok, then a 30c pack will perform similar to a nice 10.5 ish, and a 65c will run like an 8.5-

[mainesrc10]

Sorry, a little new to this. What do u mean by 10.5 and 8.5?
