Default What C Rating Do you run in E-Buggy

Thoughts on batteries, I am running a Tekin Rx8 with 1900kv in a Mugen MBX7r ECO. I am thinking I do not need a high C rating and the 4500-5000mah is the sweet spot for weight and capacity.

Considering one of the two batteries, let me know your thoughts

5000 20c

4500 30c

Go to smcracing.net they have a great article on c ratings. There batteries are also second to none...price or performance wise.

Minimum of 40C. In the Lipo/Brushless world its truly better to have a little more than not enough.

don't they puff ? if the C rating is too low, the lipo can't stand the amperage draw. this damages the lipo . Maybe you run quite softly , can you give more infos ?

I was wondering what affordable 4s hardcase lipo ? the turnigy ones ?

You dont really want to go below 40c tbh. Anything too low will cause stress on the lipo, causing it to puff and potentially catch fire.... i run 50c and its great, but am looking at the 60c and 70c batteries. A 20c battery isnt enough, it will over draw and be dangerous.

SMC make awesome batteries for the price, so far the best batteries i have owned! And ive used Gens Ace, Intellect, venom and Thunderpower. Also for the price, im yet to find a better battery.

I concur on that statement. One might get away with 20C or 25C packs on a buggy, but going "all out" with a 1/8 scale; a 40C pack will handle the job better with "room to spare". After ruining 4 25C 2S LiPo packs in a truggy, I don't buy anything less than 40C anymore. The strain put on the batteries, from the added weight and bigger tires, was too great and excessive heat resulted in "puffed" packs; splitting open the hard cased LiPos. Since switching over to 40C rated packs, my LiPos don't get above 103F most days.

running low c rating batts will stress the speedo also as when the amp demand goes up the voltage drops so hard you start to brown out. Buy the most C and Mah you can afford. Think of the c rating as you can afford

Yes if you are running a high end brushless system especially anything 1/8 or larger it draws a ton of amps, and if your lipos cannot handle the strain they will puff even if they're hard case they will burst open and split the plastic housing.

If I'm racing 50C and up....bashing 35C if it's a great deal or regularly I bash at 40C.

Even in my 1/10 hand wound professional brushed motors on competition crawlers and 1/10 scale crawlers I run 35c-40c even for small 1000mah-1550mah 2s and 3s packs. I've had at least 5 puff on me when I ran 30C.

I don't know if I buy into that whole "maxamps true 100C" I raced head to head a Gens Ace 5000 mah 4s 50C fully charged against a Maxamps 5000 mah 100C 4s fully charged and the maxamps had a slight quicker take off, but could have been two buggies different weights, terrain, tire wear.....

Just see what everyone else on your track races.

I use a Hobbywing Xerun 150a with 1800kv motor. Been running the 20c all year as that is all I can afford at the moment. Yet to have a battery puff on me. On open tracks aswell as tight tracks.

I've bought easily 50+ of the turnigy 5000mah hardcase 20c packs and ALL have performed flawlessly. I've used them in buggy and truggy. On 1800-2600kv motors. I've never once felt like I was underpowered compared to others running high dollar high C packs.

Yesterday I got the lap record for buggy (nitro or electric) and got the fastest race time. All using 20c packs.

I run these in buggy and truggy. Powerful, durable and no puffing. I've used these for the past 3 years, retiring them or delegating them to use in my starter box after a year or so or pass them down to someone new getting into the hobby. I'm on my third set and I'll buy them again next year when its time to freshen things up.

why did you buy so many lipos ?

did you use current limiter on your esc ?
I 'm considering those lipos for the hardcase. I use softpacks nanotechs high C right now and they get a bit hot.

If you guys run 20C might as well stock up on 15C too then. No way can you keep up with an average 40-60C racing designed lipo pack.

I'm also willing to bet your lipo individual cells never balance correctly due to poorly built lipo trash. But it's your pensive toy....I'm just saying middle of the way hard cased lipos are the way to go and they last much longer with better built cells.

If your electronics are high end which now I realize are not...then cheap low C rated lipos are fine. Put that same setup on any Tekin 1/8 truggy or buggy setup your lipos will smoke!!

Probably your Rc too...not worth skimping a few bucks on lipos when it's basically dynamite in your rig!!
