Default Batteries for 8ight Buggy

I am going to purchase a few extra batteries. Could use some help deciphering all the terms though.

I want a really fast setup so curious what the best biggest sorta battery I can put in the car?

It has the tekin rx8 and 1950 motor in it.


I know that 1s,2s,3s,4s etc just means how many cells the battery is but curious what the C is for, 25,35,60c and so on?

Can my car handle a 5s battery if so what is a good reccomendation, or should I stick with the 4s and go with a 60c or maybe a 35c?


Any help would be much appreciate, again I want a good battery that will make my car super fast.

When you say super fast are you talking for racing? or speed runs?

Well I am in Afghan right now so we are basically just gonna race around the big open dirt area. So dunno if that helps just want the best batts I can buy that will provide the fastest setup. Open to comments or suggestions.


Currently the buggy is coming with a venom 35c and 25c 5000mah 4s, but was thinking of picking up 2 more batteries.

You might be better going with 5S for speed runs (large open areas) with that motor. With the 4S you'll be able to gear it up to go a bit faster but you'll be working your batteries much harder. The packs you got should be fine but i'd be careful with the 25C's, 30C and 35C are good but 40C would be even better, especially if your pushing for higher speeds.

Ok, thanks for the advice.

The 25c that comes with it, when you say watch out for the 25 and or the 35c can I run the car with those or is that bad? What is the C for anyway?


I found 2 types of batteries on ebay looking to buy 2 which ones should I go with.


I found some Zippy Flightmax 5000mah 18.5v 5S they are 45C discharge, 55C constant lipos they are 88$ bucks each.


Second choice is:

Venom doesn't make anything over 35c in 5s, at least on ebay so only other choice I can see is Thunder Power 5s 5000mah G6 Pro 45c 18.5v and they run 189$ a battery...

Third I did find some Venoms, they are 50C 5000mah 5s 18.5v and they are 120 a battery.



Thoughts, Comments?

C is the discharge rating. ie the rate at which it can be drained with out causing damage. The higher the C rating the higher the discharge capability.

a 5000mah pack with a 25C rating can deliver 125 amps.

5000mah = 5amps x 25C = 125 amps

Every set up (motor / esc / gearing / car / battery) is different but for most 1/8 scale buggies i would recommend 120 amps as a minimum but 150 would be safer for what it sounds like you'll be doing with it.

The 5000 25C will work and when i say be careful i just mean dont go running the car flat out speed run after speed run with that pack, it will be working very hard and pushing it that close to its limits may cause damage to the pack and / or your esc.

I run Turnigy's and have never had any issues and you can get 5000 4S packs for $52 plus postage (but Hobbyking products are cheaper to ship here to Australia and not sure what it would cost to the states???). Lots of people are praising the Gens Ace packs lately and they seem to be pretty good value. From memory they are about $65 for a 5000 4S??

Not a big fan of Venom lipos, seen a few puff.

TP's are good, but very expensive and there are better value options around.

Dang, gooood to know Nogas thanks very much.


Ok HobbyKing has offered me 2 x Zippy 5000 45c 5s batteries for 60 bucks each...Should I step on this deal?


Or should I go with the turnigys like you said and stick with the 4s?


They have a Turnigy 5s , but it is a 45c-90c discharge doesn't give an exact ratio and they are 78.

Matter if they are nanotech or regulars?

I'd go 4s over two 2s packs. It's a pain to charge and worry about one of the batts being a different voltage. I ran 5s 5000mah 25c Blue lipo (sold at hobbypartz.com) with a 2000kv motor and they did great. Wicked fast. Too fast for racing.

I run a 4s blue lipo and its been great at 30c. i copy the sentiment about venom. they tend to be kinda junky it seems. i also run the 2s turnigy nanotech lipos and they have been pretty good thus far (great price too!) just pay the little extra for the faster shipping. mine took about 3 weeks to get here...

I guess Im a big worried because I use to run a gas XR Works mugen with a 3hp motor and that thing would FLYYYYYY, couldn't keep the front end down on a turn cause it had so much power.

Suppose I'm just scared because I've never seen an electric 1/8 scale car and am worried it wont be very fast.

Get some Gens Ace 4s 40c. I have a 30c and it pushes harder then my turnigy 40c, like noticeably in the same buggy that u have. Best bang for the buck for a ROAR batt around 70 nothing can touch them. U could also change gearing to 16/44 (15/45 is stock).

I looked up the Gen Ace batteries, none on ebay. They have them at Hobbyparts however they are hardcases, will a hardcase batt fit in a 8ight?

I'm down to the turnigy , blue lipo or the gens ace batteries....Not sure which one to get.

Hardcase should fit fine. The added bonus is they tend to be more durable (resist puncture etc) than soft cases. that said almost all my lipos are softpacks and i havent had any problems yet.

For the power side, trust me.... You will be more than happy. If you do the calculations you are looking at between 1-2 hp depending on voltage and efficiency but an electric has instant torque. remember alot of nitro cars run 2 speed transmissions where BL you just need 1. I have no problems keeping up with the nitro buggys in my hyper 7 electric conversion.
