Battery mAh for E-buggy
Hello, I wanted to know what batteries are recommended for e-buggy. I just got a Losi 8ight 4.0 and I need to buy a battery or two. I will be racing.
Also, what type of plugs are recommended for e-buggy. Coming from 1/10 everyone uses 4mm or 5mm plugs.
Thanks!

Dont go with 4mm bullet or plugs. they don't stand the test of time well and were out fast possibly destroying you battery. Any of the center spring connector are straight dead shots to batteries also. 5mm are much much better. Or a connector like Dean's, ec5, xt60 a 5mm or 6mm hxt connector. i prefer deans and 5mm bullets they're the easy its to solder. that Said the battery supplier will probably affect which connector more then you'll get to choose. as a example smc's 4s batterys are all t(deans) type connector, while hobby kings batteries are all bullets(the hard case ones).
im getting smc 5400mah 4s for my setup. but i might get 7200mah i think i can stomach. 81$ over 64 per battery. was going to go Turnigy Graphene but did not like there offerings in these department.

You can order smc with any type of plug fyi. I use xt60's.

Great, thanks everyone. I was wondering if I really needed the 8000+ mah battery to make time.
Net time I’ll include esc and motor, which is a hobbywing xr8+ and my motor is a Maclan 2100kv

Depending on the size of your track, the grip level, and the length of your races you might want to look at the 4500 from SMC. I had the 5400 and switched to the 4500 and love it, they are lighter and shorter in height Our track is pretty big and surprisingly grippy for a natural dirt track and I use a Hobbywing 2600 in my EB48.4 and I make 5 minute races no problem. The only time I came close to a problem was the last race of the year last year and that was because we basically ran a giant oval since the infield couldn't be drained enough in time..

Check with your local track and see how long the mains are and fro from there. My track only runs a 6 no I've main while other tracks run a 10 minute main.

Yeah good advice seeing how long the mains are. All comes down to watt hours and using the smallest pack you can get away with. With the right gearing you could in theory get 12 minutes out of a 4s 4500 mah. If you only run 6 or 7 minute mains hell go with a 4000 mah and gear up lol.

Don't be sorry, that was probably the most fun I had all year!! It's only a little dirt, it cleans off lol. Don't recognize the screenname, who are you? Sorry for the hijack.

Thanks for all the input. The mains are 8 minutes and I would be racing on med size track, not a ton of straight aways. This also get me thinking, does anyone run motor fans, I've seen them but are they really necessary?

Motor fans in 1/8 scale are pretty rare. Unless you are on a huge high traction tracks and its really hot out, they stay cool enough without a fan. For 8 minutes on an average track with decently aggressive driving, you'll use 3,000 to 4,000, mAh. I've seen people run 10 minute mains with 4500 mAh shorty packs, but they are driving as smooth as they can to make the full 10 minutes.

It's good advice to carry a little more battery than is needed. Get yourself into a hard battle and you could find yourself using power faster than expected.
