Default 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!

Thanks!
information on your motor and speed controller would be help full but ill assuming its a full size 1/8 motor and speed 1900kva+ and your not trying to super light it with a 550 cam on 2s. you'll be looking for 4s +4000mah id good probably go in the 5000-6000mah range as the thats a good size before the cost jumps alot.


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.

I would go with the gens ace high voltage 15.2v 7500mah battery with the inboard 5mm bullets.

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..

6000-6500mah.

Love my Pro-Match Racing 6500. Plenty of battery to finish a 10min main and then some. I run XT90 connectors.

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.

I was not there for that race thought it was going to be a rain out but I saw the aftermath on the big Dave's st, and someone handed me a 30lb e-buggy. After the last run... I felt sorry for you guys surprised there was still sand left in the track. Haha

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.

Several years ago, I ran my tekno MBX6 with a Tekin Gen1 1700kv in 15 minute mains on 4500mah packs almost weekly on a medium-large track. I would intentionally lay back from minute 5-12 to try and save power for the last few minutes in case I needed to push. I was probably on the limit of safety margin, but I never once tripped the LVC on my esc or damaged my batteries (I still have one of them).

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.
