Hey all I'm looking for some help on choose a battery for my race car. I'm building an all motor drag car that's used for racing only. The car will currently be setup for a 12 volt system with an alternator. The motor is around 14.5:1 compression. The battery that I'm looking at using is the Braille B14115. That battery has 904 PCA and 15 Ah. I'm wondering if this battery has enough power for what I need?

 

why run an alternator for drag racing? I can understand needing one in circle track etc, but you are running such a short duration, just charge the battery between heats

 

Pm me for a better battery than the Braille for much cheaper

 

its no secret dude. big crank.aka honda gold wing battery.

 

lithium batteries are the next big thing

 

I wasn't trying to be secretive man. I have a line on a manufacturer that is wanting to tap into the drag racing world. I'm not a sponsor, so I did not want to violate any rules.

We have a distributorship signed up with them and will be doing a group buy within the next 3 months.

 

I just bought a Shuriken SK-BT20. From the reviews I have seen, a lot of honda-tech'ers have pretty good luck with them. Much cheaper than the Braille batteries as well.

Here's a link to the one I bought:

16v and be done with it

 

I am a fan of 16v but a lot goes into running them at the track (Gotta have power to charge, time to charge, etc) so not necessarily for everyone

We have been doing some testing on the Antigravity Batteries and we have found the 12v one to be working awesome, we are still working out some charging bugs on the 16v stuff but are hopeful on those too

Very nice lightweight, compact batteries

 

why are you even running an alternator on the track for a car running under 15 seconds? thats a lot of extra drag and weight

 

At this point 16 volt is not an option. From the research I have done it looks like the popular 16 volt battery that is being used is the Turbo Start. Turbo Start looks to make two versions, a light weight battery that weights 32 pounds and a regular version that weights 42 pounds. The battery I look to run is 11.5 pounds and the alternator, belt and mounting hardware weigh 10 pounds with a total weight of 21.5 pounds. The 12 volt system is 10.5 pounds lighter and aprox. $370 cheaper then the light weight 16 volt system. As far a drag turning the alternator, IMO I dont believe will cause that much of a power loss to were the car wont be competitive.

Until Lithium technology comes down to a reasonable range, 16 volt wont be thought about. I can take $1000 - $1400 and put it somewhere more beneficial.

 

you know you can add a switch to turn off field, some Honda alternators require you to cut off two of the wires or it will backfeed and keep operating , just do that and flip a switch right before the run, all of your drag is caused by the field operating while it's generating current, turning it off removes almost all the drag

 

what we are using now

We have tortured our ballistic batteries and still going strong. Very good battery. NASCAR has been testing/using them too

 

Ballistic works great with an alternator and without. Just takes too damn long to charge if running with an alternator
