Hi guys,

I need to buy a battery for a car I'm selling for a buddy: gutted '86 widebody 951 race car. I know you can use really small batteries, but don't want something that someone will have to constantly keep hooked up to a trickle charger, & don't want/need to spend $100 on a 30lb battery:

Walmart/AutoZone suggestions??

Thanks,

Mark

 

I've seen riding mower batteries used... Personally, I've been very happy with my Odyssey - but it's more than $100.

 

I had a wheel chair battery ($40 to $50). For a couple of years. Agree with above I now hae an Odessey (sp?)

 

I tried Shorai and it didn't last one season. Friend had the same experience as me, so I would stay away until they sort them out a bit better. When it worked it was amazing and weighed almost nothing.

 

PM Tony G or maybe he will chime in. He is using what I believe to be a Harley motorcycle battery in his track car.

BAB26-12 or BAB30-12

 

I used the odyssey for a bit. 220 cca isn't much though and barely started my motor if it was cold. (takes a few more cranks than a warm day.) Harsh news on the Shorai. I just bought one.

 

BAB22-12 is the same size and same weight as the Oddysey PC680, but half the price.

If you still have stock radio, amps, afterrun turbo coolant pump, and alarm, get a larger battery.

 

Yeah, I might put my battery in the race car as it's 3 years old already (standard 944 battery) & just go with a new one...or keep mine & put a cheapo in it: it's gotta kill switch so that'll help.

 

I'm going to try another one too, but this time I'm going to use more foam to try to isolate more vibration... don't know if that will make a lick of difference though.

 

There's nothing wrong with the Shorai. They are great.

If you have a problem with it, it's because your output voltage from the alternator is too low. These are Lipo batteries and will die quickly if the voltage drops too low. I think with the Shorai it's 13.5V. That said, you can tweak the alternator out put so that this doesn't occur.

NAPA, Deka ETX18L or smaller if you like.

 

So a 300cca battery works at least: that's good to know.

I have an Odyssey in my Typhoon (rear mounted), and if it's not fully charged, it won't crank the engine over. It's a nice size, but I'll be looking at stronger batteries soon.

 

XsdweI just went over the shorai web site and specs. The battery cannot take a charge using more than 24 amps. Our alternators are way more. I'm pretty sure this is the problem. I might rig the battery up with a clamped charge load of 20 amps with some magic circuitry. I think I will run a 16 volt alternator to solve my fuel delivery needs. (fuel pump flows crazy at 16-18volts) That will also run my ignition, water pump, and fans with that voltage. I will install a step down for all the accessories. That's the game plan for now anyway. Its a work in progress.
