Race battery's

[jay182bg]

I need a new battery on my 182 track car was looking at race battery's? Car only gets used ocasionaly on track od day on road. I know they like to be kept in use or go flat easy. I have a solar trickle charger which can leave plugged in. What would people go for and are they easy to mount if wanted in same place cheers

If you're buying one, it would make sense to relocate it at the same time mate. I put mine behind the passenger seat. Then put a cut off switch in the Live wire too.

I've got a Varley Red top 25. Works a treat. Car doesn't get much use. But then when I know it'll be weeks before I start it next I do try and put it on trickle charge.

Ok mate thanks relocating easy to do?

Oddesy 25 for me

I use a Powervamp (can't remember model number) battery, relocated behind the passenger seat with a cut-off switch. I've had the cut-off switch switched off for at least a month before and the car started up fine without needing to charge the battery.

I've got the same to mount, did you use the odyssey terminals to connect to standard wiring? and what cage did you use? i'm keeping o/e location too for ease of fitment tbh

I made a plate for the bottom to match the shape where the old battery goes out off 3mm aluminium from eBay, and I bought a cage to fit the battery from a company online ill see if I can find what company later, then I pop riveted the cage to the plate, all in cost bout 40 notes for that set up but looks stock so I'm happy with that

I used fittings I bought from demon tweeks, think they had a m6 thread bolt and then they just screwed into that, have a look on there web site they only do the one kind and that's the ones I had

 

[Clio Nabz]

I kept the stock location too as was easy to sort rather than moving cables everywhere

I'm going for our Motorsport mount kit tho ?

Like that set up @Clio Nabz Exactly what I've been pondering. Is it stable, doesn't move much?

Pure Motorsport I mean how much cable do I need to relocate to behind passenger seat ?

3M will be enough to do both the positive feed, and an earth lead (if you're going behind the passenger seat - I got 5M to relocate mine to the boot). Just depends on how you want to route it.

I used a longacre thru adapter for the bulkhead: https://www.merlinmotorsport.co.uk/p/longacre-battery-cable-through-panel-adaptor-45700

3m of red and 3 m of black? Sorry new to this

It's solid pal, I used 3mm alloy for the base so it's still lighter than steel but still strong enough to keep its shape

 

[bozothenutter]

what guage of cable to use for relocation to the boot?
how many amps does a 1*2 pull?

 

[David172]

Bit of a thread revival but didn't think its new thread worthy, hopefully people will see this!

I'm looking at the Odyssey 25 - PC680/redtop 25 battery but I'd like to go as small and light as possible so could I get away with the Odyssey 20/PC545?

Will it have enough cold cranking amps? Plan on keeping it in the bay if this makes a difference (colder etc)? No aircon or radio to power.

Thanks

Powerlite would be worth a look - https://www.powerlite-units.com/lithium-ion-batteries.html

Got a PS30 in my Punto. Bought from the Green Spark Plug Company, asked them which they'd recommend for my usage and they went back to Powerlite with the enquiry.
Fitted spring time last year, occasional road and track use and was sat in the garage on charge when parked up, car has radio/alarm. Think I left it off charge for a week to test it, had no issues.
Dropped nearly 10kg after I'd modified the battery bracket to accept it, managed to fit a catch tank in the space it saved as well.

Tempted to say I could of got away with the PS20.

I accidentally left it off charge for two weeks at the start of this year, not sure if that has killed it or not yet. Put it back on charge and the car started after a couple of hours. Just going to cross my fingers til I bother to use it again and see how long it lasts off charge!

You can run the PS-09 easily on a track car.

 

[David172]

That would be amazing becuase it's more in my budget and its tiny! The CCA looks good too. Hmmm

 

[scullyg40]

I have the PS09, and it's been without issues. I do disconnect the battery after each trackday though.

Ah thats promising then. I drive it once a week and about 6 track days a year (hopefully) so isnt used much. I want to keep it in the engine bay so ill have to sort out a way of disconnecting it after ive locked the car. Maybe just leave the bonnet unlocked (ill have aero catches soon anyway). Might cause alarm problems though. I'll make it work!

 

[R3k1355]

A battery isolator switch or circuit breaker will do the trick.

No point in moving a battery that weighs less than a kg.

Yeah but wiring...lol. The witchcraft that is electricity baffles and scares me. Maybe ill pay a professional to fit a cutoff.

 

[David172]

How would you keep central locking with an isolator switch? It would need to be on to lock the car from the outside?

I'm using this mobility scooter battery in my type r engined mr2. Cranks the engine over ridiculously fast, is nice and cheap but I can't confirm what it's like over time as I haven't run the car on the road yet.

 

[Kev@KAM]

you'd hope its decent otherwise lots of old people will be getting stranded in random locations...

Got this in my ebay basket, i'll get it ordered now I know it works in a MR2

In doing so you'd probably add a KG or two of battery cable anyway.

YUASA make some good batteries so longevity should be acceptable,I have used both myself and the odyssey is superior I'm still on the same odyssey battery now for the last 5 years, the trick is to charge them when required with a proper AGM charger or trickle charge them and they will last.SJ.

 

[JB21]

My car came with a Varley redtop 20 which was near new. Dummy here kept letting it go flat and eventually it blew a cell and took my ECU with it. So either keep them on trickle charge when not in use or disconnect them.

 

[Mertin]

I dont think li ion batteries like a long cable run on them and seem to be best off in engine bay
