good. i also bought the charger for it.

you need a special charger for these batteries.

 

You really don't need the circuit as long as you follow some guidelines. I had one in my Evo when I had it a few years ago. I built it myself with no protection circuit either, 4.2lbs with mount .

 

Evodan, have you used it as a dd in below freezing conditions? On my bikes they get slow to start near freezing, but I haven't used them below freezing. Kinda cool to have a slow start and then have it get faster as the battery warms up. Kinda opposite of what we're used to.

 

I have to do the same thing during freezing conditions with my R6 that has a 4 cell. I just let it sit in the on position for a few minutes to warm up the battery before starting.

 

Under 40F seems to be the rough cutoff for performance drop. I have used mine in the Evo in 10F weather and it was definitely slow to start yet always did!

 

Do you have pictures of it installed?

How do you make the terminals connect? did you have to put in new battery cables? I dont think the oEM ones would fit.

 

by seeing evodan2004s experience, Im assuming these are the better alternative to the other mini batteries out there in terms of performance and weight savings, ~10lbs up high in the engine compartment! for not too much more $$ ,Im getting one!

 

You can buy normal lead terminal posts from most auto part stores. That's what I did for mine. Then it's a direct drop in cable wise.

Here's my old thread if anyone is interested. Clicky

 

i custom made my own terminals and totally re built my hole harness. no the stock terminals will not work.

sorry buddy but the car does not see the winter months and the garage is heated. BUT the quad see's the winter all the time. granted its a quad i have no issues or slow cranking problems. the car when i let it sit outside over night ''if im working in the garage'' fires right up when i want to pull it back in.

 

Looking into lithium batteries also. Figured I would post up all the links I found here for more info.

Some user info.experience on the Shorai packs.

http://www.baautox.com/forum/index.p...9&start=0&rid=

Just recently provide several Evo drivers with these packs. I hope and will ask them to post their experience on the same thread to the link above.

For reference, the Shorai packs have a max charge rate, it is listed on the spec sheet.

Keep that in mind when selecting a pack for the application.

Shorai warranty is based on:
The required amps to start a vehicle should be 1/3 or less of the battery pack CCA. Warranty may be voided if this is overlooked. Shorai will ask for the vehicle pack was installed and what the starting amps are for that vehicle.

I am working on building a database of these values for reference. This can be easily measured with a clamp meter.

The LFX24, LFX27 and LFX36 packs were originally built for large motorcycles, the long distance travel cruise styles. Working with Shorai to allow their packs in Automobiles brought the warranty terms above.

The smaller battery packs are geared for motorcycles and while installing them in a vehicle may work, as even an 7lb SLA batteries do as well, it just means the battery is being pushed harder and this will reduce its life.

I personally prefer to have something reliable and not have to cross my fingers and hope it starts, this is more so when the vehicle is used in competition, no need to an added variable of a battery that needs to be jump start because it is too weak for the application.

I personally use the 540CCA pack in my SMF Integra with no problems. The car can sit for 4 days before the battery gets too low and will have problems starting the car, the results are the same when using a Odyssey PC680 or the alternate SLA low cost options (265 CCA pack).

When the same batteries (PC680, Shorai 540CCA or SLA alternative) are installed in my STS CRX, the car can sit for 2 weeks and it will still start with no hesitation.

Every vehicle is different and this is based on what is still drawing a current when it is off. Alarm, ECUs, sensor, etc all work differently for different manufacturers.

SLA or LiFePO4 battery packs will all begin to fail if they are discharged below the recommended voltage by the manufacturer (in most cases the cells are damaged and will not hold charge as well).
Lead Acid batteries are more resistant to this but I have noticed in the past, when I left the headlights on my CRX, that a lead acid battery will begin to fail as well when drained completely. Just personal experience, no scientific data to prove it.

Hope this helps.

Thanks

 

The link doesn't work.

 

Bang for the buck, it's still hard to beat a Dekka EXT14 for $65 shipped, and at 11lbs. For the extra 5lbs, I could cut back on the Double Double's.

 

Fixed link for those interested.
