MAW lightweight battery kit.
 

Did some test fitting for Motive Autowerks last weekend on their new BRZ/FR-S battery.

Battery is 11.7 lbs.
Battery box is around 7 oz.

Uses inserts in the stock lower bracket to hold it down so you'll pass tech.

Looks good, how much does the kit retail for?

Honestly, I'm not sure yet. I'll have to talk to them about pricing, but most likely in the ballpark of your typical lightweight battery trays out there.

What brand is the battery? Specs on it?

It's an Odyssey PC545.

Cool, here are the specs:

545 cranking amps for 5 seconds
495 cranking amps for 10 seconds
420 cranking amps for 20 seconds
Short circuit current over 1200A
18 minute reserve capacity with 25amp load
Female brass terminal w/M6 SS bolt
Length 6 7/8"
Width 3 1/4"
Height 5 1/8"
Weight 11.7 lbs


Odyssey design:
2 year full warranty
Rugged Drycell sealed design
Military grade
Vibration resistant
60% more starting power
Deep discharge reserve power
2 year storage life
8-12 year design life
Can be mounted flat or upright


Retails for $137

Any updates on availability and pricing yet?

Not yet. We asked for some changes to be made.

would you recommend using this battery in the winter time?

funny that you should ask that. We've purposely been leaving ours outside on then going out and starting it every few days to see how it does.

So far it seems to be doing just fine.

comparison to FT86Speedfactory??? that kit is around $250...

Here is the details on the battery:

545 cranking amps for 5 seconds
495 cranking amps for 10 seconds
420 cranking amps for 20 seconds
Short circuit current over 1200A
14Ah
18 minute reserve capacity with 25amp load
CCA - 185

Those CCA pale in comparison to the stock Group 35. Have you considered a box for everybody's favorite, the PC680?

we have, and we discussed it at length with MAW when we asked for this design. Given the emphasis on the weight on this car, even from the manufacturer we opted to go with a lighter battery that we think will still meet the FA20 owner's needs.

Any updates?

Looks nice.

Hmm..Any chance we will see an application for these Shoroi Lithium Batteries.

540CCA, capacity of OE siezed battery, and almost half the weight of the Odyssey PC545.

That is an interesting one. let me get one in, and talk to MAW.

I do know they dropped off a new setup with the changes we wanted. now to find the time to fit it.

I'd like to also mention the Braille GU1R as it is actually labeled for automotive use.

and that is where you need to start looking at the price balance. while you may be ok with $550+ for a battery not a lot of people will. given that I have to buy trays in large batches that will be cash tied up in inventory that just won't sell like the pc545 setup.

The price of this battery seems more reasonable.
Did you guys end up getting this model? Any updates?

I've been running this battery for a week with no issues. It'll fit into just about any small battery box. It comes with a ton of shims you can use.

Did you have to get some different posts for the battery and what did you do for a tie down?

Posted what I did here: http://www.ft86club.com/forums/showthread.php?t=32544

Won't pass tech inspection but it's plenty secure. I'm debating whether to move the battery.

Very cool! The battery looks secure to me not sure why it wouldn't pass inspection or maybe get a custom tray done at a local metal shop like the griffon one. Would you happen to know tge capacity of the stock battery compared to the Shorai?

is it for sale yet as a kit?

not yet. still working out some details on the design. That's what kills us on time on these things. Getting something 90% is usually quick. it's that last 10% that takes FOREVER.

IMO, the Shorai is a great way to go because it's 540CCA and weighs slightly above 5lbs when on the other hand our stock Panasonics are 320CCA or 390CCA according to another thread on the cite and weigh almost 30lbs. The Braille posted earlier above is awesome but costs $577 and the Shorai is in the $300-315 neighborhood and still weighs about 1lb less than the Braille. Just an idea but maybe you guys can offer different battery mount kits for customer preference?

Any news?

really wanna see pics of that shorai! @TRD_07

No news. Likely won't be for a while.

While the delay seems unusually longish, how has the pc545 battery held up so far?
Thanks for update.

I went with a Ballistic EVO2 16cell battery that weighs in at a heavy 3.5 lbs.
Only 500 cranking amps.

Hey, thats the battery I was thinking of going with! How long have you been running it? Any issues?

The only thing holding me back is that lately I've been driving the car just once a week.

I have been running it for about 10 weeks now. No issues so far. We sell them where I work and have only had a handful of defective ones over the almost 2 years we've sold them. A good friend of mine left his in his closet for almost a year then hooked it up in his can and it fired right up.

Wouldn't this be problematic for very cold Canadian winter?? Like, the CCA is really low..

No, it'll actually work just fine. It takes a lot less current to start an engine than most people think.

For those interested in a smaller battery, it's a fine way to save weight without significantly affecting your ability to start the car reliably.

It's worth noting the difference in capacity. 12 Amp-hours (Odyssey PC545) vs 43 Amp-Hours (Panasonic N-60B24L/JE).

Link to Panasonic battery - I'm pretty happy with the choice, from an engineering perspective.

With a Braille or Odyssey mini-battery... You can't sit in the car and listen to the radio for hours or install a monster sound system (drop the bass = drop the voltage). For those applications, I'm a huge fan of Optima and other AGM batteries (like Deka, Diehard Platinum, etc). Yellow Top is 48 Ah with plenty of cranking amps and a sealed design. Start building a bank of Red Tops in parallel if you're drawing more than 2kW or so.

I will never buy an Optima battery again. Their quality has gone to under 1 out of 5 in the last 5 years.

On a related note, I heard that Johnson Controls was doing alot of shuffling within their automotive groups... but I figured that Optima was a cash cow and would not get touched.

I've had 7 of their batteries (1 blue, 2 yellows, and 4 reds) and they've been solid. In Houston, we had an Interstate distribution center down the street... so I'd get lightly used batteries for dirt cheap. Always good customer service, and they were quite open about the hardware differences (note: internals of a blue top look identical to a yellow top in many applications). We always got 3-5 years out of them and they saw some abuse.
