The best thing about a Braille is you can feel it in the dark.

@86TOYO2k17, if you didn’t like @Strife26’s Odyssey PC680 because of weight, you’re definitely not going to like my Odyssey PC925. That said, here are a few photos of how it looks in my car:

Are you having any issues with your odyssey battery? I just picked up an Odyssey battery.

I have a 2lb shorai battery. The lightest of the light.

None - it’s been great and can go two weeks without being on a battery tender and still start the car. It’s not the lightest solution, but it’s significantly lighter than OEM and still very practical for a daily driver in the real world. I’m very happy with the battery and mounting solution.

Which Shorai in particular?

Sapphireho 12-12-2018 02:21 PM

Since this came back up, I'll add my 2 cents.


My only experience with light weight batteries is with my Lotus. I installed a Braille AGM. The car has an alarm. If I don't drive for 4 or 5 days it is dead. Hooking it to the tinder is just part of the daily routine now.

I thought this Shorai: https://www.shoraidirect.com/en/p130...ty-case-type-3
could withstand our not so cold winters with less than 10-20 days per year below zero temps but from what I read here I should review my decision...

It is a very tight fit with the catch can. I have the same setup as you. My only problem was i disconnected the battery sensor on the negative side to make everything fit. I did my own custom battery tray mount.

Found this article about how Li-Iron batteries work on cold climates, they work fine up to 0F/-17C degrees just need different crank process from lead acid batteries at low temperatures:

I decided to go with the largest shorai battery, with my custom tray that secures the battery way more then oem does. it’s 5lbs 15oz. Car is garage kept and winter just started. Havnt used a tender yet. Last week it got down to 26F with ice on ground. Car cranked up better then oem used to and after sitting for 48hours over the weekend. Havnt let it sit more then 2days though. After winters over I’ll have a better personal review of a shorai for year round DD.

Over 1 year on Odyssey PC680, no issue, mostly DD, very mild climate, no issue over a long weekend of no-use but I don't think I've left it for a week or more yet. Will know next spring probably. My commute is usually 15-30 minutes.

Not bad for a ~$120 battery that is two day delivery from Amazon and worth ~10 lbs of weight savings, OE battery is $200+ iirc.

A 10lbs weight savings is within the range of feasible without too many sacrifices.

spitsnaugle 12-13-2018 11:05 AM

I have a Deka ETX20L (same as Braille B2015) Customized the factory battery tray and bent up piece of aluminum for a hold-down.

Battery goes dead if the car isnt driven in a week or so.

Could be something with my engine swap, or my dash cam. Been focused on other things at the moment so I haven't started probing with a multimeter yet.

Lithium (iron phosphate) batteries are by far better in every aspect from lead acid / AGM but they are quite expensive and not for very low ambients (AGM too) so suitable for some climates only as ours in Greece.
As for weight savings at 5-10Lbs for a LiFePO4 battery there is no comparison, I think weight shouldn't be first decision factor when you are at less than 50% of the OEM 30Lbs battery!
