30lb weight saving with LiFePO4 battery - is it worth it?

Are you dailying the car? Thanks.

take a look at group26 batteries - it's basically the same height as group47 with a smaller footprint.
I've had one of these in my car for a year - under 14lbs.
$1k for a battery is insane.

Thanks!

I will never pay $1k for a battery
the antigravity is 14 lbs

the mightymax group 47 is $230 and 9 lbs

I have good experience with the brand. US based with batteries made overseas [EDIT] Vietnam for sealed lead acid, most likely China for LiFePO4 [/EDIT]

I’ll take a look and see if they make group 26 and how much it weighs

[UPDATE] Correction 9.2 lbs for Mighty Max group 47 H5. Mighty Max does not make group 26 as far as I can tell [/UPDATE]

China owns a lot of earths lithium too, so basically all lithium comes from there nowadays

you're paying for the BMS imo

I've run LFP batteries in older street motorcycles for many years without issues. In that application they are better than lead acid (and never leak acid).
I don't run them in my newer electric start only bikes. Newer bikes, like cars, have small electronics drains. These drains are bad for LFP if the vehicles sit a while between use.
Also LFP's tend to fail all at once, where lead-acids generally give warning (slow cranking, etc.).
Before installing a LFP in a CTR, I'd want to see someone on YouTube testing it and cutting it open to see the quality inside.

China produces 21%

Australia produces 32%

US production is "withheld" but US has the most "Identified resources" about 20% of all identified resources
