The stock battery is 56 lbs. The 40ah antigravity battery is 13lbs. 43lbs savings.

Yeah, it's something that a lot of folks have been waiting for. Hopefully, now that they are starting to be offered by more established brands, availability will start to expand... and prices will start to drop.

A caveat... LiFePO4 is very robust and most of these automotive batts come with management circuitry built in. Still, you need to be cognisant of its properties, which are different from a traditional lead-acid.

Imagine what it does for cornering and handling in general.

I haven't looked at those batteries much vs. traditional car batteries.

What are the properties and differences? A link would be fine.

Thanks in advance!

This is a good link that answers the common basics: Frequently Asked Questions That's just one I'm familiar with and have bought several of their batts. Other mfr will also have their own FAQ page. Pay close attention to the sections on charging, storage, and cold weather expectations. Different LiFePO4 mfrs could employ different charge/discharge protection circuits, but fundamentally, the cells are all the same, so it's best not to take the mfr's claims as gospel and better to assume worse case.

LiFePO4 chemistry is related to, but more robust than, the typical LiPo and Li-Ion batt packs that are in consumer electronics. However, they don't take abuse like good old Lead Acid can. Doesn't mean they are fragile or prone to failure, but you should ideally use a battery charger that has settings designed specifically for LiFePO4. Take proper steps before long term storage. Don't just assume you should hook up a trickle charger and leave it on, like a lot of folks do with Lead Acid.

Yes! Thank you for reminding me, those numbers are spot on.

Powertex is having a Labor Day sale 10%. the H6 seems to still be in stock..

 

[djerickd]

they mentioned the H7 will be $150-200 more when its back in stock so went with H6..

EDIT FYI - H6 will require a custom bracket to work...
