Best / Largest main battery?

[RK Racing]

My same battery just went out at 2 years 3 months. How is yours lasting? Thanks.

Looks like this thread got a jump start

Debatable if it's the best since the technology is relatively new in automotive applications. But it's the biggest LiFePo4 battery in physical size (H7/Group 94R), capacity (80Ah) and cranking amps (2000CA).

Been running it for a little over a month and no issues.

Is our charging system set up to charge Li Po batteries correctly?

That question is above my pay grade. Conventional wisdom around the Internets says NO... the charging system in Glads and JLs are not set up to run LiFePo4.

That being said, It's doing what a conventional cranking battery is supposed to do. Cold start in the morning, voltage hovers around 13v.

Some folks are thinking Energy Storage LiFePo4 and Automotive LiFePo4 are the same thing. That's where the confusion maybe coming from... I THINK...

Do a simple Google "AGM vs Lithium" search and right at the top Google AI states...

"Not Suitable for Starting Batteries: Most lithium batteries are not designed to be used as starting batteries."

No. Some appear to have their own electronics built in but the jeep system voltages, temperature compensation and so on, are aimed at agm.

You still running the AUX battery?

No

Can't run a lithium crank battery and the smaller AGM in the same vehicle.
If he was to run the aux battery, he'd also have to swap that out or there would be serious issues.

Correct

AntiGravity explicitly states not to run in series or parallel.

I was getting there with my question. I’m glad to hear it

Not even with their own?
That contradicts what's going on in the world where lithium are in huge banks of batteries.
I can't see any reason they'd not run in parallel with a LIKE battery.
It would take them completely out of any dual-battery setup. And it would mean you can't even jump start them.

Remember, Energy Storage is different from Cranking.


Automotive LiFePo4 crank batteries carry a battery management system that will disconnect when it reaches a low voltage threshold. The BMS will reserve enough cranking amps to start the car. So you never need to Jump Start these batteries.

But what about in Iowa, at twenty (20) below? (or Canada, at 30 to 40 below)

I know - storage is different from cranking - and that's why I brought it up as a head-scratcher as if it was simply a lithium battery - there's no reason for no parallel connections - you explained it with the "BMS".

So it's not the battery, it's the electronics, that cause it to not be compatible with interconnecting with other lithium batteries.

Again above my pay grade but yes, just taking Antigravity's word about not running parallel.
