My 2018 Outlander PHEV's OEM 12V battery had some corrosion so I replaced it with this LIFePo4 battery $280 shipped from China's Aliexpress. Hopefully it will last 10 years. you would need the Negative L battery. Their life cycle should last 5 to 6 times those of lead acid batteries. Ebay has some other brand at more than $400 -$600. LiFePo4 battery is much safer than the Lithium Ion battery. The future of EV battery will be Sodium Ion Battery. Tesla said that an upcoming compact passenger car with a potential sale of 42 million thanks to its 53-kWh lithium iron phosphate (LFP) battery pack.

Very interesting!
What about charging, have you installed special charging unit or battery has built-in one?

Daem0n:

I am glad you ask, this battery has a built-in BMS chip inside to regulate charging and you just install it like your regular lead acid battery. You do need a special LIFePo4 battery charger if needed. I always charge my 12V batteries at least once a year at home. I got this charger for both lead & LiFePo4 batteries. I installed it since early January 2023, no problem so far. My detector shows over 13-14V at full charge.

It read 14.6V when fully charged!

 

So the battery is about 1 year old...no problem at all.
