Battery renewal

Depends on your objectives.
I use standard AGMs in the OKA for both the house and for cranking. They do the job well and have done so for many years. I would never get my money back if I changed to lithium. They are still simply too expensive.
I am building another OKA off road motorhome now. It will get lithium for the both crank and the house to save weight.
Cheers,
Peter

I bought my last ones from here, in mid 2019. I am using a 120Ah NPP for cranking the OKA.

Price is no indication of quality, in my experience.

I followed Pete lead and 18 months down the track not disappointed.

If you have the money Fullriver will not disappoint as long as your back up solar charging system is up to the mark.

Renco batteries, a little cheaper are also with my experience value for money. 8 years life span for us.

I thought I may replace the caravan with a new one, so I selected the cheaper option on Pete's suggestion and very pleased, still working well resting at 12,8 volts after a hard 18 months service.

Battery value by 2.

Remember that changing from AGM to lithium requires new charging equipment, if have solar need to change solar controllers

Not necessarily.

Many good charge controllers have user controlled charge parameters. Even my 17 year old Plasmatronics solar controller has, so it can charge ANY battery type EXACTLY as the manufacturer specifies.

I have four 26AH gel batteries in the car due to space issues. It would be useful to change to lithium to save weight, but I still have the same issues finding corners in the car.

If weight is not critical stick with lead acid. Don't forget that with 4 x 100AH you have 4.8kWh to use if needed.

If you have to use 100% of the battery capacity once a month due to inclement weather it is only 60 cycles over 5 years.

Often people put in less AH with lithium due to price. But at the end of the day it is the AH you need to run the fridge or other items in inclement weather.

I have four batteries, connected as 24 v, two for truck two for house. What would you renew with. AGM or lithium, I think they are about 100 amp hrs each. Recommendations appreciated.

Blue River brand have a very good reputation for AGM batteries.

Many varying views on Lithium. I bought one from a WA supplier which appears to me to be fine. I dont know of it is rebranded but for what I use it for I cant see the problem.

Do some research on your present charging system being suitable. It probably will need modifying if going Lithuim.
