Time to replace 4 nine year old Trojan T105's for my small off grid cabin. Was thinking about going with a EG4 Lifepower24vt, but the more I read about BMS issues and firmware updates, makes my head spin. I want simple. Is it just better for me to go back to lead acid ? What would you recommend?

Definitely not lead acid. LiFePo4 seems to be very maintenance free for the most part.
 
About 3 or so weeks ago I swapped ot my dead/dying lead acid batteries.

Replaced it with16 x 280Ah cells, new bms, new 10Kw SRNE inverter and new wiring.
Took 2 weeks to learn and work the kinks out of the system, slow and steady without haste nor worry.
This site has been a great source of info on setting it up properly and working out some setting in the inverter.

Now my new system has about 40% more usable capacity, weighs almost 1200lbs less, more powerfull inverter and overall the system is much quiter and more reliable then my old setup. Plus, now I can pull out my phone and connect to the BMS to see how my batteries are doing without having to get out of bed, if I so choose...lol.

In the end the whole new setup was almost $300 less then just buying the exact same replacement lead acid battiers I had.
Worth it, now, less stress, longer lifespan of the batteries, more capacity and now I can power everything I need to and then some...
Plus, no more messing around with sulfuric acid and having to top up the water in the old batteries.

In the end it boils down to your budget.
