Sunflower mine05Tacorunner, what trail is that ?
Had to do it, downsized from heavy XD wheels and 33" MT to these 2021 Tacoma TRD wheels and tires. Took the 80 to Horseshoe dam and had a hard time climbing that sandy road back out, that was the last straw.
Now she it back in the intended rpm range, got her power back and runs SO much better. The 3FE is as tuned as it can be, had to look elsewhere.
They are tucked in a bit but I am not a fan or spacer so it will stay as is. The tires are Goodyear Wrangler Kevlar so no need to change those for now, may eventually go to 285 but for now this is a good setup.

You have any reference info for building our own batteries like this? Very cool setup.I added a 100ah lithium battery to my system. I've had a Batteries Plus X2 Group 31 AGM for several years and running all of my aux power needs off of that. With a 100ah AGM, you really only have about 50ah of useable power without killing the battery. It's served me pretty well, and never ran it too low to not crank the truck. I've had 100w solar panel mounted to my RTT for a good portion of that time, and it has always kept the battery topped off, even when parked for multiple days with the fridge running. However, I still had some anxiety and wanted to increase my capacity. I considered just getting another AGM since an off the shelf 100ah lithium can cost anywhere between $600 and $1000. At best any cheaper AGM would cost around $200 and might only give me another 25ah.
So I considered building a diy 100ah lithium battery. I purchased four raw 100ah cells and a battery management system (BMS) for about $300 (could've been $200, but I splurged on a BMS with bluetooth and a low temp cutoff. I assembled the cells in series and mounted the battery and bms in a Harbor Freight plastic ammo can. The whole thing weighs probably 15lbs, which is a considerable savings over another Group 31 lead acid battery. I added a 120a breaker on the inside and a Anderson plug to connect it my truck's electrical system. The starting battery and lithium house battery are connected to the same power posts in my electrical panel in the cargo area. I can flip the breaker switch on my starting battery and connect the lithium, or I can pull the lithium out of the truck and reset the breaker on the starting battery. My solar and shore power chargers will charge whichever one is connected.
We'll see how it works long term.
Here's a pic of the cells as they arrived

No kidding!! This is perfect, thanks. I have some plans to do an off grid cabin on some property up north... this is quality stuff.Will Prowse on YouTube is a really good resource. He also runs a forum DIY Solar Power Forum - https://diysolarforum.com/
If you decide to go this route, I'd be happy to offer any assistance. I bought the load tester and a bench power supply as well.
It's pretty easy to go down the rabbit hole. I did this in anticipation of doing a bigger project in the future.
That would be awesome. A 24 or 48v system is just as easy and would be great for a cabin.No kidding!! This is perfect, thanks. I have some plans to do an off grid cabin on some property up north... this is quality stuff.
Where’s this?We spent the long weekend on the Mexican “Gold Coast”. Love it down there.
