  1. Need a battery recommendation.

    This is interesting reading. But its AI so take with a grain of salt. Just more incentive to actually run a test. I don't think I would trust the battery MFRs to run and report an unbiased test. But if someone could convince Will Prowse or some other independent to run it, that would be...
  2. Need a battery recommendation.

    Id love to see a test too. I bet you would be surprised as long as the test is with a lithium STARTER battery. The BMS in them is certainly different than the more common lithium batteries rated at 100A continuous or 200-300A short term. I quoted the mfr CCA and peak amps for a typical lead acid...
  3. Need a battery recommendation.

    Come on guys! If you are going to make statements in here, please base them on facts. Here is a quick comparison of an AGM in OEM Bronco sizing to both a diesel truck starting lithium and a lithium marketed for auto use. Which one do you think will run a winch faster/longer? Which will be the...
  4. Need a battery recommendation.

    Sorry not true (italics). Lithium outperforms both in recharge current capacity, and charge efficiency. Yes the alternator (actually regulator) voltage is probably not ideal for Lithium. I dont know if the Forscan options include a Lithium or custom profiles. Cost savings benefit depends on...
  5. Need a battery recommendation.

    There has been discussion on this here before. Someone needs to be first adapter and report on success or failure of specific Lithium starting batteries. EDIT: They guy who said his swelled twice did not say what brand or PN so no help. (I reread and caught that the brand was Antigravity that...
  6. Flat Towing must pull fuses

    I don't quite understand where you measured the 7 and 3, and when. I suppose that's possible, but only if the 12V wiring from tow vehicle to toad is too small or has a lot of resistance for some reason. With adequate wiring (and protection of course), the tow vehicle should provide for all load...
  7. Flat Towing must pull fuses

    Pulling fuses and waiting on sleep is BS. We tow our 24 every time we go motor homing. I thought I might be in the market for another Bronco in a few years. Hope they fix this in 27 models. If not, it would be a no-go for me.
  8. Flat Towing must pull fuses

    If you run a properly fused/breakered +12v charge line from the towing vehicle, that's adding more battery - the battery in the towing vehicle. And it's running and charging most of the time. Why make life complicated?
  9. Purchased new Bronco, found possible solar wiring!!! Need help

    The Orion TR Smart box is for charging the Lithium battery from the Bronco alternator when driving, since the Lithium needs a specific charge profile different from the lead acid charge control built into the Bronco. The MPPT 75 | 15 is the solar charge controller. The little round display...
  10. How far did you travel to pick up your Bronco ?

    380 miles one way. Wife drove it back home from dealership.
  11. $8/mo for connected Nav is too much.

    Mine is also expiring soon. I've used it several times during the trial period but find myself using Apple or Google Maps way more often. The user interface and display/instruction for Ford maps is just different enough to be frustrating to learn. So just not worth it to me. Also, it's an...
  12. New Bronco Owner Antenna questions

    Be sure to unscrew the OEM one and see what sex it is. Either Amazon was wrong on fitment or Ford actually changed the sex at some point. I ordered a male one and it was wrong. (It did fit my F150 so I put it there). So I ended up with this one. The shorter they are the worse reception. This 7"...
  13. Flat Towing must pull fuses

    I wouldn't want to pull fuses either. The 2024 manual has not been updated to require it though. I will keep doing what Im doing. Over 5K miles towed so far with no problems. I still suspect the problem was due to not adding a 12V charge line and the braking system running down the Bronco...
  14. Flat towing with overnight stops - how do you handle this?

    I leave it in flat tow hooked up overnight frequently. And I usually leave the aux braking system turned on overnight as well. (I installed a power pushbutton on the dash for it) I do check (if I think of it) in the morning before moving and sometimes at a stop. Open the door and the "flat tow"...
  15. Leaving in flat tow overnight

    Yep I would suspect your aux brake system has signficant load even when not being used. Maybe break in the power wire and measure it with an amp meter? Or measure at the battery and then verify it is parasitic from the braking system by turning it off or disconnecting. (Note there are normal...
  16. Best antenna for increased reception?

    This is the educated answer. No shorter antennas or boosters will work better than this (with the vehicle metal as a ground plane), for FM. If you are actually listening to AM, all practical antennas are "short". Thats why back in the day, cars had telescoping antennas that would extend...
  17. Is it reasonable to ask for and get 5% off MSRP on a '26 Big Bend on the dealer lot?

    I shopped on price and options, considering up to 500 miles away. I called a few closer dealers after looking at thier online inventory and none were marking down 24's near me, even in early 25. The dealer 2 miles from my house tried to scam me by starting with the wrong sticker price and adding...
  18. Anyone Replace Stock Battery with a Single Underhood Lithium Battery?

    Congratulations deriving all that from field observations! Has your system ever shut down non essential functions due to false low SOC? That would be a reason I would not go lithium for the Bronco. I havent looked if the Bronco alternator has a remote sense line coming out. If it does, one...
  19. Anyone Replace Stock Battery with a Single Underhood Lithium Battery?

    Here are some more options. I will not be the 1st adapter but welcome input from others on fit and performance: Ionic auto battery $439 This one may be overkill but probably better if running winch or other power hog. I have one in my motorhome as a diesel start battery: Diesel truck battery...
