We upgraded to lithium batteries in our Wolf Pup travel trailer. We quadrupled our 12v battery capacity with this simple upgrade.

  • Always remove the negative first. Less chance of a short out. And put negative back on last.
  • @WayneTheSeine
    Not trolling you just a safety tip. Remove the ground wire from the battery first. As you were unbolting the positve first you could easily come incontact not only with the frame but more importantly the propane tank and that would be a major bummer....maybe even fatal if the wrench were to weld itself to the tank. I don't even want to think about that outcome. Nice install. I am about to do the same and I am hoping I can place the battery in the same area as yours.
  • Most LiFePO4 batteries have safety electronics that will prevent the battery from being overcharged, so those can be safely used with any 12 volt system without a compatible charger in your trailer or RV. LiFePO4 batteries can safely charge to a higher voltage than standard lead acid batteries, so your only issue will be a battery that does not charge up 100%. With a same-size replacement of my old lead acid battery, I get about 3 times the battery life with my LiFePO4 battery, event though it doesn't charge to 100%.
  • 👍Awesome, Kurt! I noticed they were on sale and after watching this video I decided to buy this battery!! Thanks a lot✌
  • @knowledge8039
    My bms never work right ,put in simple 10.5 volt disconnect for your main concern.
  • Buying the "Plus" version (200ah BMS) of this battery was a great idea. People who want to upgrade their battery bank to a single, larger amp hour lithium battery need to pay attention to the battery specs, especially if their inverter is over 1200 watts. The battery monitering system (BMS) needs to be able to handle the current your inverter demands. Many of the cheaper 200ah batteries only have a 100ah BMS, which means it WILL NOT allow continuous current draw over 100 amps (1200-1300 watts). Amps x Volts = Watts. A 200ah BMS will allow the battery to handle 2400-2600 watts of continuous inverter draw. For even larger inverters, you're going to need a higher discharge-rated BMS, or a second battery to share it's BMS discharge capabilities.

    Besides just checking spec sheets to see if one's 12 volt converter/power supply is compatible, but if you have to do something to it, to put it in Lithium mode. Mine required making a jumper wire to connect two jumpers on the back. Believe it or not, that was the hardest part of my conversion due to its location. Also, I had to disconnect solar, as the master battery kill switch doesn't remove the solar charging.
  • @michaelagold4580
    How do you know if your present INVERTOR will work with a lithium battery?
  • Thanks for the video, I own two Timeusb 200ah pro batteries for my RV energy storage and they actually produce 230ah, I asked their customer service and they battery actual capacity will be greater than the labeled capacity. Really a great value and have used them for so long They have not had any problems. nice!
  • Just checking in to see if you made videos on the solar upgrade and how to run appliances off battery
  • @StoneRunning23
    Thanks, hreat vidoe.. im looking for the followup video?
  • Thanks for the great video.. did you put out how to install solar, cant seem to find the videos ..thanks
  • Really enjoy your videos, informative and easy to understand. Question on inverters. I have a Xantrex Freedom Pro 2000 inverter with 300w solar panel and 2 100 amp group 27 agm batteries. I believe this inverter handles lithium, but do I have to adjust any of the setting on it?
  • @stv111play
    thanks freind explained nicley. is it worth going lithium without the solar . just the invertor~
  • @krileymac
    How's the next phase of the upgrade going? Very interested in your solar project and I really like how you present your video. Thanks.
  • @billycordery6479
    If my travel trailer has a convertor, do I need to change that?
  • @etepstudios
    What size hole did you drill in the floor? I’m guessing 3/4” based on the link to the loom you provided? I was debating between 3/4 and 1” for 2x6gauge wire. Don’t want a larger hole than is necessary.
