  100 AH

  I originally went with 100Ah lithium. I am in process of doubling that amount with a self made power box. My box will include a Victron MPPT 100/30 solar controller and 400 watt inverter. The box can operate as a pass through to the T@G or each component can operate independently.

  Unfortunately my project ran across a set back when the battery would not charge. In process of replacement. The 100Ah will run my Norcold refrigerator for about 4 days without solar assist.

  100 AH

  I also went with a 100Ah lithium cell to replace the 100Ah lead-acid lump without having to also replace the Victron box and/or upgrade to a more-bigger-more-expensiver power center (the lithium-enabled 30-amp WFCO was hard enough to justify). I'm considering the future long-term possibility of adding another 100Ah cell in parallel with the first one, but I want to finish tweaking the original system first, to determine if I really do need that much capacity.

  100 AH

  I started with 100ah, worked great for weekend trips, anything to much linger and you'd need solar or shore power. Fit nicely in the front, didn't change the weight much, was a pretty simple upgrade.

  Then it broke and I had to send it back for warranty repair. When they shipped me a replacement back I got 2 100ah batteries, and then the next day I received 2 more.

  My wife said "let's install all of them!" Which counted as permission as far as I was concerned.

  It was a bit more of a project than just swapping out the lead acid battery... But I now have an absolutely excessive 5kwh of batteries in the t@g, 4x100ah batteries.

  Shore power is optional for us now**, if we are staying somewhere more than a week we'll put up the solar suitcases.

  
  

  **the stock charger that won't charge the lithium batteries up all the way anyhow.
