  I have 4x 5.1kw LFP batteries. I have been charging them with solar to 100% every day and discharging down to normally between 30-50% overnight. The BMS tells me that the SOH (state of health) is 99% after a full years use. Couldn&apos;t be happier.<br>Edit: May 2026 2.5 years @96%

  I&apos;ve seen all kinds of opinions about charging to 100% or discharging to 0%. I trust you the most, so thanks for this video.

  I installed my solar system four years ago on my Cargo camper with Will&apos;s help. I have been in 107° down to 10° with no problem. Ran it to zero several times. Still going strong! Will is the MAN!

  This has been a topic that I&apos;ve been unsure about while setting up my solar system. Thanks for the explanation.
