Lithium battery SoC storage...

At what SoC (State of Charge) should you store your Lithium batteries?

Hi Mike,

Regarding lithium batteries, my understanding is that they should NOT be stored at 100% charge, as doing so can damage them. The recommendations I've seen from manufacturers is that they should be discharged to ~50% before storage and preferably be kept between 20% and 50% SOC. Have you heard something different? - Brian N.

Hey Brian,

Every manufacturer I’ve talked to directly has recommended storing Lithium batteries at 100% SoC. But I have heard of the few manufacturers that recommend storage at 50% SoC.

Since there are dozens of Lithium Battery manufacturers out there, I’ll pull together a list of manufacturer SoC storage recommendations. But I need your help…

What brand Lithium batteries do you have in your RV?

Please leave your Lithium battery brands in the comments below, and I’ll contact each of them to create a master chart on recommended SoC storage. If you’ll help create the list I can create a SoC storage chart in a few weeks.

Let’s play safe out there… Mike
