Lithium Battery Storage

 Packing up for the off-season? Don’t forget about your LFP battery!

So you’ve got a nice new lithium battery setup in your motorhome, caravan, or RV—awesome! But now that things are cooling down and you’re parking up for a while, there are a couple of small (but important) things to keep in mind to make sure your battery stays in great shape for next season.

Here’s the big one:

 Turn your battery OFF and isolate your charging systems.

Why? Two simple reasons:

1. If something’s going to fail (like your solar controller or wiring), it’ll likely happen when you’re not around to notice.

2. Your battery isn’t really “off” just because you're not using it. The BMS (Battery Management System) inside keeps ticking away and draws power 24/7.

For example, our 12V batteries BMS draws around 70mA just sitting idle. Sounds like nothing, right? But that adds up to 1.7Ah a day (obviously unnoticeable when in use), or 50+Ah in a month. If you’ve stored your battery at 40–60% charge and failed to switch it off, it could be flat in just a few months.

But don’t stress - the solution is simple.

1. Charge the battery

2. Switch it OFF (yes, our batteries come with a built-in switch!)

3. Isolate any chargers or loads (some solar controllers can turn the battery back on)

Then… go enjoy your off-season without worry!

When you’re ready to hit the road again, just switch it back on, give it a top-up, and you’re good to go. Too easy.

We include this advice in our manual—but let’s be honest, who reads those cover to cover?

One last thing: Most manufacturers only quote the cell self-discharge rate (typically <3% per month), which sounds great—but it doesn’t include the constant drain from the BMS. That’s the bit that really matters when storing your battery.

Pro tip:

If you're storing your battery for 3 months or more, try to run it through a full cycle (charge → discharge → charge) around the 3-month mark to keep everything healthy.
