How often to fully cycle EP12 12 batteries?

[mikrt]

Hi,

I have had a pair of EP12 batteries for a month, and am very happy with the install and the performance (batteries only - no solar (charge overnight on IOG & signed up to Axle - events only)).

One thing I'm not sure of however, is, is there a requirement to fully charge & discharge the batteries occasionally?

My max charge is set to 85%, and I can set that to 100%, but I can't see how to set minimum to 0%.

Do I need to cycle, and how to set to 0% if I do please?

Thank you.

In the UK, you can only set a minimum floor of 10%, max 100%.

Wyndstryke has posted a reply in 2nd post down that's fairly comprehensive.

Thanks @MaterialBarracuda48

So I'll forget about the 0% then.

Regarding the 100% weekly charge recommmded, is that what most users are doing? It's a pity the scheduler doesn't have a weekly option to automate this if so.

Thanks again.

I was on IOG, so mine would hit 100% each night... but the trick was for me, was to discharge a little after the off-peak rate finished. I discharged for 1hr from 05:30 to 06:30 on a single EP11, the SoC dropped to 55~60% SoC.

The system also seems to charge the battery in a trickle (maybe a firmware bug) so the SoC would creep up by around 1% for me every 30mins on an average


Will has many excellent videos on youtube to look at https://www.youtube.com/@iameccles/videos

This one in particular should be a good starter

Thanks again

I'll take a look at the YouTube videos over the weekend
