Using Lithium Batteries

[Crazy Brit]

I have always said that this idea of only charging your Lithium Batteries to 80% and then only Discharging to 20% is a load of Balony. It is often stated as the way to best look after your Lithium (LiFePO4) Batteries, but really is a nonsense.

Just came across this Video posted yesterday by Will Prowse, who a lot of people regard as THE god of Lithium and Solar and it is good to see he is dispelling this myth. Maybe more people will believe him and use the blooming batteries they bought properly and fully!

I am starting the Video at the point he discusses about charging and discharging levels .... Also watch all to the end!

Remember - Use that Battery!

This is why I built my own battery. So I could use it as I wanted and if I screwed up I only had myself to blame. I watched a fair bit of Will and the off grid garage particularly for the bms settings. It's not immediately obvious what some do. Having access to all the settings is a real bonus.

I visited a renewable exhibition at the NEC and spoke to one of the techs and he was a bit surprised I was only using 306Ah from my EVE MB30 cells and not the >330 Ah they are capable of. I didn't tell him I got 339Ah out of each cell when I tested them before assembly into the battery! Lol

I dip and and out of Will. He has some great info for sure but don't really care about seeing 20 battery tear down videos a month.
I find Andy Off-grid Garage too hard going. Even when I see a video released that covers a specific topic of interest, his presentation style twists my melons too much to be able to watch for long.
