@erik hi brauchst Du zufällig #strom ? habe sehr gut funktionierende #solar #offgrid systeme (aktuell 2kWh #dchouse #lifepo4 gut und günstig) und man könnte sogar noch 48V wind an die
#batterie anschliessen :D dann kann die #apokalypse kommen?

@bencc

coolgear has some decent USB chargers that support a wide voltage range... I have used some of them directly off solar panels, although it is not officially supported!

I have mostly used electrodacus.com battery management & charge controller for simple DIY installs.

I Prefer #LifePO4 batteries for the safety and stability.

50Wh is about 5 hours at 5V 2A, what you get with those little pocket sized batteries... is that really the scale you're looking for?

Is it possible to convert this rechargeable battery powered lamp from SLA Sealed Lead Acid to rechargeable LiFiPO4? If it is possible, I assume I’d have to replace the wall wort charger, correct?

Rettungsaktion: Wenn die Akkus ungeduldig werden... 🔋

Nachdem die BatteriLifepo4 #Akkupflegeüber zwei Monaten rumstehen, wurde der Ladezustand jetzt langsam kritisch – und sie gingen prompt in den Alarmmodus. 🙈

Da es noch ein paar Tage dauert, bis die Kabel für den Strom vom Dach fertig verlegt sind, gibt es erst mal die Not-Ladung aus der Steckdose. Ich möchte ja nicht riskieren, dass die guten Stücke gleich tiefenentladen und beschädigt werden. 🔌⚡

Testing LFP Battery Failure Modes With Overcharging

As great as batteries are, it’s essential to understand their risks and how to keep them from going spicy. Recently there has been a bit of a fuss about the dangers of LiFePO4 (LFP) batteries…

@lennart It's #Victron's freely distributed Linux-based OS for energy management. It connects via Wifi to The Cloud and I can monitor stuff from home. It is connected to my MPPT solar charger, a Smartshunt and the BMS of my #lifepo4 battery. You can buy a device called Cerbo GX or an inverter with a Cerbo built inside, or download VenusOS and install it yourself on a raspberry. There's an app you can use in an Android device.

Had some troubleshooting with the #raspberrypi running #VenusOS. Turns out a flash symbol on the screen indicates inadequate power. The 12 V dc-dc stepdown is rated at 3000 mA and it looks like we're under 1 A. Changed the USB-A to micro-USB lead after a long session of elimination. That seems to have fixed it and it now boots reliably without bootlooping. Since the raspberry pi is built into the #LiFePO4 battery it was a pig to debug. Have to rebuild it to have the raspberry external.

Ikea's cutlery box fits, if you sand off the edge.

Light installed in the pilot berth. Have been planning this for literal decades.

Pleasantly surprised at how good the old oxidated mast turned out with Hempel's mast oil
