    What's the official opinion from the experts when it comes to daily charging LiFePO4 to 100%?

    I feel like this is a topic that's been beaten to death for years but I'm not finding much about it anywhere. Does battleborn recommend charging their batteries to 100% daily? Is a full 100% discharge cycle the same as discharging from 80% to 30% twice? Should I set my solar generator to...

    Best way to charge a solar generator from a 12V LiFePO4 battery?

    The LiFePO4 battery is a Lion Energy UT1300. The solar generators are the Ecoflow Delta, R600 and Bluetti AC200.

    Best way to charge a solar generator from a 12V LiFePO4 battery?

    Can I just connect a 12V LiFePO4 battery to the DC input of a solar generator? Do I need a DC to DC converter or anything else?

    Lion Energy UT1300 at Costco again, why buy them?

    It's not just the warranty. It's the lifetime charge cycles. LiFePO4 is 3000-5000 to 80% SoC. Lead acid is...300? There's also the half the weight and size benefit. If you do the math based on life expectancy, LiFePO4 is actually cheaper if you can such up the initial cost.

    Solar charge controller calculator

    Thank you again. I guess I'll be upgrading my SCC.

    Solar charge controller calculator

    Thank you. I wasn't able to find that online. I entered -80 (or -90?) on the calculator for the V temp coeff and that's apparently incorrect because all recommended SCCs disappear from the list once I do that. Does PV Module temperature [°C]: just mean to enter the lowest and highest possible...

    Solar charge controller calculator

    I want to do a big upgrade to my little RV solar setup. I bought 4 Lion Energy UT1300s. Trying to figure how many panels my Renogy Rover 30A can handle or if I need to sell it and upgrade. Here's the panel specs. I don't understand what this calculator is asking for the Temp coeff & PV Module...

    EcoFlow DELTA 1300 (Plug-N-Play)

    That's interesting but what I can't find is the voltage range for solar. 25A seems very high. 300W is lower than the Delta but no mention of voltage. ? The battery cycle life is way better than the Delta but it weighs DOUBLE! 62lbs. Yikes.

    Lion Energy UT1300 at Costco again

    I was pretty close to pulling the trigger last night. Spent hours watching videos and reading. Went back this morning to grab at least a pair and POOF! They're gone. Maybe Battleborn will have some black friday sales this year?

    Any magnetic mounts for solar panels?

    Going to need more than 6 minutes. :geek:

    Any magnetic mounts for solar panels?

    Since the rigid panels I'm looking at using have an aluminum frame, I was going to add some standard solar panel mounting brackets to the panels and then attach a ring shaped magnet to each one. With the magnets being secured to the bottom of the brackets, they'd hopefully be little shoes that...

    Solar panel math help

    Lets take a panel like this for example. Here's the specs: Max. power voltage(Vmp): 18±5% Max. power current(Imp): 10±5% Open circuit voltage(Voc): 21.6±5% Short circuit current(Isc): 10.5A Series fuse rating: 15A Max. system voltage: 1000V DC J-Box IP Rating: IP65 If I want to use a panel to...

    Any magnetic mounts for solar panels?

    I have a gazebo type structure over my BBQ and I want to add a couple 200W~ solar panels on top. It's a solid metal roof and I don't want to drill through it. Wondering if some type of magnetic or adhesive mount exists.
