    Has anyone built a waterproof solar to battery portable setup?

    Good discussions and I learned a thing or two here, but... I'm sort of concluding this is not a solar issue, or at least one solar is going to do anything for. The OP hasn't of yet come back with power requirements for his CPAP, but I googled a few and it seems like 1A at 12 volts DC is on the...

    Powering a 12v Trolling Motor

    You actually gave me a good lockdown research topic! Thanks! I found some research from a university in Belgium on the Peukert effect, and how to modify the equations to determine state of discharge given a load, time, and a Peukert constant for the appropriate Lithium chemistry. So, while...

    I wanna see that diesel generator in that kayak for sure!

    Has anyone built a waterproof solar to battery portable setup?

    I had to move it out of my way this morning, and it reminded me I have it. https://maxoak.net/products/maxoak-k2-50000mah-power-bank It's a 185 wh laptop power bank. It needs 16.8 volts DC at 2.5 amps to charge, and you'd still need a small charge controller for your panel. At the 7-10 watts...

    Battery Fuses

    I like to think of a fuse as protecting everything downstream of the fuse. Each cell in a battery can be fused, as can the output of the battery. Each component in the downstream system can be fused. Each fuse needs to be sized according to the maximum safe current draw of the next component...

    Powering a 12v Trolling Motor

    A battery's capacity decreases as the rate of discharge increases. The Amp Hour rating of a deep cycle battery (going back to Flooded lead acid days) is stated at a 20 hour rate. So, for example, a 12 volt, 100AH rated storage battery can deliver 100 amps if discharged uniformly over a 20 hour...

    Finishing attic

    This is the best advice the OP is going to get. Just lay a path for the cables then determine what you need when it's time to do the solar thing.

    Insulated battery box: incandescent bulb for heat good idea?

    LEDs of nearly any "incandescent wattage equivalent" are a non player as heaters. The reason 100 watt incandescents were used as heaters was that they are 10% efficient as a light source (meaning 90 watts of their consumption is waste heat - about 300 BTU/hr). I've got 300 watt equivalent LEDs...

    Insulated battery box: incandescent bulb for heat good idea?

    9.372 bazillion rural folks in the U.S. use/used 100 watt incandescent light bulbs in their well houses/covers (the high-tech rednecks put them on a thermostatic switch) to keep their wells from freezing. When it was announced these supposed energy wasters would no longer be made, there were...

    Has anyone built a waterproof solar to battery portable setup?

    You did say January in your first line, didn't you? Maybe you could put the Jackery in the foot of your sleeping bag at night to keep it warm enough to charge in the earlier morning.

    Ripped off or I’m missing something?

    Sounds like it's time for a good old redneck capacity test. Grab something with a known draw, like a few old school incandescent automotive brake light bulbs, and see how long it takes to drain that battery at a constant draw. That will tell you its capacity as you have charged it. As another...

    Has anyone built a waterproof solar to battery portable setup?

    I just posted my Physics 101 reference in another thread so won't repeat it here. Heat my friend, heat. How will you control the waste heat from a charging battery? Slathering everything up in silicon helps with water intrusion, but then you have nicely sealed boxes with no ventilation to let...

    Super Capacitor

    Other countries use OUR internet? Say it isn't so! Sorry to jump off topic, but you reminded me of a pair of Bolle sunglasses I bought at a French gas station (petrol station to you) for 30 Francs (maybe USD 6.00 at the time). Back in the good old USA, those were $100 sunglasses.

    Super Capacitor

    This is a good example of a response I was formulating. In Physics 101 (back when we solved complex mathematics with paper and pencil) we learned there was no free lunch, and every machine (electrical, hydraulic, mechanical, electronic) loses some energy as waste heat. Work factor I believe we...

    Critique my proposed build

    It sounds to me as if you are looking at a solution prior to clearly defining your requirements. I think a few people have already said test, test, test before you look at buying anything. Is it possible you can park your camper in your drive to monitor its power requirements daily over a...

    All in one system for a teardrop trailer

    In a teardrop trailer, of course individual components are the way to optimize space. Do you have the time, skills, tools, or knowledge to build your own? One of my use cases is to have AC outlets in my pickup. My Bluetti EB150 fits really nicely under the back seat, and it was unbox...

    Bluetti fan noise?

    You sort of answered your question already. It's subjective. FWIW, I do not consider mine to be loud.

    Solar panels for Bluetti EB 150

    OK, here we go. My EB150 manual says 500 watts max solar input, 16-60 volts and 10 amps max. Period. End of story. Error code E017 will be triggered by an over voltage condition on the PV input. Nothing states what that value is, so I'm going to go with the manufacturer's guidance. Is...

    Running lamps and small appliances from Bluetti AC200 through wall outlets

    Yes, not to mention the safety hazard of connecting a power source to an outlet with two male plugs.
