Paint the container white, big fan and yard shower. If you have AC turn on an hour or 2 before sunset and run as long as batteries will last. Sounds like a seasonal camp.5000 btu is small for what you're doing
Four in parallel for a 12v battery charging at 14v at a little under 10 amps probably more than twelve hours. Monitor every cell and turn off charge if you need to go somewhere.
What about the money he made on these damaged cells. He could refund that as a good will gesture while people wait for final outcome. Michael doesn't deserve a commission on bad cells. He can refund money on orders not yet shipped.
This isn't a group buy. This is a business for profit. Michael made a profit on. The cells in question, that profit needs to be returned. He didn't earn it.
Where you at Michael,? This what he said.
Guys, I bought a bunch of them and paid up front with my own money, taking a chance that they would all move. I did not buy all of them available as I was not sure if everyone would be cool with cells from EV packs that are technically "used" even though...
I'm obviously not finished . It fit in a little playmate cooler. Need to add fuse and a few different plugs. Perhaps a cigarette lighter if I can find a decent way to mount it. Trying to make it with things laying around. I use less than 100 watts for what I power.
I went with a iceco compressor cooler on my boat. $500ish. So far I like it. 200w of panels and some old lead acid batteries runs the whole boat.
I have the same iceco cooler. Works good.
This paragraph is telling what to expect from supplier.....
I can also tell you that, from experience, I do not believe you will find any of the suppliers that are as willing to replace shipping damaged cells or runners. My experience as that they would offer insultingly low refunds on those...

I put a switch between my aims charger and battery. On some review someone mentioned it has a parasitic draw. If you have a DC clamp meter it would be easy to check.
Looks fair to me. The convenience of not having to wait 3 months for delivery from china is a major plus. Search reviews for that particular battery. I'm building a 230 battery and after buying the parts I'll have about $600 into it.
Does your bike have disk brakes? My brother had 48v rear wheel drive. Very fast and could pull wheelies. Problem was the wheel friction brakes didn't hold up to job. Stopping quickly was terrible.
I'm a boat guy. A bilge pump runs maybe ten minutes an hour in downpour. 50w panel should be plenty. If there's a chance of waves the bow needs to be facing out towards the waves. Waves will swamp the boat if the stern is facing the waves. Personally if I had a camp and boat I would make or buy...
Things have changed since you ordered batteries. I placed my order in the group buy February 11 and they have not shipped yet. I'll be lucky to get them by July.
Found this....Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.) My batteries are on a boat in humid climate.
I had a 40ft boat similar to photo. Two 3208 cats. Two miles per gallon at 8kts. You have the wrong hull for electric. You need two engines for control in tight space if there's any wind.
What is going to hold the cells together? The bus bars and tape? With smaller cells compression is not as critical. If you ever need to move the battery you will need some sort of compression. The strain on the terminals if or when the cells swell could be enough to cause problems.
What is the average humidity at your location? Is it high enough to make enough water? One 100 watt panel is not much power. I would guess you would need 400 w at least.
I have been looking for something comparable to the aims converter charger with no luck. The adjustable current is what I want so I can charge different batteries at different rates. The AC input is very forgiving so good for generator power. A 30amp charger is not going to cut it on a large...
I'm trying to buy that converter now. It is out of stock everywhere. I'm considering ordering it from Missouri solar to lock in the $229 price. It will easily run on your generator. Some have used 1000w generators and turned the amperage down to 50amps and it works. I think you need a switch if...
Perhaps try it from a similar elevation with a generator to get idea of the volume of water available. If you use a kil-a-watt meter between generator and dehumidifier you can see how many watts per gallon and go from there.
Is this a mobile unit? If yes then it looks like they will eventually come loose. All that holds then together is the little bit of foam and the bus bars. I think you need a smaller box and better design, At least tape the cells together. Good luck
I didn't use a BMS but I watched carefully and checked each cell to make sure none went over 3.65. Once they approach 3.45 the voltage goes up quick. Be careful how ever you do it.
1 solar panel on the roof would be more discreet than an extension cord. My compressor cooler is very efficient. You could probably get by with 100 amp battery and a hundred watt solar panel.
Yes you can and it will speed up the balancing time. If you don't balance it will trip BMS with one or more cells going over voltage or under voltage. This will effect the usable power your battery can supply. A bench top power supply ($50ish) can balance one cell at a time. Set voltage to 3.65...
You will probably be fine with either controller. That said I would try a mppt. My no name pwm controller and 200w of panels is producing 60 to 80 amps a day at 12v. I'm considering the rich solar controller at about $80. What batteries do you have?
I have a similar setup as you. 200w of panels compressor cooler, fan and 12v TV. My system just makes enough. Not an expert on charge controllers but I think you will be ok. Perhaps consider the shunt type battery monitor so you know the status of your battery level. Hopefully an expert will...
Victron has a 9amp battery to battery charger for $65 . That's the 12v to 12v. The 24 to 12 is probably a little more $. Look on Amazon. A 50w panel would probably give you 10 to 15 amps a day@ 12v.
