they work better in low humidity areas but they also work in other areas. This shows the post of using a large swampcooler in high humidity areas. Sometimes we encounter "el nino" in southern california where the temperature and humidity is very high, and the small swampcooler I have I run 24/7...

For the van you have to downsize your power needs and use 12 devices as much as possible. An AC even the 24 volt zerobreeze (runs on 24 volts / 10 amps 240 watts) a jackery 400 (400 watt hours) won't even run it since its 12 volts. Heaters are even more power hungry 1500 watts. The portable 120...

From what I can tell your batteries aren't being fully charged. Lifep04 requires at least 14.4 volts, I always charge mine to 14.6 volts. Your victron shows the max voltage reached was 14.16 volts (which is insufficient). The mfg recommends charging at 13.6 to 13.8 volts which most chargers...

Sell it, they are easy to fix and get back running. My 1986 astrovan is still running like a champ. Astrovans that are still in running condition, I see in craiglist for 2 to 3 grand sometimes even higher.

if your talking about a power station, you just plug it in the wall. You would have to find a place that has an outlet where you can spend several hours to charge it. I use to go to the library and spend 3 or 4 hours charging my laptop. There are many portable power stations available, try and...

which meter do you have? I been using the TK15 for years on my 220ah lifepo4 and has been very reliable. But any coulombcounter has to be properly calibrated the first time or the reading will be off. 10 volts while low for a battleborn won't damage it longterm, the voltage range for an...

I been using the 4x8 foot rtech 1/2 inch foam from home depot. I cut into small sections and hotglue it directly to the bare metal ceiling no air gaps. On the roof I have several layers of foam, hotglued one on top of the other, 3 to 4 inches thick. Once its thick enough you no longer feel heat...

On the roof of my van I removed the headliner and just added rtech foam to the bare metal. I started with 1/2 inch, then went to 1 inch, 2 inch and finally at 3 inches of foam insulation I no longer felt any heat coming from the roof. (hotglued in 1/2 inch layers one on top of the other) This...

I use my 12 volt roadpro lunchbox cooker for heating up soup or anything else that comes in a can. It will heat up soup in about 15 minutes (uses anywhere from 9 to 11 amps while on, about 4 amps total during the 15 minutes). I also use it to heat up water when I want to eat cup of noodles. I...

I been using swampcoolers for the past 10 years, many times 24/7 on hot days. Never had any moisture problems, nothing inside my van has rusted. For me moisture or dampness etc is a non issue. The only time I ever had moisture problems was when I was using a mr.heater, my windows in the front...

The charge amps are good, I think the battery is very low and since its not getting up to 14.4 volts it means more power is being used than being replaced. Your only going to get up to 14.4 volts if its charging while no loads are being used by the battery. On my system if the controller is...

The bms should be OK, it won't cause any draining of the battery. You mention the weather is hot, the fridge running more than usual. About 3 years ago in very hot weather with the fridge running more, having to run 2 swampcoolers to stay cool and also my roof vent, after about 2 weeks my 240...

you need an AC charger that plugs in to the generator or shorepower and outputs what your battery needs 14.4 volts for lead acid or 14.6 volts for lifepo4. If you have a giant lead acid batterybank you can use a charger like they have in auto mechanic shops but those are large. Here is a...

I only had 1 fire with lithium and it was a lifepo4 cell, I accidentally shorted one out and it punched a hole on the side of the cell. When it went off it was like a blowtorch. Luckily I had a small bottle of water and was able to eventually put it out (actually it ran out of pressure). The...

I think 15 amp fuse is too much for the joytutu fridge. I have the same 26 liter fridge and it maxes out at less than 6 amps when the compressor starts (less than 4 amps after it starts) when used with 12 volts. When I first got it, I had problems running it from my lifepo4 system, if the...
