return and supply lines. :D

Thank you for the update. I can't find the Atian on sale but would still buy one but as you say; I would just be careful. Unfortunately, not everyone who bought one may have known about this safety hazard. Great info and content that you have been creating.

Hi, just got one of these over here in Japan for a 30ah LifeP04. Quick question, when the battery's full does it just display off and not full? Cheers

I have two 30 amp victron battery chargers and love them. I prefer to charge my batteries , slow to extend the life on them and mainly because a weekend warrior and have plenty of time for them to recharge.

Have 4 of the units. Solid when fully assembled. Two people to assemble was easier.

I have that same saw and the ns872. Both have been excellent so far. Needed tuning though

How wide are your panels ?

👍

I have one of those. Not sure I'll ever part with it. Because it is ridiculously unreliable. But it's also unique and an oddity. And it's kind of neat having it for that reason.

Shadow on the solar panels

4:30 oh wow I have that exact same power bank! It'll charge off of basically anything lol

That's good for learning with before you invest in a larger and more efficient systems.

Be ready when your edge slices through your head cover....

Great account and video, hope u get more subs

What's the square footage of your shop

you think i can run the eg4 12000 btu mini split with 2 400watts panels

What does your LiTime charger do when the battery reaches 100%? My LiTime charger, charging a LiTime 100Ah battery, runs for a second or two than shuts off. It repeats this cycle until I unplug the charger. Is this normal?

great update … I didn’t realize it, I’ll test mine later … thx. done testing: it showed 30.64V at the clamps whilst showing “Off” … I have another charger; with its power on the clamps showed 16.64V … the thing is my 12V car battery is showing 14.05V at the terminals … guess the battery on its own is also a safety issue … point is, both chargers should be treated with respect at the clamps when connected to a live power source; same as a 12V or 24V batteries standing minding their own business at the corner … great tip by the way …

Cubic inch? 🤣

Thanks for the update 😮

Have you considered one of the fans that runs from heat on top

Bought the 20 amp Li time charger...spent $94.00. It does a great job charging the 230ah battery I bought from them as well (about 3 hrs).. Wish I would have seen this video...probable would have went with the cheaper one and saved some money..

Redneck that shit up! Looks good bubba!

Check and see what the current is coming out when you see the volts with unit in OFF. It may be sending out a "sense" voltage which is often just a small trickle and may be actually harmless. If it is jumping it is most likely just "Looking" for a load. a floating voltage is common in many applications. Does the Kilawatt show any power being pulled? What is the power draw in OFF vs full charging rate on a dead battery? It does say it is "Smart Automatic Maintainer Trickle Charger" so it is probably doing a float charge regardless if there is a load or not. I agree that is not best as OFF should be completely OFF and not trickle. It should have an OUTPUT RELAY so it can completely isolate aka shut off the output in the OFF mode.

I have 2 of those red ones, both with "Foxsur" on the back like yours. They both do the same thing and, coincidentally, when connected to LiFePo4 battery (ies) also show a wattage draw of 38W on a Kill-o-Watt meter with the charger display reading "FULL" and no flashing of LEDs. It must be doing something.

discovered that resistance is high with those battery clamps and these battery chargers are sensitive to resistance...so keep the charger charging the battery to 100% connection was secured by nut and bolt...and quick disconnects between battery and charger. a good solution for tolling motor/charger/battery.

I use a 5$ buck. It can handle 20a with a fan. Works great in parallel too if needed. Charged a 12v250ah many times using 3 in parallel at 40a. I just charge to 14v. The amp will hit zero when done. I charge smaller ones too, lile 32650 and other. Can set both amps & volt as i need. Got one on my 24v solar pumping out 14v to all my 12v fans & lights all over the house.

Both extremely overpriced. You can get server power supplies converted to CC CV power supplies. 0-15V 0-50A and there is even one that is 0-15V 0-100A. The first one is about $60 shipped and the latter is $110 shipped. There is also a 0-100V 0-20A (0-15A on 120V circuit) charger for $110 shipped.

tap them like a champ :)

Does the top horizontal rail adjust down for shorter panels?

Tell practically how uou made it not viabley😮

Thanks COOP ...

I think it is a "wake up" voltage for LiFePO4 batteries. If the battery BMS disconnected due to low voltage (dead < 9 volts or so), you can't charge it until the BMS sees voltage at the terminals that is above it's disconnect voltage. Many newer battery chargers that are not lithium specific take a voltage measurement (requires no output from charger, just like your voltmeter) to determine charging voltage (i.e. 6,12 or 24 volt). If the charger sees no voltage, it won't charge- useless if BMS is disconnected. LiFePO4 chargers send a voltage to "wake up" a disconnected BMS so charging can begin. Sometimes you can even wake up a BMS with a little square 9 volt battery. Still "Off" should be "off". Bad design.

Perhaps it is a Capacitor discharging ? Be interesting when this Brand answers this question to you . TNX for the Demo and info .

How long does it take to charge 100ah Lifepo4 battery on those charges (10A) in comparison? Also how many watts they take on the input? Thanks

Were your chargers in 24V mode, before getting the 30V readings? My charger was used at 12V before reading 17V in "OFF". There seems to be little to no amperage in the leads. Any load, like a small light bulb sends it into error mode and the voltage drops off. Maybe it is a sensing current sent from the charger to detect the battery condition? Other than this anomaly, the charger works great.

What were the solar charge controllers in the white boxes that you use? And do you use those to charge the Lifepo4 batteries? Thanks.

When my ATian charger plugged in and not connected to a battery, it displays the "OFF" stage, but the leads have a 17V charge. I am wondering if this is normal.

I have the red one branded as FOXSUR for about a year. I have used it to charge a 200ah lifepo4 battery with no issues. I try to charge with solar as much as possible though.

I have 6 of the 400watt panels. Would i be able to buy 2 eg4 kits and just use half of the second one for a 6 panel ground mount?

Thanks for sharing! I've been looking at these. I'm not crazy about the way they mount, I probably would prefer front and rear mounts to bolt them down for more strength, but I guess they work fine as is and this requires less footings. I'm looking for something that's semipermanent, seeing these assembled in your video gave me the idea of maybe mounting these on something like a PT 4"x6" for some ground clearance and not anchoring it into the ground... Instead, use 6 screw anchors (3F, 3R) and then tie them down from the beams. This would be easily (re)movable and be less hassle than digging and pouring concrete, not to mention a lot less hassle than removing said concrete! If you used something like ratchet straps, you could even easily adjust the tilt a little with the straps, lol!

I’m building a 5 panel mount out of unistrut for aprox $200 and I’m mounting two more 5 panel arrays on my metal patio roof with 4 98lb magnets with stainless hardware $15 per panel. This 5s3p arrangement gives me over 1500 watts at 102v and 14.73a in perfect conditions. I using JJN 100w 9bb panels at $59 a piece.
