    Max series fuse rating on panels??

    What does this rating mean? I found some cheap used panels 230w 37.8v nominal voltage and 7.8amp, but the max fuse rating is 15. Does that mean I can only put 2 of these in series? I need minimum of 3 to hit my charger minimum voltage, 4 would be better.

    Also throw the leads away and make some with heavier wire and ring terminals to put on the screw portion not the plug in ones. My voltages changed dramatically after I did. Oops you already did that, getting ahead of my reading

    I have a different branded name of that same power supply and I'll tell you mine runs 1 watt higher then I set it to. Take the charger off for a while and check the voltage with a good multi meter. To make sure it's acurate

    2 280ah cells overcharging

    I had them clamped really tight in my boxes help in with wedges pounded in. I noticed it swelled some but I didn't realize how much untill I tried to pull the wedges out to disassemble the pack. Just an oversight on my part. But like I said I was checking them. The voltage on that cell stays in...

    Yes I've been corrected on that a couple times lol. I always forget. It's the only person I've talked to there that doesn't have a picture Speaking of which all my old messages from Amy now has another girl's picture and name on them. I wonder if she's not working for that other company anynore

    2 280ah cells overcharging

    All my cells read exactly the same when I started charging them gazoo. I watched them diligently thru the whole process and they were all fine right up untill the end it took almost no time at all for that one to jump up that high. The other one that wasn't as high shows no problems maybe that...

    I've watched several videos on youtube now testing these cells that come in over 280. I can't load test kine as one cell is bad so I can't get them charged fully it keeps kicking me out when all the other cells are at 3.35. and I don't trust it's capacity either. But they're sending me a new...

    It's official that cell is bad. It's the one that registered so high the first time I charged them and now I just recharged the pack. I can't get it fully charged. Once they get about 3.35 then that one swollen cell just jumps up to 3.7 and kicks out the bms. Then it drops back down. Try it...

    2 280ah cells overcharging

    I hit the bottom of my invertor setting about 4:30am. That's 14 hours. 8hours of the ac in constant and another 6hr of the ac and a space heater on high. (I wanted to know how long it would run just my ac but my bedroom was too cold to sleep?,) I had a few cells stay higher then the majority...

    I agree that's why I won't use it again. Plus it has a habit of making a bead around the top of the threads as you screw it in and it's super easy to get a film of it over the terminal from that.

    Two overkill solars. Two 24v banks in series I'm looking at daly smart bms 16s 200amp. It just is a bit of a hassle having two different bms apps to keep switching between

    New Supplier for 280Ah cells: Shenzen Basen

    I started load testing my cells today. So far that swollen cell isn't acting any differently then the others. It's been running my AC for 3 hours. I had wanted to see how long it would run the ac alone but it decided to turn cold and rainy today on me. My bedrooms about 40 degrees with the air...

    Actually they're screwing us all on shipping. The Chinese government subsidizes shipping so it's basicly free for them in the end. Least that's what I've been told, I'm no economist.

    Yea that's the stuff. I forgot to order double buss bars too and I had this laying around so I used it to paralel and top balance my 16 cells.

    I meant copper, don't know why I said brass. Probably because of all the plumbing I've been doing

I bought 1/8inch by 3/4 brass bar stock and made my own buss bars. They don't send enough to paralel unless you specificly ask for...

    Finally got all these top balanced. All within .004 anyways. But I did have one swell up pretty good. I don't know how much of this is normal or not. I had a heck of a time getting the buss bar off it I'm going to put a load on them tomorrow and check what they do.

    I think all except the special electrical loctite causes problems. The thinking that the contact with the flat pad is where you're getting your electrical connection. But still I think any extra is better. Plus you can't check voltages off the end of the studs with your meter.

    I made my bus bars out of 1/8" copper. I filed them all flat then sanded them. But I'll check them. Alcohol isn't a bad idea I used lock tight and maybe I smudged some on them. Maybe hit the faces with an emory cloth too I'm actually wishing I had not used the lock tight now. But that's another...

    EVE-280 cells should these be clamped tight or spaced for expansion?

    I was going to build a 16 cell box. Glad I didn't lol. I'm going to make some new ones, maybe on wheels. These have to fit into boxes to ship over to the Philippines and these 8 cell boxes may be a bit too heavy I don't want them to destroy the boxes. I was thinking of lining the inside of the...

    They were fully charged to 28.8 that's 3.6x8 so I figured that's where I should charge the pack to.

    EVE-280 cells should these be clamped tight or spaced for expansion?

    I'm going to put lexan on them. I underestimated how heavy these buggers would be. I may build a new heavier set of boxes with heavier handles for sure

    2 280ah cells overcharging

    I'm only home on weekends so when I unboxed them I paralleled them all and started charging at 3.6v 10a. That was one weekend and they only went from 3.295 to 3.301. I changed them 1 day one weekend and 3 days the next weekend to get to that level. So the 3rd weekend I put them into 2 24v packs...

    Of the 16 cells I bought from Alex at basen I may have 2 bad. I balanced them all by paralleling them about 2 weeks. Then after trying to charge them paralleled for a whole weekend the next weekend I put them into 2 sets of 24v and charged them. When I attached my bms to each I have 3.4 ish...

    EVE-280 cells should these be clamped tight or spaced for expansion?

    Mine may not be as pretty as the aluminum ones but I'm a wood guy. I built boxes just wide enough for 2 cells snuggly. Then an extra 2 inches beyond 4 cells deep. I cut a spacer plate and 2 wedges just tight enough to tap on with my palm when the cells were new and not charged up. Bms is...

    New Supplier for 280Ah cells: Shenzen Basen

    I have 1 cell I may have a problem with but I'm not sure yet. I had my batteries built into 24v packs just getting the bms and wiringnall sorted out while waiting on a new power supply. They were not top balanced altho all read 3.295v. when the power supply came in I put it on 28.8v and started...
