Searching today for angled lugs and twisted busbars I discovered this YouTube video. Sounds like it is an acceptable practice to use the method you describe and the end result may be better than stressing the cable with sharp bends. (Not sure about that since I'm not an electrician, but it makes...

Hmmm, I have no previous experience to gauge the fit. I wouldn't say the match was "tight" since I could rotate the connector over the wire strands with no problem, but I wouldn't call it "loose" as in sloppy. It seemed to match well and fill the socket. The wire gauge designation matched the...

I'm using Windy Nation 2 AWG welding cable and Anderson 2 AWG lugs from the Powerworx SB175 kit. The crimper is a 12-ton hydraulic crimper that was $70 on Amazon [marked as "AMZCNC Professional Hydraulic Crimping Tool with 12 Ton Output Pressure and 9 Standard US Dies (Crimps 8 AWG to 4/0...

That makes sense. I'll avoid sanding things down in the future. Today's efforts fit much better w/o any sanding. Thanks.

Here's a link to the Ecoholics webpage that discusses how to maximize solar charging for Ecoflow power packs: http://www.linspyre.com/ecoholics/maxsolar.html?fbclid=IwAR3pOkobtGVhaNzIQw6bZ72PyjWvxWoiE_Jc7UCNu2xVixjRY1sjC1ih7Nk Yes, my limited (and beginner) understanding is that series adds...

Thanks for your input. I see that Temco sells individual die pairs for under $20. That may be the path I should take to see if they fit/work in my crimper before spending between $90 to $150 on something that I'll have very limited use for. Some of the dies I already have may work well enough...

OK. Thanks. I assume the fuse would be sized to the smaller wire? As for the 6awg links, each charger will have a circuit breaker between it and the positive busbar. I just didn't detail that section in the diagram. I assume those breakers (60amp or 50amp depending on the charger) will be...

Got it! Thanks for the explanation. I appreciate the time you took to answer my question.

Fellow newbie here. I went with a Chinese 12-ton $70 hydraulic crimper off Amazon and now wish I had put that money towards the Temco hydraulic crimper...

Thanks very much for your explanations and recommendations. I'll pick up the Temco one you have. It looks like it will cover all the large crimping projects I may be doing. I think you've identified the variables that caused the problems I was having. I attempted a few more connections today...

The specs show the open circuit voltage (voc) to be 20.3v per panel for the 100w model. The Delta 2 has a maximum input voltage limit of 60v so only 2 panels could be wired in series for that unit. A third panel would give 60.9v. Also, the voc rating is for ambient temperatures around 70F...

Not sure this will be helpful but I have the same battery and am doing a DIY build using a Ridgid Gen 2 XL rolling toolbox. I chose that particular box because the 12v 230ah LiTime LTCP battery fits vertically in it nice and snug because of the side support rails, but the primary consideration...

Thanks for the link. I just measued the dies I have and the Temco set isn't compatible. Looks like I'll have to purchase the Temco crimper and die set. I wonder if local electrical supply companies might rent them.

OK. Thanks again for the confirmation about the quality of the cable I'm using.

Thanks for the feedback. I'll try a slightly larger crimp die initially. Also appreciate the tip about rotating the connection to flatten the wings rather than sanding them down. One of those "I wish I would have thought of that" moments for me.

I'll try a slightly larger crimp die for the initial crimping. That seems to be the general recommendation so far. Then re-crimp with the smaller die as you suggest. I appreciate your feedback concerning the insulation and orientation of the resultant wings. Thanks.

For my DIY power bank build I planned on utilyzing large Anderson SB175 to connect between two separate toolboxes (one housing chargers and the other holding a 230ah 12v battery and 2000w psw inverter). I'm using Windy Nation 2AWG welding cable and some Powerwerx #2 Anderson connectors for the...

I bought a couple Ecoflow Delta 2 power banks (1024wh each w/1800w inverters) back in November 2023 along with a pair of 220w bifacial panels to use while camping. I was so impressed with them that my curiosity piqued and I started to think about building my own, higher capacity unit. I...

Understood regarding sizing the fuse to the wire but does the BMS number always indicate the maximum continuous current to plan for or is it just a coincidental match (200 BMS and 200a continuous current even though the battery is rated 230ah) in the battery I purchased? IOW, do I never need to...

I'm trying to put together a portable DIY power bank system for camping and I'm confused about the maximum amperage I have to plan for going through the cables. I've read various posts about sizing cables based on various ampacity charts and formulas, but many of them give conflicting results...
