Looks good but how has the nominal voltage worked out for you since 18650 li-ion cells are only 4.2v at full charge but nominal is only 3.6 volt that's only 10.8 for that 3s battery ? I have had to go 4s to 16.8 volts then the nominal voltage is a manageable14.4 volts , my use is ham radio and my radio can handle that voltage but for an inverter not sure which one can take that high of voltage that's why we go to 24 volt li-ion battery and 24 volt inverters .

I didnt see any solder on battery terminals. I'm confused on how they're connected. Please enlighten me

What's the fuse ratings

What is that application you used?

Good morning why not use nickel strips per point and put a bms? That would be easier, right? THANKS

@MakerMan

26 күн бұрын

When it comes to old cell or reused cell , it's always better to use a nickel wire instead of a nickel strip. As there might be some cells getting bad down-the-line and it will not effect the remaining cell in parallel.

Thanks for the Video. What Software do you use to calculate where to put the Cells in? Packer?

Hello everything looks good and great but you know that 18650 and other cells are not soldered but spot welded because the film is made of plastic where the lithium and cobalt is steamed on it, this can cause damage and if the cells have a pressure relief valve automatically by a hiss degas or even burst.

Why Switch to Lithium? Longer Life, No Maintenance, and Faster Charging are just a few of the advantages lithium has over lead-acid batteries. Making it an exceptional return on your investment for years to come. SERVICE LIFE: Lithium-ion batteries last 3-4 times longer than lead-acid batteries without losing effectiveness over time. #lithiumbattery #leadacidbatteries #batteries #maintenance #investment
