Power Modules v2 with removable cells | 18650 project | MakerMan

Here I made a 12v S4 18Ah Modular battery pack with removable cells from 18650 cells salvaged from old laptop batteries. I made a these pcbs for the Power modules, where there are glass fuses to show if any cell is shorted and can be easily serviced. I used my previously made 40cell Charging & Capacity Testing Station to know the capacity of the cells for repacking the cells in to proper battery packs.
I was contacted by JLCPCB, about their interest in sponsoring some of my projects and providing me with pcbs to speed up my projects.

I like your project. You are one of the best!

Amazing work👍

You are so great my friend. ❤

Love your project. You're the best my friend 💪💪💪

[@MakerMan]

Thanks my friend

[@FredddH]

Can i use this for à Ebike or Elecyric Go Kart or just for PowerBank?

[@MakerMan]

Yes, just make sure you are using thick bus bars. My use is just for some small outdoor lights which don't require high amps.

Hi, it's an excellent project. I'm thinking of riding. Could you share the GERBER file? TKs

[@orhantecik8456]

may i ask for Gerber files for this Modular 12v S4 18Ah battery? Please 🙏

[@davidreiners7111]

I love this design and your Modular PowerWall design. I would like to order some of these but I am afraid I am quite dumb when it comes to this. I see you have a link in the description above, do I only need to change the quantity and add my address to order these? Thanks for your help.

[@kyleperkins4757]

Hey there, could you give me the stencil or the file for the thing that you made so I can order it that way

[@pavgup]

Very nice work! Where are you buying the laptop batteries?

[@Teknopottu]

Nice project. Couple of things bothered me though. The board says 12V 3S but you use it as 16V 4S. What gives? What was the minimum voltage of the cells you used? If cell voltage goes low enough, it can become unstable. Thus one capacity test tells you only that, the next cycle can be a lot lower if the cell is not okay. Did you measure the internal resistance of the cells or check the temperatures when cyckling? If the resistance is too high, cell can become dangerous because of overheating.

[@MakerMan]

I initially planned for a 3s but decided to on for a 4s. I only use cell above 4.00 when was tested and charge and stored for a month. I discard cell which gets hot, usually it's the Sanyo's.

[@danhle1032]

what is ur thought process for 3s vs 4s when ur trying to do 12v? 3s is only 12v when each cell is above 4v which is not a lot of capacity, but 4s is 16v when each cell is charged only to 4v, which is a lot of capacity but how many 12v devices can use 16v?

[@ilmartellatore]

Ciao,complimenti,volevo sapere dove acquisti i moduli in plastica porta batterie,se puoi mettere il link,grazie e avanti con nuovi progetti,saluti da Italia.

[@scottmac442]

Great Project, Thinking of building my own! Thanks!! Can I order the PC boards from JLCPCB? For higher Amp I could solder some bigger wire as bus.

[@MakerMan]

Yes, you should solder high gauge wires for high amps usage. I use it only for outdoor lights. Email me for the Gerber file of the PCB.

Hola como esta muy bueno proyecto se puede modificar para un car audio de 1500amp 14.4v

[@MakerMan]

English please

[@MakerMan]

sí, solo use una configuración 3s o use un convertidor reductor.

1amp

Just search in AliExpress for 1 amp Glass fuse
