Podsumowanie budowy Magazynu Energii - Koszty + uzupełnienie materiału

Due to the high level of interest, I decided to add answers to the questions from the previous article. I hope the information will be useful :) Below is the cost estimate. I spent about 4,000 PLN on the project, but unfortunately, prices are different now, so I decided to do it at current prices on Allegro. You can look for a better price, or buy from China, like I did, look for promotions, etc., but this description will give you an average idea of ​​the costs: 1. Cell cages (x4 slots on nickel-plated plates - 7.83 PLN each) 210 pcs - 1644 PLN. 2. Fuse Holders (PCB PTF/15 – PLN 5.50 per 10 pcs) 840 pcs – PLN 462 3. 5x20 Glass Fuses (4A – PLN 9.2 per 100 pcs) 900 pcs – PLN 82 4. Copper Flat Terminal (+/-) (3x25 PLN 47 per 1 m) 3 m – PLN 141 5. Copper Wires 2.5mm² (3 x 2.5mm PLN 10.2 per 1 m) 20 m – PLN 204 6. DC Wires 35mm² Red + Black (PLN 25 per 1 m) 10 m – PLN 250 7. Active Balancer 14s (I only found these on Aliexpress) – PLN 180 8. BMS Ant 320A + LCD (I only found it on Aliexpress) – 400 PLN 9. Used ABB 4P switch - 300 PLN 10. ABB XLP 00 manual switch - 100 PLN 11. Bussmann 160A inserts - 300 PLN 12. 3D printing (the designs are mine, also made on my own printer, so only the material cost) - PETG filament, approx. 10 kg - 600 PLN 13. Battery indicators, 14 pcs - 80 PLN 14. Welding plates, 200 m - 400 PLN 15. Insulation stickers - 150 PLN 16. Accessories such as connectors, wires, solder, etc. - 300 PLN So the total cost for the battery section alone is currently around 5,500 PLN, not including the cells, but As a rough guide, a single cell with an average capacity of 2000mAh costs 5-8 PLN per cell on the secondary market, while a new one costs around 10-12 PLN per cell per pack, or 20-25 PLN per cell for brand new ones. Obviously, it's best to source them from damaged batteries or packs; they're much cheaper, but it requires a lot of work, basic testing tools, and time.
