Today I have got a deal with a chinese company that assembles battery packs: they will assembly and ship to my house (customs included) 10s4p battery packs for 190€ each (if i buy 10 of them).
WHAT’S INCLUDED? 40 authentic (see FAQs below for more info) SAMSUNG 25R already spot welded together according to this scheme: 10s4p. More precisely the pack will output 36v 10amp/h. Cells are assembled with spacers to prevent heating and to give a structure.
WHAT KIND OF SPOT WELDING? I picked the most expensive and tricky material for our packs: copper. It is technically impossible to achieve a spot weld with copper at home because it is the same material of welding electrodes (which will melt along with the strip). Copper compared to nichel/aluminum/zinc has the less resistance so it drains current with less heat produced. Each cell will be spot welded in 4 points each side.
POSSIBLE ADD-ONS 1)BMS :23eur 2)ON-OFF switch (already tested; will be soldered by me on the BMS)= 2€ 3)LCD with battery percentage= 5€ 4)Heat shrink and awg8 cables: free if you add the BMS 5)(only italian buyers): pay in cash to the mailman: 3€ 6)paypal fee (see FAQs)
SHIPPING TO EUROPE: Only choice: UPS= 15€ to europe (25€ to some countries: Czech republic, Greece, Poland, Slovak Republic, Hungary, Bulgaria, Estonia, Latvia, Lithuania, Romania)
Probable FAQs How do you know we are buying original cells? 1)I ordered from this company 30 cells to test out and they fullfil samsung original specs (dimensions, weight, discharge rate, peculiar manufacturing details)–2)in the deal with the company there is the fact that if I find out 1 cell is counterfait the whole order will be refunded and I keep the goods.
Why don’t you order the final product including cables and BMS already soldered, wouldn’t it be cheaper? Yes it would be cheaper. But this way (with the naked product)I can check the quality of each weld, and each BMS.
Why don’t you just offer the whole pack without stupid add-ons? I don’t want people to pay for something they don’t want/need.
What if I don’t want to give paypal the fee? 1) You pay in friend mode 2)you send me a bank transfer
