Hi there my friend I have a question in this batteries that you're using in this video , what's the output amperage? And what's their nominal amps per cell , you using the 3.7 volt 5 ah or the 27 ah? If so can u tell me how much amperage delivers the one that are only 5 ah and also the 27ah ,am trying to see which ones to purchase, I ordered the mosfet switching boats while back I haven't use it yet, but then I saw your other video where u started using 2 conectes in series's,I was just wondering how much output amps u get with this set up ? Please and thank you

Master Yousun, thank you. The weld result is great, not too much of sparks seen @8.4 dc what sort of Battery are you using. Looks like Lithium Polymer stack. There are 2 Battery packs. Why? What are those MOSFET Board? Would you be able to explain, please? If you are planning to assemble and sell, I’m interested. Please let me know.

[@yousun2827]

Powerful battery for spot welding energy, The MOSFET Board acts as a switch. www.yousun.org/product/spot-welding-3-7v-5ah-lithium-ion-battery

How much do you get time in ms for welding 0.3 mm nickel? I have the same battery, but a 0.3 mm tape is very welded. Probably the wires in me are inadequate.

[@yousun2827]

0.3mm nickel, Full power 60ms.

[@urez837]

Thanks ! And I think why he does not weld at 15ms.

[@yousun2827]

The energy is not enough, the higher the energy, the shorter the time.

[@urez837]

It is natural. A little later I'll buy you an electrode holder. My holder with wires has a high resistance. I have 18 pieces of the IRFP2907.

[@yousun2827]

OK! 0.3mm nickel 18pcs IRFP2907 is not enough.

Is that the 36 mosfet switch in this video?

[@yousun2827]

72 mosfet switch.
