Ok thank you guys for the reaponces!

In my E-skate 10S4P pack some welds were damaged by extreme bending ( Car incident), at the time only enclosure was damaged , but after a few rides a Power problem occured. I took battery out and discovered the damaged Welds on 2 of the 4P Packs out of the 10. I disconected those 2 pack from...

Lets say i had 10g copper wire conductor soldered the nickel strips.

Is this diagram , colors represent current and Heat. In this diagram where the wires are Red will also augment their resistance correct ? ...Will their Higher resistance at red points change the way Current flows through the Pack ? Will More current flow through batteries where heat is less (...

I mentioned "assuming connections can handle load". What i want to know is how is Current flowing through the cells,... flowing relatively equal or is one getting much more current than the others ?? Like in shematics on page 1.

How would this rate for current flow, assuming connections can handle load.

How would this rate for current flow, assuming connections can handle load.

But copper is much less conductive than copper ??

Some bullet connectors are made of Brass,.. some of Copper. Some gold plated some not ? There must be differences in Resistance ?,.. which are better ?? Copper is much more conductive that Brass, people never seem to talk about what there made of ,.. does it make a difference ? Where to buy...

?? E-toxx.com

If they are high quality i will be buying some !

Ohbse can i ask at what Voltage your 30Q were delivered ? I recieved my 30Q's at 3.447-3.449 V .

Ok thank you !

All these popular 18650 cells we use for e-bikes or e-skates like the HG2 or 30Q,.. are they protected or not ??

Presice to 1/10 of a volt.
