So it begins...... Battery spot welder

When Soldering the Amass XT series connectors( and there are a lot of xt60 fakes) and they are often already on the Chinese  assembled batteries, Don't forget to put the tailcap over the  wires first, although some prefer heatshrink. 

Mate the male and female connectors to Keep the pins aligned through the heating and cooling process.  The Nylon is pretty resistant to melting but.... it is good preventative medecine.

There are little XT30's too but getting 14awg wire onto these is a bit of a challenge to do cleanly.   They are a nice small connector though.


My 7s2p 18650  enclosure with the White booster has a Mosfet based Antispark switch like this.  It's  actual pushbutton is a latching switch.

I think these have a very small parasitic draw, well below my ability to measure.

My 7s2p is only 103.7 watt hours.  I keep thinking about ways to fit more capacity inside this portable battery to battery charger, but then remember I have not even bothered using it, except to test it.

My 3S4P has 222 watt hours and the white booster attached to heatsink takes up the same amount of space, but there is some fragility involved.
