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

[sternwake]

So, i  used a razor to cut the sticker over the Zeee's  cover, on one side, and it looked like it had no desire to easily open and allow me to out 200c silicone 10awg leads directly to the cell buss.

So i cut a 2" long Pigtail off with provided xt60 connector, cut off the heatshrink, and the solder joint was far from perfect, but ive seen worse.

What i did notice was, in comparison to the Amass  XT60s i bought, is the yellow housing was slightly different color, and the contacts were not gold plated but plain brass.

So  The Zee Lipo battery came with generic xt 60s only adequately soldered with 12 awg.
i had a closer look at the 38$esk8 xt 60 and it was obviouslyy generic too

   

So I put an xt 90s antispark on the Lipo, and  it should have far less resistance than an actual Amass XT60, much less than generic.

I also wired up the dual battery leads for the red BSW, and put a 10awg Xt 90s antispark  connector on My 22ah agm,  next to dual 8awg 45amo anderson powerpoles to drive the optocoupler that drives the  mosfets.

Then the mail came, and the purple bsw. 
somehow i managed to order the one without an enclosure or leads, but woukd have used the leads from old red anyway,  bjt do miss the acrylic enclosyre.

When checking to see what i ordered,I i saw there was a slightly different purple version, when one spies the circuit board closely.

Not sure if my Mosfets are actually infineon.
Ive not hooked it up yet, nor tested old red with the dual battery feed.

I have a two for 10$ cheaPo led headlight intowhich i installed a larger capacity 18650, but i soldered it, and i think it  drawss the cell below 2.5v too, if i allow it to dim.
so this battery is likely the least safe 18650 I own, and i might frInnit fully and use it as my BSW test cell.

It should really get a protectexd cell withi  it, if it  indeed draws the cell below 2.7v.

I did notice the last time i recharged it from dim, it took far less MAH thaN the last time i measured using the same meter.

my new regular inline wattmeter which doez not save peak amos or watts, does show ah to three decimals, opposed to mynolder wattmeters which have two decimals.

inline they agreed on amp voltage and amlerGe, but did not agree on amp hours consumed.

I dont know which one to believe, and will have to test.  I know the timer on old wms is off and the kwh figure is way off, but using a regukar  clock and a steady current they checked out ok when i got them.

But they never seem to register as much ah delivered or returned as id expect, so wbo knows.
