Oscarel,

If you still have the shrink off can you take a pic of the other side of the SF300lite?

Thx

Here you go

Is that thing coated with clear epoxy?

They're coated to make them water resistant, not sure what they use.

So the whe thing is coated? I didn't want to cut the shrink off and void my warranty but if it's not coated I'll coat it anyway.

The whole esc appears to be lightly coated.

And here's how I wire mine (part of what I do but I'm sure you can figure out what I do.

The coating is called a conformal coating. They are commonly used to insulate electronics. There are Silicone and Urethane based conformal coatings plus several other specialty ones. Most hobby coatings are silicone based.

On my 1p setups, I brought soldered both wires into the connector end of a female 8mm bullet, then a short wire out the other end, along with a pigtail for the caps.
On the 2p setup, I soldered each wire into it's own 8mm bullet normally, then stripped the main wire an inch or so back and piggyback soldered on wire that jumps from one to the other. This jumper wire was stripped in the middle and soldered to the cap bank. I'll see if I have any pics when I get to my computer.....
These have worked well for my applications.

1p
2p

I know the pigtail methods are not perfectly ideal because they are not directly on the power wires, but I have plenty of headroom on both the capacitors and esc., and this was far more feasible for the space i had to work with. The 2p setup has run flawlessly for a few seasons in my Sniper 45" @well over 225 amps, the 1p setup is in the KBB45 twin, and has only seen about 10 runs, but was good enough to break 100mph on gps @ 160 amps.
