in these T/C-x jobbies that's got convenient self-piercing technology in it!

Too big! 14mm thick that guy. Probably end up interfering with the JST XH connector too: 74's about 9mm longer than I'd go.
Nah. The cold solder blobs are pretty blunt.
I didn't measure mine. Just mental estimation off memory/not caring and picking a ridiculous capscity. One could easily deleter the jst or solder in a jst cable and wrap it around from the front of the PCB.
Definitely easy and cheap to upgrade that little 300mah jobbie though.

Ol cannabis cigarette victory here likes to brag. Too thick, they say. Too long, they say. Nah. He gon' make it fit.
Sheitteeee. I can't talk. Mines two dimensional.

@Stickman393 I actually checked out that 1100mAh battery that’s in one of yours- people are complaining it doesn’t hold a charge… doh! I was gonna snag one. Have you noticed any major differences in the battery life of your two TC1s?

Honestly? The big battery does last longer. Never knew why before.
Batteries are...eh...fickle. You might see that there's a protection circuit board that the leads are soldered to on all of these: this disconnects the battery once it reaches a certain low voltage state in order to prevent over-discharge.
Most common issue with these is that they end up in a drawer when they're dead, then someone goes to change em up...suddenly the battery can't hold much of a charge any more. You can't drain these until they're flat: they *really* don't like that.
I wonder if some of those reviewers may have treated theirs badly, or perhaps they were simply held in storage for too long and not sufficiently pre-charged.

I meant if some king spanner went in there, installed Sr Chungus, and put it right over the connector plug and transformer

Believe it or not, the TC-1 is far and away the better tester.
Try this with the LCR: insert an NPN transistor. Test it and see what the pinout is. Now take it out and flip it. Test again. It’ll likely be the same pinout. They’re aware and evidently unable to fix this bug after several months- which is weird since the TC-1 has no such issue.
The LCR-P1 has also given me wildly incorrect capacitor readings. It’s unreliable. Honestly, I’d return it.

Just bumping this in case anyone - new or seasoned - has considered the LCR-P1 over something like the TC-1.
Don't!
After numerous firmware updates, the device STILL does not correctly determine the pinout for NPN transistors. It may have other bugs too.
that bug is now finally fixed with the new firmware version 1.1.0 here is the link: https://drive.google.com/file/d/13kKBeBr3GHwUjKFLNVBx1N_cnpt_mEeQ/view?usp=sharing
this version is not present in the website yet, it was sent by Fnirsi support by email.
