Help! Can't get Nano Biscotte setup to work!

[Callas]

After trying about every v2 wiring diagram I could find, I simply cannot get it to turn on, no light, sound, anything. The only change I notice is that the biscotte starts getting hot, and then I immediately disconnect the battery to prevent any damage.

My parts are as follows.

Panasonic Li-Ion 18650 3.7V 3400mAh from TCSS
Recharge port from TCSS
TCSS premium speaker
12mm AV switch
5w Cree led module
Nano biscotte

Thanks in advance!

Well, one thing is the soldering looks like it needs to be cleaned up, you could have a bridge between 2 pads. I also don't see a resistor on the main LED.

[Callas]

There definitely aren't any bridged pads, and the led is rated for up to 4.5v without a resistor. So I didn't think it would be a problem.

Well, if the battery is fully charged, it should work. I would really redo that wiring, and instead of trying to get 2 wires onto the pad, make yourself a "y" out of a couple of wires and try that instead. Also, your wires are cut too long on the pads they should be maybe 1/8" long tops.

Is the battery charged up all the way?

[Callas]

The long wires are really just for test purposes at the moment. I won't be loading everything into my hilt until sometime next week when my chassis is finished being 3d printed. I will try the y-split in a bit.

I'm assuming the battery at least has a bit of a charge since I just received it from TCSS yesterday, and it at lest has enough juice to make the board hot. The only option I have to recharge it is the recharge port I have wired into this setup. But it doesn't really seem to be working since the green light on the charger hasn't changed.

I would charge the battery directly wight he charger, that is if you didn't cut off the JST connectors already.

[Callas]

Unfortunately, I already cut off the connectors..

Also, does anybody have any idea why the biscotte is getting really hot whenever I connect the battery?

[Obi1]

Electronics getting hot is mostly always due to high currents flowing, in this case I guess somewhere where they are not supposed to. Looking at the soldering, I assume the thick red and blak wires are for Bat+ and GND. It could be an optical illusion but on the pic they look like touching each other. Did you check with a multimeter? Maybe even if they are cleanly separated, I would check the voltage difference between in on and off states. The voltage should be ~3.7V. This same voltage should be present on the LED+ when swicthed on (well, even if switched off I guess). Just some ideas to check, good luck!

Unfortunately, I haven't even been able to get it ignite even once. And the black wire is going to the negative pad (not lux negative) since this is a v2 and doesn't have a GND pad.
