Hey all, today I had the pleasure of receiving my DC Sabers Jericho, and I'm blown away by the craftsmanship, however it didn't come with a battery and the one I had was too small to fit (needed a protected battery) so I went and bought one (pictured), when I inserted it first it made the boot sound and the light turned on, but wouldn't stay on and powered on intermittently, I noted a faint clicking noise coming from the speaker and nothing else in terms of response from the saber. I figured the battery may had just come dead so I charged it, and now when I plug it in and then the Killswitch nothing happens besides part of the core getting decently warm rather quick.

#

Is it the wrong kind of battery? The user guide didn't specify in the amps or volts, so I got this one.

3.7v is fine. The amperage might not be sufficient though. What is it rated for?

Also note the kill switch sometimes has 3 positions, two of which are off.

#

can you specify what part of the core is getting warm?

It does have 3, is the middle one off? I figured all the way to the right is on

rapid dirge can you specify what part of the core is getting warm?

Seems to be on the side just above the positive terminal of the battery

#

Just under the front part of the board

#

Not sure if the actual board is warm I dare not touch it

#

If the board is getting warm when power is applied, that's not good.

#

Well, I say warm, I mean scolding.

#

It was surprisingly warm when I touched it, enough to make me move my hand away

#

Didn't see any signs of heat damage though

#

that's not good. Normal use, some warmth can happen, but if it's enough to make you really notice and pull away, means something is wrong usually, can you narrow down where on the board it is getting hot? The MCU?

#

I didn't get the chance to narrow it, didn't want to touch the board itself as I was worried I would damage it, I don't really want to put that battery back in in case it damages it further

fair. tbh might be time to reach out to DC. Next steps on testing I would normally recommend would require limited power, which if you wanna limit the amount of current that can be pulled you would want a bench power supply which most people don't have.
