Looks like we need to bypass that tailcap spring.

Yep, probably do. As maukka said, it get’s pretty hot down there.

[maukka]

Standby current is 170 µA. Two years two drain a 3000 mAh battery.

The tailcap spring resistance is huge, 74 mOhm. No wonder it heats up. Definitely recommended to bypass it.

For reference, that’s 4 times as much as the similarly long spring of the Acebeam EC65.

[JasonWW]

My guess would be that this stock spring would activate the low voltage protection earlier than necessary giving less running time.

Current is pretty low. I suspect the tailcap gets warm because it’s the only place via the metal battery tube to dissipate heat.

[maukka]

Yeah, been running it at (1 amp which is around what the lantern draws) for a while and it’s not very hot. But does get hot at 2 A. If it’s a constant current driver, the current is higher on low battery. Has anyone done runtime graphs yet?

edit: maybe the heat path of the whole thing is directly connected there, since it looks like the whole bottom piece is part of the same aluminum block. The tailcap is just the only place without plastic molding.

I let the light run a couple of minutes with just the usb power connected (no battery) and the tailcap got warm (hot after 10 min). It’s the led and driver heat flowing there. Combined with the battery and spring heat, it’s no wonder then. The whole battery compartment seems to be the led heatsink as well.

If it’s not too late, I’m interested in 2 lanterns once this GB starts up again.

@freeme

Glad you guys like your new purchase. I will feedback to their manager on Monday, and persuade them to proceed with second round soon.

Any updates from them this past week …… :question:

[hIKARInoob]

T1 is in stock again. :sunglasses:

[Aleister]

Hey freeme, is there a new coupon for this? The old one doesn’t work anymore for me (I’ve already ordered one T1 using the old coupon code)

[delete]

wait for a new codes.thank you

[maukka]

I would’ve gotten another one as well, but the $5 shipping and the coupon not working kills it for me.

[freeme (youtube.com/@1thedeals)]

Seem like T1 has stocked up.

[Nicolicous]

code?

[freeme (youtube.com/@1thedeals)]

I requested for another 100pcs today. Hope it gets approved from their boss.

@Nicolicous

code?

[Coscar]

@freeme

Seem like T1 has stocked up.

Please send new code if they become available
Thanks Freeme

[Lux-Perpetua]

I already showed my interest before but since I changed my user name I want to be double-safe to get on the list for the next batch Thanks for your efforts Freeme!
