Rexlion:
The Tenavolts kit came today (Prime delivery van, how slick is that?). One of the 4 cells tested 0 volts out of the box. :rage: The others tested 1.54-1.55V. I thought, this one cell is probably toast, and if so I’m sending the whole thing back. But after charging fully (blue light turns off when done) I set the cell up in an old ITP C7 on high, and it’s been putting out good light for nearly an hour now, so I guess it’s going to be ok.
There is a protection circuit inside. If it trips, it cuts off voltage. Putting it back on the charger resets it, I believe.
What’s interesting, though, is the way these cells act in a light that has step-down regulation. I put one in a Zebralight SC5W and it only put out about 200 or so lumens instead of the possible 500… and within 30 seconds it had stepped down to maybe 5-10 lumens. The flashlight didn’t know what to make of it. Not enough current, I guess.
These cells were not designed to deliver lots of current - going above 1.5A will cause the internal buck converter to overheat and shut down.

This coupon seems to work for both models of this “work light”. The rechargeable USB one I was able to get out the door for 6.XX tax included. The AA version is even cheaper. I’ve found these type of work lights are pretty helpful when puttering around in the basement or when the lights go out.
Passing along in case someone else finds it helpful.

Lightbringer:
Reverse-charging is when one gives up the ghost, and the other cells happily keep pushing current the wrong way through it.
Output cap, blocking diode, anything on the output of the buck regulator might end up frying unless the mfr took steps to keep that from happening.
I hear ya. Product description states: “Integrated 3-in-1 safety chip: Extra charge, discharge and short circuit protection, no over-charge, damage to lithium core or extreme temperature,” but how that works in practice is anyone’s guess.

What do you guys think is the source of power in this rechargeable one? Two 18650 cells? Three 18650 cells? Something else?

If the ad is to be believed, its 6000mah. Its likely a pouch pack. if we are lucky its 2x18650. Given the thickness, I’m inclined to think its a pouch.

You can PM me if you prefer. I could really use one of these, thanks.

You have to use the vipon code at amazon and put it in the promotional code box at checkout to get the discount.
Unfortunately the code want be available again for about 13 hours.
Thanks for the tear down and shot of the pill. the shelf looks like it wasn’t a solid piece but tacked on afterwards.

I stand corrected. The light has a 3x18650 wrapped pack in it. It is indeed 6000mah 3.7v.

You opened yours up?
I’m going to run a discharge capacity test when I get mine.
Wait… what?
The vipon code for the moobibear(!) is 11.27, but it’s listed on amazon at 10.99, straight-up.
What’m I missing, and how youse get ’em for 5-6bux?

vipon code brings it down to 20, 5% coupon knocks it down a bit more. Got mine for <20bux out the door.
Ah, here we are…

Ignore the displayed pricing and apply Vipon code anyway.

Of course I opened it. It had screws. Isnt that what you are supposed to do with something you just purchase? Open it up and see whats inside/how it works? Thats how I grew up at least.
Ran out for the day, so I gots ta wait.
