26650 Batteries

I can confirm that as well, I got them from Cyberport888 with my M10 and they appear to have protection. I haven't tested it though.

Just got a reply from Manafont, the double trustfire charger is 1 amp per bay..

wow, I wasn't expecting an answer like that. Excellent! I think I may put an order in for one for when I need two batteries ready at the same time.

Benckie, nice find as usual

It doesn't mention 14500... is it bad to charge 14500 with this charger?

taz, I think it's best to charge a 14500 at .5amp or lower. 1amp will reduce battery life.

I got the same reply earlier today, it would be a good buy to me if you needed a 26650 charger a big bonus would be it does not have a fixed power cord like some or an external power supply with a foreign country wall plug and maybe (looks like) if it takes cigarette lighter cord with a small male plug of the end as i have heaps of spares of both.

But i use my iCharger 106B+ with 240 volt and 12 volt plus for charging/discharging all my batteries, i plan to gift the charger i reviewed after a few more uses to make sure its OK to give to some body.

Just a heads up, my 4Sevens charger also charges the KingKong ICR26650E to 4.2v, just like the 4Seven brand cells.

Wouldn’t have seen any reason it would do that, lol.

True, but 4Sevens has a disclaimer on the site stating their charger is only designed to charge their 26650's correctly. That's the only reason I mention it.

Ah, ok. Willing to bet it’s to boost sales of their own 26650 batteries more than it is anything else.

Most company's say that like from laptop to car manufactures i take it with a pinch of salt

I love me some Lighthound! Some of the best guys in the biz with great prices and unsurpassed punctuality and customer service, and my #1 go to company for sure. But I've had lots of trouble with the 3.5aH 26650 IMRs they sell. Maybe it's a bad batch, or maybe the cells are fine and I'm just doing something wrong, but 3 of the last 5 I bought from them leaked. 1 leaked on the initial charge (other 2 didn't), then 1 leaked for no apparent reason after the second charge, and 1 leaking in transport before it even got to my house. Very strange.

Interesting indeed. I would expect higher / better from lighthound. Leaking/venting in transit does not sound good.

Curious, what charger are you using? Is it terminating at ~4.2V (as checked on a meter?)

It was a cheap Tenergy Li-ion/LiPo charger, that's why I say maybe it was my fault. Terminates at 4.2 +/- 1.5% with 1 cell though (see link below)

I got it specifically to charge these 26650s because I didn't have any other charger that I felt comfortable using to charge them, and have had good experiences with Tenergy's NiMH 'smart' chargers. I charged the cells 1 at a time, 2 did just fine and 2 didn't.

Did you send them back? The one leaking in transit tells me you got a bad lot?

Yeah, I sent them back. They made good and sent me 2 new ones. The last replacement they sent leaked too though, so I didn't even hit 'em up for another. I hate being a pain in the arse, especially since they've always been such an excellent company. Very fast delivery, great products, easy RMAs with no questions asked, and good prices. I've placed several more orders with them since then because I guess it was just a fluke, but I'll stay away from their 26650s after that.

I think you should still return them for an RMA. They are a GOOD upstanding company, you'd be doing them a favor by letting them know the problem appears to be more wide-spread than a couple isolated incidences. All it takes is ONE flame/vent/fire incident (property damage, personal injury...etc) to bring down the entire reputation of the retailer. I believe LH understands this and they would not see you as a "pain" at all... so long as you are professional and polite. See it s a chance to partner and collaborate with them. Good luck though in whatever you do!!

Kramer, you make a good point. I will take your advice and inform them of my concerns.

Let us know what happens.

Anyone else have these cells or have a similar experience with leaking? I too think Lighthound is a great vendor and I don't want to put a warning in the OP unless warranted.

OK, talked with LH. They are conducting an investigation with the cells I returned to them, but stated that my case was the only issue with this batch of cells so far, so at this point they're considering it a fluke. They also said they'd send me another replacement after a discharge/charge cycle had been performed to verify it was a good cell prior to shipment.

The professionalism of LH is truly top notch. Couldn't ask for more. :)
