At the Level of 3000 mAh / 20A there are only 3 manufacturer (OEM´s): 1. LG HG2 2. Samsung INR18650-30Q 3. Sony VTC6 In some countries you are legaly not allowed to sell industrial batteries, because they are missing important Information for normal consumers. Brands like AW, Torchy and others...

I am not electric-Ing., but as far as I know Li-Ion charging method is CC-CV. The TC that Xtar mention is relevant, when a battery is slightly deep discharged. The charger detect the voltage in the battery and Charge with lower current, till the battery reaches a certain Level of Voltage. Almost...

I would not recomend any Charger that has an internal transformator and is not using a Power supply. The most problematic part in a charger in terms of safety is the part in which 110V are reduced to 12V, or 5V (in Europe 220V).

Most of the old Budget chargers (Ultrafire, Surfire etc.) had a cut-off at 4,13V - 4,15V, because they had no Controller. In battery-packs the cut-off will be terminated by a PCB (Protection-Circuit-Board), or by BMS (Battery Management System). On a regulated Mode the voltage in the mode is...

We say in German: just a stupid cow seeks his butcher himself

One battery (the purple one) seems to have asthma occurring at 15A :danger: Thanks Mooch - you help us to unmask Those charlatans

Thanks Mooch. I think Xtar should concetrate on what they can do the best - Chargers

I agree with Mooch and wanted to add just one small issue. If you Charge a battery with low current (up to 0,5C), you can use it directly after it has finished to Charge. Using high current (above 1C) will require a certain break (battery have to cool down). Mooch mentioned that high charging...

I think it would be very helpful, if we recommend at least 2-3 batteries and notonly 1. Sometime a certain battery is out-of-Stock, sometime is really expensive, because the availability at a certain time is low. I would add to the list the following batteries: 1. Samsung INR18650-30Q (pink...

Hi Batitude, I would need some few days to give you a good answer, but regarding 18650...most probably you would be able to recognize the manufacturer according to its Plus-side. LG, Panasonic, Sanyo, Sony and SDI are using very often the same ventilation system in their batteries. Sony has f.e...

Well it is enough to read: "after more than 1000 cycles, the power still remain 80%" :-x Those Marketing methodes belong to the past...or maybe we talk about eneloop Li-Ion? :banana:

Some Information to AW and I hope I make myself no enemy. AW was a pioneer in offering Li-Ion batteries (mainly 18650) for LEd Flashlights with PCB (Protection Circuit Board). AW used to purchase the Li-Ion cells from Panasonic (mainly) and let them being assembled in China. At a Point, in which...

Hi Ken, Thanks for your informative answer. I am using a VTC Mini at 15W maximum, therefore I was wondering if those boxes with 200 Watt, or even 250 Watt really are in a position to deliver?

I have a question, that maybe sounds stupid, but I´ll try it and hope to get a serious answer - how do you really know, that if a manufacturer writes 250 Watt, the Box can really reach this energy? I have an old test from Germany in mind, where all tested boxes were around 10% - 15% away from...

First In my comment you didn´t read any single Evaluation to AW batteries. AW was one of the first Brands for Li-Ion batteries - that is something you can´t take from them. But in the meanwhile there are few other good Brands like Keepower, EVVA and Orbtronics on the market and it is not like...
