    How much do batteries matter? $$$ vs cheap

    TBH... I want the capacity I expect, and now with higher demand lights, I want the Amps.... Then there is safety concerns... I have hundreds of dollars of light, why play around on batteries

    Let's talk chargers...

    sideline....Is there a master charger thread? I have just the basic xtar wp6... looking for a good basic 4 bay for brother in law.. Also, what is the largest bay charger now? 8..10? I think the 8 bay ones charge at a low rate. I have run out of room on my wp6.. Maybe just another wp6 or something?

    Test/Review of Analyzing Charger LiitoKala Engineer Lii-260

    SO after reading this test, from two years ago.. I notice the length limitation... Is this how the charger is made today? Heck, since I use keeppowers and now a dozen panasonics, I am unsure what my battery lengths are.... Tony

    KP3100 (4) not taking a charge...

    Age, I cant tell. Ive gotten a few orders, cant tell them apart. I tried to check the voltage....it seemed like it was 4.1 volts right away for any cell I tested..Two of the four seem to be charging normally so I am going to see how they perform at work. I might buy an IMR cell for the Sinner...

    KP3100 (4) not taking a charge...

    Well no, not really that hot. Some rooms yes, but overall normal mechanical rooms.. Age, hard to tell, the batteries are not marked when I got them. I was wondering if maybe the high power Sinner light had something to do with it.. Like they can't handle the load

    KP3100 (4) not taking a charge...

    So I have a lot of these cells around, and the ones at work have gone ..bad? They read around 3.4 volts....and when placed in either Xtar wp6 charger, they go red right away, then green in 2-3 seconds... I tried to 'manually' charge then with a Hyperion charger...a couple took some charging a...

    zebralights and IMR's.....

    I can already see problems...they show voltages from 3.6-4.0, yet most wont run the sc600 on high for more than 30 seconds. Furthermore I am using an Xtar charger and they charge up Quickly...Too quickly. Some wont even turn the charger red even though the read 3.8V I am not sure I can use any...

    zebralights and IMR's.....

    Found this on their site : Builtin over-discharging protection with 2.7V cutoff So this means I can use an 18650 IMR cell I scavenged from some milwaukee packs at work...?? I got about 20 3-cell packs....I figure SOME of the cells have to be good...I took one apart and two cells took a...
