    Unfortunately, the TR 001 would continue to trickle charge batteries as long as they were left in the charger with the green light turned on. Leaving the batteries in the charger for several hours after the green light went on resulted in batteries overcharged to 4.3V.
    You nailed it yzer that explains it I charge my battery over night & leave it in the charger till I wake up in the morning I wont do that any more thanks for the explanation!

    4.3V is too much charge on the battery. Before going further I would measure the battery voltage with a DMM as well as the voltmeter in the Sigelei to see if they agree. I can't do without a DMM for vaping. I test every carto coil before I fill a carto for the first time.

    I posted before that I had problems with a two year-old Trustfire TR 001. When new it would bring batteries to 4.17V or so at the time the red light turned off and the green light turned on. Unfortunately, the TR 001 would continue to trickle charge batteries as long as they were left in the charger with the green light turned on. Leaving the batteries in the charger for several hours after the green light went on resulted in batteries overcharged to 4.3V.

    You can put the overcharged battery into the Sigelei and see if the overvoltage protection will allow you to use it. If it does then use the battery but keep alert for signs of battery overheating and potential failure.

    4.3V probably won't kill the battery but it will shorten the battery lifespan if done frequently.

    I recommend the four bay Nitecore Intellicharger i-4. It isn't perfect. The sliding battery contacts are a bit balky. However, it does a decent job at charging and stops charging completely after batteries hit 4.2V. I bought one from Amazon for $17 several weeks ago.

    I really wish all chargers had a voltage readout of current state. It would save a lot of problems. That is the only feature I wish the Nitecore had.

    Two points:
    1. Overcharging batteries is a sure-fire way to reduce their lifespan: Charging Lithium-Ion Batteries

    2. I note many have recommended lubricating the screw threads in the Sigelei ZMax telescope section. Noalox is one suitable lubricant since it is conductive. Yet, many have also complained about misfires. May I suggest a better (and cheaper) alternative?
    Go down to your local arts and crafts store and buy a 4B (very soft) pencil. The lead in this is good quality graphite which is both highly conductive and an excellent lubricant. Clean and degrease the threaded sections thoroughly with something like alcohol, then let dry. Scribble a generous dirty black mess onto the inner threads of the telescope section from 5mm down (so handling the device doesn't give you dirty fingers) and the screw threads in the battery end-cap. Reassemble the device to grind the graphite into the threads. Give it a quick clean with a damp cloth to remove any excess graphite that may have escaped onto the outer body and you'll probably never misfire again. The only thing to watch out for is to avoid touching the ground-in graphite on the screw threads in future when changing batteries (you'll get dirty fingers!). Safe, non-toxic, long-lasting and effective.

    All the best,

    Many years ago my father who was a locksmith used a dry white graphite to lubricate locks. No mess or staining with the white color. I wonder if it is still around and if so how costly?

    Going over my budget I found out that I could spare some cash & ordered the following:
    Nitecore i4 Pro Intelligent Universal Charger
    Efest 18650 30A 2100mAh Battery
    Panasonic IMR Hybrid High Drain 18650 2250mah
    Efest IMR18500 Chemically Safe Li-ion 3.7V 1100mAh
    Should receive them by Monday that will give me a safe charger & 3 extra batteries besides the only Samsung that I have for now.

    My first V3 came with one battery cap. That is the tall cap (15mm). My second V3 came with two battery caps. It has the tall cap and the short cap (10mm).

    With the short cap the V3 will measure only 100mm in length with 18350. With the tall cap it's 105mm with 18350.

    I use the short cap only with 18350. The tall cap is easier to handle and to thread to the tube so I use it for all of the battery sizes larger than 18350. With the longer batteries the overall Sigelei length is the same with both caps so long as the battery spring is 1/2 compressed.

    First of all make certain you get a removable top ring. Makes CE4 atomizers a lot easier. I think the V5 Vamo does that as well. The SVD is superior in features many have had problems including me. I would also consider the Sigelei Zmax. Either V3 or V5. Both have removable top rings. The V5 has cell phone charging. I have used all three. Prefer the Zmax. The Vamos are a good choice since they are so tough. If you can try to find a store and see what looks and feels better to you. Also try the menu system if you can as well.

    Guys how would you compare it to the VAMO and the SVD? I am considering buying one of these and I can't decide! I am talking only about the V3 (flat head).

    Zmax blows them away in form, function, and durability. Vamo = stripped 510 .. Svd = wonky buttons, giant night stick
    Zmax = solid stainless steel all the way through

    I too am a big fan of the Zmax. However I have had a Vamo V2 for over a year now and it still works fine. The deciding issue now is both are about in the same price range. That being said I too would select the Zmax for certain over the Vamos.

    I have two ZMax V3's and a Vamo V3 and prefer the ZMax V3's. The Vamo is a lighter construction and doesn't feel as "solid" as the ZMax in my hand. I'm less worried about the Zmax if I drop it. At first, I liked the two extra buttons to easily adjust the voltage/power on the Vamo, but then I found that they were getting pressed by accident and changing my power level. I now much prefer the single button interface even if it takes slightly longer along with a few extra clicks to get to the menu.
