Maximum charge voltage is 4.25 volts. Please check your cells with a volt meter during initial charging to be sure that your charger cuts off below this level, or cycle life will be reduced

    • High current rated
    • Lowest permitted discharge voltage - 2.5 V
    • Cycle life - 500 cycles
    • Max charging rate - 4.5 Amps

    Vamo V5 required replacement
      As stated, it quit working after about 20 days. Contacted Smoktek and it was replaced without a problem. Now I will update on it when I've used it a while. Smoktek really does have great CS and will buy from them again.

    VAMO 5 & Efest 18350 batts.
      Always getting questions: What make is that?, What is the cost?, Where did you get it? How long do the batts. Last? They all say they like the looks of it. I refer them to your web-site for all the answers. That's the best & cheapest advertisement you ca have. Good products at reasonable price. Excellent customer service. Keep up the good work.

    Used in Z-Max Mini
      Gets the job done. One lasts 4 hours with heavy use at 8.5 watts. Had to remove the battery's decals for it to fit in the z-max mini.

      These work really good in the VAMO. They go for from 3-5 hours, depending on my volts/watts setting. Recharge is pretty fast too.

      These have been about the same for charge time in my Mod as the AW IMR's. I have no complaints. Lasts about 1 day in my v8 vv Mod. Good product.
