    Great Batteries

    These batteries are well worth the money, especially if you are going to be using them in a Mech Mod. A Brick and Mortar shop will charge you around $13.99 each, so a great buy for $11.69 per pair if you get a Public Servant Discount.

    Fantastic Batteries

    The price for the pair is more than reasonable. Honestly it's very reassuring knowing that you get get batteries from a reputable vendor and not have to worry if they have been used or re-wrapped. Samsung 25R's are some of the best you can get right now. I put mine threw hell and they never get hot. I highly recommend them.

    Strong product.

    I have a married pair in my CCI box I have been running builds around .09-.15 and these batteries have no problem taking the heat. And have a long lasting charge. Good strong product. Have two others I use in my Apollo and well lets just say it can take a good sub ohm mech build. Lol. Will continue to purchase.
