    Simply don't bother buying 18650 batteries from anywhere else. They'll over state their Mah by miles. These batteries, however, are in a different league. I tested their capacity, and they're spot on. They'll outrun the cheap copies by a factor of 4!


    these the ones for heavy wattage 60w + cope np and last. The bigger capacity mah ones kill easily so don't last. Recommend these


    Genuine Samsung 25r batteries. Very very pleased. My last order of the Samsung 25r batteries, from a different company were fake batteries. And the difference between authentic and fake batteries is an unbelievable difference. You can trust 100%.

    Genuine Samsung 25r batteries, absolutely great customer service too, even when the delivery service encountered problems probably due to current circumstances the customer service guys shipped out another set for me via royal mail and I received them the following day. Great value and super quick replies from customer service. I will definitely continue to buy from here in future.
