The Samsung 21700 40T battery is built for strength and endurance, and is a solid choice to pair with the Pico 21700 box mod. Independent testing rated this battery at 4000mAh and 25A, and it’s our go to battery for power hungry users. This battery is not compatible with box mods that only accept 18650 batteries.

Your samsung battery may be labeled with the following message:

Warning! Fire Hazard. Never Carry In Pocket. Not for E-Cig or Vape.

This warning was in response to problems with use in unregulated box mods, a product not available at Planet of the Vapes. This battery has, and will continue to perform well with the products we sell, despite the label. If you have any questions or concerns, do not hesitate to reach out to us at

Best batteries for Mech use.

These are the very best batteries that I found to run single or in series. Single I find they run between 70 and 85 Watts... somewhere around there. They hit hard and last me most of the day. Absolutely love these bangers and imo they are definitely worth getting for any 21700 mech usera. Also using one in my V Pulse AIO at the moment. I've been running it for 9 hours so far today and I'm down to two bars just to give you an idea in a regulated at 35W.
