Choose from 14500 900mah protected, 14500 600mah High Drain, 10440 350mah High Drain, and 10440 600mah protected cells. The high drain cells probalby have a truer mah rating. I have been using the 10440 high drains on the LS and they seem to work better than the 10440 protected. Spacers are needed with the 14500 HD batteries. They are included when you order the batteries. All lithium Ion batteries sold on this site are protected. If you are using Lithium Ion batteries in any mod, always buy the protected version.
