top rate battery power

These Ultra fire 3.7v batteries are excellent for powering the led torches. They extend the length of time they last way beyond the option of having 3 aaa batteries.

18650 rechargeable batteries

Using these batteries with a solar water pump. In use for a while now and so far very good. I didn't expect much from batteries so cheap but they are far exceeding my expectations. Recommended.
