Just wondering if i can use any charger for Li-ion batteries to charge my LiFePO4 batteries, as long as voltage is the same :confused:
Unfortunately my cheep Ultrafire WF-188 from Deal Extreme has difficulties charging almost all my batteries, including any CR123 both Li-ion and LiFePO4.
Hi I am all new to lasers. I would like to buy a laser
where the beam can be seen on long distances (kilometers)
I am not interested in burning stuff.
I am a little confused with all the options??
Which one would you recommend of these two from O Like?
400mW green laser torch...
