The website mentioned this laser uses a Li-Ion 18650 battery. You can buy some here for dirt cheap: All-Battery.com: Tenergy Li-Ion 18650 Cylindrical 3.7V 2600mAh Flat Top Rechargeable Battery

Default Re: Which Battery Should I Buy for This

Everybody buy panasonic ones and ive got 2 more question.
What is mAh means? More mAh means more power? I want a battery that works with my laser with max performance and dont harm my laser.

And ive got a question about duty cycle. For example this laser have 45 sec on, 30 sec off. Can i use it 3 on 2 off ?

Thanks alot.

I don't know what mAh means, so can't help you on that. But the duty cycle means how long you can keep your laser on. If you keep it on for a full 45 seconds, you need to let it rest for 30 seconds. If by 3 on/2 off you mean 30 seconds on, and 20 seconds off, then yes, you can do that

Capacity is what is quantified by the mah rating.

If a cell has a mah rating of 1000 . . .

then it can deliver 1000 milliamps (1 amp) for 1 full hour.

(1000ma) x (1 hour) = 1000 mah capacity.

Duty cycle of a laser diode is usually determined by

the total amount of metal heatsink attached to the laser diode.

This picture shows a 100% duty cycle 5/8" thick aluminum heatsink for a 405nm laser I built:



This is the thread for the C8 build:
