Re: What type of 18650 do you use with the Flexdri
Yep, all 15650's are rechargeable... All of them will be able to deliver the amount of current required by the flexdrive... The only difference is how long it will last per charge. You've missed the H on the end of "mAh".. which stands for "hours", as in "milliamp-hours". As in, how many milliamps it will be able to deliver for an hour, per charge... if your flexdrive is getting some 90% efficiency, and your laser is drawing 300mA, it's drawing 330mA from the battery... a 3300mAh battery (for example) would last ten hours at that draw (theoretically).
