hi im looking for 10440 3.6 volt batteries if any one has any, i got my br diodes and i need some batteries and i dont want to order any from dx, just because how long it takes to get here, but if any one has any let me no or another place i can get buy thim thanks

dude just get them from DX. by the time you find someone and get them you'll could have your order recieved from DX.

Have you try using just two? 2 will give you over 7.2v that should be enought for Blu-Ray running only at 40mA.

ok the pic i posted if i put 2 batteries in it besides three would that work to power the blu-ray

you can put a dummy cell in the empty slot or solder a wire to bridge the connection (+ ----- -)

Nope, you need at least 8v to run a bluray as you need at least 6 to run a red, of course that's assuming he's going to use DDL's driver.

according to the datasheet the VDrop is 1.6v running at 20~200mA at +50c. 7.2v-1.6v=5.6v, Blu-Ray running at 40mA only needs 4.5v.

Configured as a current regulator, you have the reference voltage (1.25V) to contend with also.. The total forward drop will be about 2.9V. So it's more like 7.2V-1.6V-1.25V=4.35V.

Bluray LDs need between 4.5 to 5v, even if the one jake's using needs 4.5v the LM317 still takes another 3v so you would need a minimum of 7.5v to power it.

yea im useing ddl driver

my bad, looks like 2x 3.6v might not work after all. :-[ Left out 1.25v voltage refrence. :-[
chido was right.
