I feel stupid for asking... because I have been playing with my own linear designs and I can't find any information through searching here...
using an LM350 (or LM317) I can't get a solid 1500+ mA with 2 18650s, but I can with 3.
1. Is this just because the output capabilities of these batteries may not be high enough? Other higher output 18650s could do the job?
2. If I use 3 18650s (12v in) but have current set to 1500mA, is the voltage going to be too high for a 445? The reason I ask is because I know these have variable voltage when in regulate current mode... so will the voltage matter?
I guess I am really wondering this in general for this. does volts in matter when regulating current?
I know I've seen this posted somewhere.. I just can't find it again.. Sorry for making a new thread!
