If you use small battery and R1 have low value this can cause voltage drop. For example full car battery have voltage 12,72V-12,73V when cranking (apply load) voltage fall down to around 10-10,5V.

Yes, that is possible but we must do some tricks. I use small 1,5V battery to power red LEDs in my fishing lures. **broken link removed** https://www.google.rs/search?q=Joul...urce=og&sa=N&tab=wi&ei=Qhs_UoeRDMPetAbZ4YCwDg Best regards, Peter
