[Elecraft] Power supply diode voltage question

[vk2nu at bigpond.net.au]

Hi all,

Apologies for my lack of electrical knowledge, but I have a question regarding power supplies for the battery option I'm installing in the K2.

I have a 15v/6A supply I'm planning to use to charge the battery and power the K2 from. I'd planned to install a diode in series with the+ve of the PSU, and just wanted to check which diode I should use ? I have a supply of 1n4004's which I think will give me the required voltage drop, but just want to check that these are OK (I note they are rated at 1A, and think I might need something bigger ?).

If no good, can anyone recommend which ones I should be using.

Cheers

David, VK2NU
