Power supply diode voltage question

Vk2NU
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

A 1N5400 series would be OK for a barefoot K2. A 1N4000 series isn't big
enough.
If you just need to reduce voltage why not open up the power supply and
look for a voltage setting pot?
