Power supply plus deep cycle battery, blocking diode, etc.
 

Hi all...
I am currently using a homebrew 35 amp power supply that has a 50 amp
blocking diode in series with the B+ line going to a lead acid deep cycle
battery to feed two hf rigs and one vhf/uhf rig.

The power supply has no real current limiting and I want to insert a bit of
resistance in the B+ line to keep the current from exceeding 8 amps or so on
battery charge up. Can anyone give me an idea of what value would be
appropriate.

I am also thinking of replacing the deep cycle battery with a sealed
battery...one of those that is advertised to never need fluids, won't leak,
etc....are these appropriate for this application?

Thanks in advance....de Denton WB7TDG
