[Ham-Computers] Parallel gelcel batteries

[Loren Moline WA7SKT]

Goran,

I see no reason why it wouldnt work. Each battery will draw a current 
dependent on its charge condition with the total for all the batteries being 
drawn from the charger of course.

There are 2 reasons I see for diodes which will drop voltage by .7 volts. 
One is to prevent discharge through a charging device and the other to 
prevent drawing from certain batteries while being able to charge all from 
same source. A light bulb of proper wattage can be a good current limiter 
with the current max being the load of the light bulb at 12 volts.
