Hi Robert,
Yes, I've run TS-7800 from several different 12 V sealed lead-acid batteries
(from 7 Ah to 70+ Ah). With option TS-781 of course, the small 8...30V to 5V
converter. Then you don't have to add anything to monitor battery voltage
(TS-781 input voltage it is directly attached to one of the ADCs with 1/9
voltage divider).
But no experience with a solar panel. Should be easy to make a simple charging
system which does not need the controlling opportunities of TS-7800. With a
lead-acid battery and a solar panel mixed system, the only thing you should
need (for a 12 volt battery) is a small system with 13.6...13.8 volt voltage
limit for float charging.
It should be equally easy to use a 6 volt lead-acid battery with the 5 volt
power system (that means, if you don't have the TS-781). You certainly need to
add 2...3 silicon diodes in series (type 1N4007 for example) between battery
(+) and TS-7800 (+), or else, something on the TS-7800 may burn. To charge the
battery with float charging, you need a voltage limit of 6.8...6.9 volts. For
full (cyclic) charging, the 2...3 silicon diodes are not good enough for
protection, because the voltage of a 3-cell sealed lead-acid battery may go up
to 7.5 volts (sometimes more), and then you need a good 5 volt voltage
converter with a low drop, in the place of the diodes.
I've also used four NiMH AA-size batteries in series (about 4.8 volts) to power
the TS-7800, but it was a temporary solution because the batteries won't
probably last over an hour (the current consumption is up to 1 amp).
I haven't tried lithium (Li-ion, LiPo) based technologies.
