I
would be wary of spending money on used batteries. Without the knowledge and
equipment to test them, it can be a real crapshoot. If they offer them to you
for free, that would be a slightly different story. But either way, if you are
off grid, batteries are the backbone of your system. Take them seriously and
treat them well. If you need to skimp, skimp on production. It is easier to
expand production than battery banks.
