Re: [EVGRAY] charging a coil like a cap

Body

The 3055 can't take back spikes very well .you guy try the no acid battery
yet .they use Epson salts and dump out the acid and rinse out the battery
and then use something else ?I think bicarb ? I'll go look it up but the
point is you can get big dead batteries and convert to this type .it's a
little lower voltage but you can run them dead with no harm .should last
for ever no acid is no sulfate crystals busting up your plates and no
destroyed shirts .just a little less voltage but all amps . I have several
I'm going to try some fail but if you get a good one its good for life . I
like the no fracking acid part .
