Re: [EVDL] DC/DC converter at Electronic Goldmine - solar

Re: [EVDL] DC/DC converter at Electronic Goldmine

I checked out the info video on the Iota and they can be attached in series or parallel. And the ‘smart module’ does make it a 4 stage charger and is only $20. Worth trying out. Of course I found a few other goodies I ‘needed’ on the Goldmine site -Steve > On Feb 12, 2021, at 7:37 PM,

Re: [EVDL] DC/DC converter at Electronic Goldmine

This is quantity ONE! If you put "2" in the quantity field, the per-unit price goes up to $500! So they REALLY mean "ONE ONLY!" I have six of them that I bought during prior sales. I was hoping to have twelve of them, to charge my 144V string of NiCds. All six look essentially unused. I
