If you assume that you are going to need, say, 20 kWhs/day every day from your battery bank, what would be the cost to do so using these three options? (If anyone is interested in the Sony spec sheet, let me know off-list.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>For the lead-acid, you would actually need 40 kWhs worth of storage to get 20 kWhs/day since those batteries are typically rated at only 50 percent DOD. Whereas using either the Aquion ion hybrid or Sony Li-Fe-Po you would only need 20 kWhs worth since both are rated at 100 percent DOD. (The Sony battery is rated at 5,000 cycles DOD.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The numbers I’ve come up with:<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>Lead-acid with 40 kWhs = $6,000<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>Aquion with 22 kWhs = $12,00<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span style='font-family:Symbol'><span style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]>Sony with 20 kWhs = $24,000<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Conclusion of story, given today’s prices: pay less upfront to get a good, ole fashioned Trojan L16HC (or equivalent) and replace ‘em in five years or so or pay a lot more upfront and have a battery that will last a helluva lot longer.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>marco<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> RE-wrenches [<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">mailto:re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Kirpal Khalsa<br><b>Sent:</b> Sunday, February 15, 2015 4:56 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Aquian Energy Batteries.<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Hi Wrenches!!
