<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Higher than 4 strings in parallel is not recommended as the risk of unbalanced charge between the strings will possibly increase over time and endanger the
life of the units. Fewer strings in parallel is often preferred for price $ per Ah, fewer interconnects, sometimes optimum foot print, with the exception of unit weight challenges in few cases. Various lifting tools exists or created by Wrenches fellows for
proper positing heavy units<o:p></o:p></span></p>

<p class="MsoNormal">Client has asked me to compare the cycle life because he is upgrading a large battery bank and has been convinced by a Xantrex "scientist" that golf cart batteries are superior to L-16's even though it involves twice as many batteries,
connections, cells, footprint etc. So to convince his purchasing committee he wants to know the difference in cycle life between a U.S.B 208 and a Surrette S-460.<o:p></o:p></p>

made US Battery. <a href="http://starlightsolar.com/interstate.htm">http://starlightsolar.com/interstate.htm</a>) I consider Rolls a superior long life battery compared to any other L16's.<o:p></o:p></p>

<p class="MsoNormal">Hi Wrenches, trying to compare battery cycle life on L-16 Surrette/Rolls vs. U.S. Battery golf cart. Can't seem to find any clear info on the U.S. Battery 208 a/h golf cart. The chart that U.S. battery shows on their website only gives
one cycle life graph for all of their batteries whereas Surrette/Rolls differentiates between the series 4000 and series 5000.<o:p></o:p></p>
