Willie, How about some NIMH battery modules from the Toyota Prius or other hybrid vehicle? They are 7.2 Volts and 6.5 Ah. Two battery modules in parallel would be 13 Ah and 5 of those in series would be 36 Volts. However, I think NiMH do not like running in parallel. This is ten modules total, at $45 each used is $450 before a charger, monitor, BMS, contacts, etc.... Maybe two series strings could be used without parallel bridges at each battery, only connect them with contactors when driving the bike. More cost effective would be going with 5 modules in series at 6.5 Ah and 36 Volts. Less range but less $$ and simpler.
Have you looked at Leaf Lithium modules?

The OEM replacement is nearly $500. Can someone point me toward a better solution? 36v, ~10ah. Has anyone heard of anyone doing cell replacements? _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
