The LEAF charges them up to 4.10V on a "100%" charge. You might see 4.12V maximum on a few cells, especially on the 2013+ LEAFs compared to the 2011-2012 LEAFs which seem to charge to a slightly lower voltage. The LEAF BMS will report this charge to be 95-96% or so. An 80% charge will charge the cells to around 4.02V. 50% charge is around 3.90V. You get the first low battery warning around 3.75V and the second warning around 3.68V. The car opens up the contactors around 3.30V, but you can probably take it down to 3.0V or so if you do it very gently. Some others have mentioned charging up to 4.2V, but I think that's too high since Nissan doesn't get close to that. -Dave _______________________________________________ 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)
