Jay: There are several lithium chemistries out there. The exact voltages will depend on the chemistry but in general Lithium is around 3 V/cell. I am liking LiFePO4 (China Aviation Lithium Battery - CALB) these days and they need:
Vnom = 3.2 V/Cell Vcharge_max = 3.6 V/Cell (but this will require active battery management on a per cell basis). Vcharge_max_good_idea = 3.5 V/Cell Lithium is sensitive to overcharge and very bad things can happen if they are overcharged. Active battery management and cell balancing is likely needed if they are to be stable over the long term.

I'm curious if our current range of inverters can work with these batteries, at least on the load side, probably not on the charging side. thanks, jay peltz power _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org CONFIDENTIALITY NOTICE: This e-mail and its attachments are intended only for the use of the individual or entity who is the intended recipient and may contain information that is privileged, confidential and exempt from disclosure or any type of use under applicable law.
