Slightly OT but given the group's experience with batteries figured I would ask here.
About two and a half years ago I replaced my original flooded lead acid battery pack (US2200XC) with lithium cells and re-tasked my flooded lead acid batteries to solar backup for my house. Now almost five years out four of the twenty four original batteries in the house backup have failed. I reconfigured the pack and can live with the reduced capacity for a while. But I would like to add the capacity back. Options: 1. Replace the four bad batteries with four new batteries of the same type and rated capacity as the original. 2. Replace the four bad batteries with four new batteries of capacity roughly 60% of the original (trying to match what I think the current capacity of the original batteries). 3. Spend $2-$5K on a new pack. Thoughts? Thanks in advance, Barry Oppenheim _______________________________________________ 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)
