Do you know which CALB's these were. The Blue or the Gray ? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Cruisin Sent: Tuesday, January 28, 2014 4:29 PM To: [email protected] Subject: Re: [EVDL] Cold Charging Lithium Experiences
If the cold isn't enough to worry when using the CALB 180ah cells, early failure is substantial with the CALB cells. I have 6 customers using 180's and all have had failures of at least one cell in the first two years. All use a BMS and a programmed Elcon, so I know the systems are designed right. About half died while driving, BMS alerted and they shut it down. The others started change in resistance values making it difficult to get a complete charge, or early discharge alarm from the BMS. One died 1 day after a one year warranty. No replacement even though CALB was told of a possible problem early on. I don't want to alarm anybody, and I am sure some forum junkie will jump in a say he has been using the cells forever without a problem. Probably some have, but my experience is that most will have a early failure. Recommendation, carry sufficient tools and HV and BMS cables to be able to isolate the cell should experience this problem. Otherwise, you will be stuck somewhere where you don't want to be. Been there and done. By the way, don't expect CALB to do anything, even during a so called warranty period. Support and service ended when you put them in your donor. I hope I didn't hijack this thread, just wanted to pass on what I think is a troublesome problem. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Cold-Charging-Lithium-Experiences-tp4667675p4667691.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ 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)
