Hi Cruisin and All, Until now I've stuck with lead because the problems you mentioned and more importantly the cost of new cells.
Now I know totaled Leaf's are around means I'm finally going Lithium mostly because they cost less. Do you or anyone have pics of how to make smaller packs of them, hints, etc I can check out? I chased the ones I mentioned before down selling a mile away from me but it turned out to be a third party advertising old items /wrecked cars in this case trying to conned you into buying crash reports on them. But they had already sold in real life. For me a Leaf's battery pack will give my lightweight EV's 250-350 miles of range likely powering 3 of them. If I want to all in with the Lumberghini and it is designed to hold 720lbs of lead so it can, put them all in it would 250 mile range or so though 100 miles worth and a DC generator is a lighter, better choice. Just getting the back deck, rollbar and the rest of the chassis done, then on to the body next week. I decided I wanted more crash protection that took a bit to figure out how to do it light took a bit of time but worth it. Hopefully a totaled Leaf will come up before I get done. So I'm joining the auto auction with an alert when the next one comes up and bid on it. I can't edit so please edit any response. I can't even change the subject anymore thanks to their 'improvements'.

At least 15% of the cells will change so much in the first year the BMS will react to your disadvantage of early charging termination and early over discharging. A one year warranty that is promised is hocus. the second year will experience a 10% failure with no warning of a cell. This makes your car unusable. Further experience with other Chinese cells is no better, or worse. I now sell and use the Nissan Leaf module that is half the price and so far no failures like the CALB. I would not ever recommend a CALB cell to any customer. Those that are pushing the cells like EVTV have inventory they want to unload before their is no more demand for Chinese cells. My customers who have converted to the Volt and Leaf cells, made by the same S Korean manufacturer, are really happier with the results. No more stagnant at rest loses that you have experienced. Look at what cells are used in the popular plugin cars that are required to provide a 8 year warranty in California, no Phosphate. CALB would be out of business if required to provide a 8 year warranty. They don't even recognize their one year warranty. You wonder why you are having problems, wake up and smell the coffee. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/self-discharge-of-CALB-180Ah-LiFePO4-cells-tp4669067p4669069.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) -------------- next part -------------- An HTML attachment was scrubbed...
