These are the batteries from the Hybrid Auto Center that I am going to use. You can get them preassemble or unassembled in metal case modules that contains four cells each connected two in series and then two in parallel for a voltage of 4.2 volts per cell or 8.4 volts maximum per modules at 66 a/h each.
You can assemble as many modules together using threaded rods to fit the space you have. They are copper connections and you can either make your own copper bus bars out of 1/2 inch I.D. A/C pure copper tubing flatten to 3/4 in wide that has no other alloys which are use for the load terminals or you can purchase zinc plated bus bars from them. The length of the bus bars depends if you want to parallel the modules together for increase a/h. There are small sensor terminals that tap into the cells that uses 1/2 inch copper bus bars which also can be made out of 3/8 inch copper A/C tubing. This connection taps are use to connect the BMS circuits to. Each module weighs just over 8 lbs. I am using 54 modules which three modules are connected in parallel for 189 ah and series the three modules for a maximum voltage of 226 volts. For a long life, do not charge to the maximum voltage, best only to charge to about 90 to 95% of the maximum voltage. Do not have your regenerative system on when above 90% SOC or this could damage your batteries or BMS units while driving with the BMS on. If your charger is NON-CAN control or cannot be control by a BMS which allows the current to be taper down to a low level before shut down, you can use a lower maximum charge voltage below 95% which will allow it to shut down with out a tapering current. NO, These are not Chinese batteries that some are having problems with. Made by the Toyota Company which I think that had the license right from GM back in 1993 when they held the patent on them. The patent ran out in 2013 which Toyota is now producing kits to change there hybrids to EV.

Plus kits including BMS. I don't know anything about them, haven't bought from them. It does make sense that "1eyedcruiser" might be the secretive "cruiser" that posts here occasionally. Personally, I would be wary of doing business with anyone that is so secretive. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub<http://www.evdl.org/help/index.html#usub> http://lists.evdl.org/listinfo.cgi/ev-evdl.org<http://lists.evdl.org/listinfo.cgi/ev-evdl.org> For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA<http://groups.yahoo.com/group/NEDRA>) -------------- next part -------------- An HTML attachment was scrubbed...
