>I have a Manzanita Micro PFC20 charger.? According to the manual (and searching prior posts) this charger can function with a DC input. Specifically I want to charge a 48V pack from a 148V pack Has any actually used this charger with a DC input?,<
I've had mixed luck doing this but I often find I need to drain down a pack and watch the batteries as they drain which is hard to do while driving . So I'll charge another car's pack using one of my Manzanita chargers and power it off the cars battery that I want to watch. Some do's and don't s : Always start the charger with the current knob on OFF ( don't plug in with ON and current turned up ) . The charger won't current limit well when running off dc so if you don't want full charger amps going into or coming out of your pack, you could have a problem. Don't unplug either pack while charger is running . Don't turn OFF the charger with a breaker without turning current knob OFF . Might be best not to use the breaker at all as its not really rated for DC , but as long as the current knob is turned OFF I have not had a problem this way . One of the things I like about Riches Manzanita charger is that I can use it to drain one pack into another .. but one must turn the current knob down before any power is applied . Don't try to charge the 12v battery in the same car off it's traction pack as there may be some current leakage from traction pack to frame . I'd be interested to hear what Rich say about it ,,, I wouldn't loan my PFC to somebody for doing this but I do do it often myself and I still have one of his older models ( the one with the ears added on ) . -- Steve Clunn Merging the best of the past with the best of the future. www.Greenshedconversions.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)
