Re: [EVDL] LED Taillights - a money saver in gas cars? - >rangeextenderin EV's? - an

just off the top of my head (assuming the PSU would accept the voltage
you supply it with) maybe there is a problem with the very controlled
12v and the 12+v the battery would like to have to get charged up. then
it might work without the battery. but it's just hunchings
