Did someone say Christmas?!?.. but uh.. should I be concerned that it says 72-96v when I have a 120v system planned?

Nice motor! No, you shouldn't be concerned at all about the voltage label. My ADC K99-4007 says 48 volts, but the motor is designed for up to 96 volts, which is what I am going to use it at.Did someone say Christmas?!?.. but uh.. should I be concerned that it says 72-96v when I have a 120v system planned?

I won't have AC... decided against it as it wasn't working properly in the ICE..will 25 amps be enough for the car????? are you using AC? My car bare bones with lights on heater fan on and a blinker will draw 32 + amps,,, as long as you are not there very long and the 12 battery is big enough you will be OK I am sure. My 12 VDC battery is only 10AH.
what size is your 12 volt battery for the car???I won't have AC... decided against it as it wasn't working properly in the ICE..
You know, I was concerned that 25amps wouldn't be enough, but the guy at beepscom assured me I'd be fine. Bottom line, it's cheap enough to make it worth the try! If I end up needing a bigger one, no big deal really.
hmmm... that could work if it ends up not being big enough... 50amps should be plenty.. I was thinking of just using the battery that was in the car.. not a good idea?what size is your 12 volt battery for the car???
also if the conertor is not not big enough you can get a second one and add it in parallel to the existing one and double your out put
that will be OKhmmm... that could work if it ends up not being big enough... 50amps should be plenty.. I was thinking of just using the battery that was in the car.. not a good idea?
Much of it depends on the size of the battery you plan to use for the 12 volt system of the car. A large enough battery can be charged seperatly and if you do not do to much night driving it will probably be OK, The advantage of a dc convertor is you will never run out of power and the draw on the traction pack is not very high, for example 21 amps at 12 vdc out put is 252 watts out put not that the dc convertor is 100% efficient but lets say it is for this example if your traction pack is 120 volts you will be using just over 2 amps of current from the pack to supply the power to your 12 volt system,,,, pretty insignificant all things considered.Now I am concerned My DC/DC is only 21 amps.
I had planned on using the stock battery for accessories or replace with a AGM battery of about 40AH. Perhaps I will have to replace all the lamps with LED type
I have heard so many different ways of dealing with the 12 volt, including separate charger for 12 volt and no DC/DC at all.
I guess whatever gets the job done..
I have heard that some do the dc convertor on the traction pack and don't even use a 12 volt battery,,, Iguess it will not draw hardly any current at idle? I am not going to do it but????? It would be interesting to see if ya did,, although if you have a seperate battery that it is responsible to charge the voltage would be to high(probably) as in "float" mode I do not think you would want more than 13.7 max,, and if the dc conv was set that low it may not fully charge the 12 volt battery,, hence the reason it should be on the contactor side or don't use the 12 v battery at all.My DC/DC is 55 amp and I used the same battery as Brian. I havent really tested it yet but Brians comments on his thread have me worried as right now I have my DC/DC on the batt side of my contactors. Now that I have that SLA I want to move it to the controller side so its only on when the system is on to stop battery drain.
Just some thoughts as I'm working on that system now......
also Ben that battery didn't hold up so well for me ,, did ya notice how light it was???
not sure thats necessary I just think tha batteies we got were a bit how do I say" cheasy" I don't doubt that a 60 dollar version would have worked just fine,, Sorry man!!!I sure did and the fact that my car has a little more voltage requirement than yours worries me. I may have to go back to the original, although smaller 12V car battery. It's mounted in the rear of the car so luckily room won't be an issue.
