In case you were wondering… I hooked up a 12v battery on a charger to the 12v side of the step down transformer and only got 12.8v on the 48v side of the transformer, so that doesn’t work…. Never mind! Lol
Are there 36/48v stereos and lights? I know there are but as a practical matter many many more at 12v. So there must be a step down transformer on the cart to use 12v stuff. Does anyone know if you can hook 12v to the transformer and get 48v on the other side?
We drove into Duck Creek for breakfast on the way back from Bryce Canyon in July. Go check out all the private strips and wish you had a tail dragger for the weekend!
90% discharge on your battery’s is going to be asking a lot of a friends donor cart to jump you… I would punish myself and check each battery and recover the batt bank the hard way by separately reconditioning each battery.
While 48v in general isn’t going to kill you, it is only a few volts away from killing you. Any attempt to hook up additional batteries without determining what the current state of charge is and checking the voltage is weak advise.
Could have a blown fuse, broken ground strap, burnt wire, bad...
I would do it if that’s was my only option, but not without monitoring the voltage increase with a meter. As soon as I saw 7v I would stop and move to the next battery…
Start with a volt meter. Check the total in series battery bank (48v) and then do each separately. Most likely they can be charged but the battery charger isn’t going to kick on if the bank is below what the charger needs to tell it that it’s safe to charge.
The battery charger should have...
Only in the social media era would creating a new government bureaucracy to somehow fix government bureaucracy be even considered. Or better yet spend money on a commission to recommend how to save money with no ability to actually enforce recommendations and save money..
I never said he was a bad business person? I said it was “ironic”. I find it ironic to put a person in charge of government efficiency who made a fortune feeding off of an inefficient market where subsidies fueled his success.
I am pretty sure many ended up in landfills…. If a farmer (which there were many) had their own pole and transformers on a well pump, the old transformers ended up in a quickly dug hole.
Probably not as big of an issue in the future as they phase out the nickel and cobalt batteries… the newer iron phosphate doesn’t have the same thermal runaway issues as the older lithium chemistry’s. But who knows, storing energy always has risk.
