any one know how to charge a 12 battery s? i am try to build a electric car with 12 batteries total 120 volts . but how i do charge ??? can any one help me , where i get the parts
Twelve 12 volt batteries in series would be of course 144 volts, "niminal". With the proper charger you can charge a series string of batteries. One problem that occurs is that the batteries eventually get out of balance, so you need to have some sort of Battery Management System or a way to equalize them. Another way is to use individual chargers for each battery.
You need to do some internet searching on this and learn more. Check out the Electric Vehicle Discusson List
Thank you for the compliments. Yes I spend a lot of time scanning the Battery Monitor gauge, just to be sure the pack is healthy. I just returned batteries 3 and 7 as they were getting worse and worse.
I still do look at Volts and Amps as I am still tryting to determine the best performance I can get.
I can't even imagine having 80 Li cells and trying to make sure that they are healthy. I guess that is why a real BMS is needed for Li! ô¿ô
No, unfortunately I have no reliable place to charge. Also I take the train 3 days a week. It would make a nice station car if there was charging at the station and if it wouldn't get vandalized...

Nice implementation, Dave. Much cleaner installation than mine! :)
Correct me if I'm wrong, but has this become your "most looked at" gauge? I tend to monitor my bargraph more than amps/volts.

that is cool. It's a nice setup. now you can monitor your batteries while you drive. Thanks for posting. Ernie

Nice job Dave, looks like #7 is dipping more than the rest.

Yes , I agree, looks like I've got a weak battery. That is exactly what this monitor is made for.
