charging batteries

[plumberdad70]

is it ok to each battery by itself until i can get a 48 volt charger and do i have to unhook them from the pack to do so?

It's ok, but not great. No need to disconnect.

just until i get a 48 volt charger so i can test the cart and make sure everything else works

You can charge your batteries individually, but will want to use the largest amp rated charger you can find, as golf cart batteries take quite a bit of amps to charge effectively.

For example, for a Trojan T-105 (a popular 6 volt battery at 225 amp-hrs), the recommended Bulk Charge interval (at constant current) is 22 to 29 amps. The recommended Absorption Charge interval (at constant voltage) is 2 to 7 amps.

I have tried topping off single 6 volt batteries with a 1.1 Amp NOCO Smart Charger (the only 6 volt charger I own) and it barely tickles them ... it might take a week to just top them off from a slight discharge. The same batteries when connected in the pack, have no problems charging with my much higher rated 22 amp x 48 volt charger.

So grab a large amp charger if you can ... otherwise it might take a week of Sundays to charge your 6 or 8 batteries individually.

Let us know how you make out. You can't hurt the batteries by charging them individually, but it might take a lot of time depending on the amp rating of your 6 volt or 12 volt charger (not sure what voltage batteries you are using).

Find attached a State of Charge chart for your reference so you can determine the percentage of charge on your batteries.

mine has 4 12 volt batteries and i have a 30 amp 12 volt charger. so that should be ok for now until i can order a 48 volt charger. i just want to make sure this cart is in working order befor i go trowing a bunch of money at it for upgrades and such.
