Hi All;
I have been helping my co-worker with the fleet of golf carts we have,
about 20 of them. The education process has been going slow, I just keep
nudging him in the right direction (in my opinion) on the care and feeding
of the batteries, it's the only thing there having a problem with. When the
cart would no longer last all day on a charge he would just put in a new set
of batteries, what I have found is that it's only one or two stinkers
causing the problem so we built up a surplus of, good, used batteries to
replace the stinkers with instead of replacing the whole pack.
The problem that I'm finding now is an imbalance in the battery pack,
most of the chargers are Lester chargers and they taper to about one amp and
stay there until unplugged or timed out, my plan now is to do a equalization
charge as part of the regulator maintenance on the carts.
Please correct me if the above strategies is incorrect or needs to be
changed.
The charge and equalization charge needs to happen in six hours or less
during the regular maintenance, my first thought was a variac with a
isolation transformer, then there was a bench top power supply it all ready
has isolation, then there was putting the variac in front of the Lester
charger.
I like the idea of the bench power supply, that way I can dial in the
amps and set the voltage high and it will do the 36v and 48v carts, I have
looked but haven't found anything that fits, yet, I'm thinking 70v and 10
amps. What do you guys think.
All help and suggestions for the care, feeding and repair of these
batteries are welcome.
