Batteries @ 60vdc when charging

what is the purpose of equalizing charge?
how often does this need to be done or if at all?

[WalterM6]

It's to keep the batteries in balance. All of them should read within a tenth of a volt of each other. I do the equalization charge on my batteries once a month. It takes 2 or 3 hrs longer after the normal charge.

For your reference, find attached the Trojan specification on charging voltages. There is some useful information here to compare to, for each stage of the charging cycle including the equalizing cycle.

And further to WalterM6's explanation (who pretty much captured it in one line ), below is the Trojan longer winded explanation for equalization, which come from page 22 of the attached Users Guide.

4.4.3 Equalizing (deep-cycle flooded/wet batteries only)

Equalizing is an overcharge performed after fully charging deep-cycle flooded/wet batteries.

An equalizing charge prevents battery stratification and reduces sulfation which are leading causes of battery failure.
Trojan recommends equalizing every 30 days or when batteries have a low specific gravity reading after fully charging, below 1.235, or have a wide ranging specific gravity of >0.030 points between cells.

Deep-cycle AGM or gel batteries should NEVER be equalized.

Equalization can be performed either automatically (as programmed on the charger) or by following the procedure below:
- Check the battery’s electrolyte level in each cell to make sure the plates are covered before charging.
- Check that all vent caps are secured properly on the battery before charging.
- Set charger to equalizing mode.
- The batteries will gas (bubble) during the equalization process.
- Measure the specific gravity every hour. Refer to Table 7 for specific gravity and voltage measurements.
- Discontinue the equalization charge when the specific gravity no longer rises.

*** WARNING - Do not equalize deep-cycle AGM or gel batteries.

i have a stock cart with obc and powerdriveII, will equalizing charge work here?

Yes
