Unpack Batteries and Check Voltage
1. Unpack the batteries and turn each battery on by itself.
2. Note the voltage of each battery and serial number. The serial numbers are useful during warranty submittal.
3. The batteries must be within +/-0.5V of each other before commissioning. Groups of 4 batteries or more may require a narrower voltage range to commission properly.
4. Turn off the batteries and install them in parallel. Notes

Unpack Batteries and Check Voltage

1. Unpack the batteries and turn each battery on by itself.

2. Note the voltage of each battery and serial number. The serial numbers are

useful during warranty submittal.

3. The batteries must be within +/-0.5V of each other before commissioning.

Groups of 4 batteries or more may require a narrower voltage range to commission

properly.

4. Turn off the batteries and install them in parallel.

Notes

If the battery voltages are significantly different, one technique is to finish battery

installation and only turn on the lowest voltage battery using the pushbutton.

Charge the battery, and when the charging voltage is ~0.2V above the resting

voltage of the next lowest battery, turn it on too. Proceed until all batteries are

turned on and at the same voltage level. If the batteries are below 51V, keep

charging amperages below 10A per battery.

If the batteries are slightly more than +/-0.5V from each other, turning on the

highest voltage batteries only will reduce their voltages, and turning on the lowest

voltage batteries only will lower the highest voltage. Likewise, turning on the lowest
