Should to good to be true with super long service life and no acid level to check, plate decompositon and such.

The unit I was looking at is only 90kgs empty and approx 240 kgs with fluid added. Hardly a commercial size unit by any standards.
Have been told they are 48 volts dc with a 8kw capacity.

Quote from a message sent to me.

From memory the ZBM 3 is 48 VDC with 11KWh total capacity

Here's some data I found on an earlier model (Gen 2.8-DC)
Power Range
0kW to 2.5kW during charge 0kW to 3kW during discharge
Net Energy Range 0kWh (0% SOC) to 8kWh (100% SOC) 
DC Voltage Operating Range 40 to 57V DC
Absolute Voltage Range 32 to 72V DC
Quiescent Current Draw 1.5A DC maximum @ 40V DC
In-Rush Current >100A DC maximum @ 40V DC Auxiliary Power  180W maximum @ 32V DC minimum
Operating Battery Temperature Range 5 to 45 °C (41 to 113 °F) (Limited operation from 45°C, shut down at 50°C) Maintenance Cycle Frequency At least once every 120 hours of zinc pump operation.
Minimum Energy Efficiency Performance Requirement 68.0% gross (energy out/energy in)
