Which UBA is best for you?

All UBA5 models have two channels and can network with each other.  They differ by their maximum battery voltage and load current.

Analyzer Power supply included Maximum Battery Voltage2 Maximum Discharge Current/Power
per channel(double the current & power when paralleling both channels)
Maximum Charge Current
per channel(double the current when paralleling both channels)
UBA5 yes 18.5V for lithium ion 3A / 45W 2.0A
UBA5-High Current yes 18.5V for lithium ion 12A / 45W 2.0A
UBA5-High Voltage small1 Up to 59.2V depending on model. 2.4A or 3.0A / 45W 2.0A

1 The small power supply is for powering the UBA5 only, it does not provide the charge current.

2 The maximum battery pack voltage depends on the battery chemistry.


  • All UBA5s come with a serial and USB cable, battery cables, software, manual, and unlimited technical support from our engineering department.
  • All UBA5s can discharge at up to 3A per channel (2.4A for UBA5-60V/UBA5-70V) with a 45W per channel limit
  • All UBA5s can test battery packs down to a single cell, any chemistry
  • All power supplies are universal input, i.e. they work in North America, Europe, or Asia.
