High Current UBA5


Ideal for testing lithium ion single or two cell batteries.


This is the high current version of the UBA5 with a 6A or 10A per channel maximum load current. It is designed for testing of lithium ion single or two cell batteries. Both channels can be paralleled for 12A or 20A of load current!

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.
