High Voltage UBA5


The UBA5-44V, UBA5-60V and UBA5-70V can analyze batteries that are higher in voltage.

Note: UBA5-60V and UBA5-70 are back ordered until mid March 2017.

SKU: UBA-44V-60V-70V Categories: ,


Analyze batteries that are higher in voltage than the standard UBA5 as shown below:

Chemistry Maximum Battery Rated Voltage Maximum Number of cells
Lithium Ion or Polymer 37V 10
Lead Acid or Gel Cell 36V 18
NiCd or NiMH 30 25

Maximum input of 60V, can analyze high voltage battery packs, as follows:

Chemistry Maximum Battery Rated Voltage Maximum Number of cells
Lithium Ion or Polymer 51.8V 14
Lead Acid or Gel Cell 48V 24
NiCd or NiMH 43.2 36

We also have a 70V UBA5 for 16S li-poly batteries:

Chemistry Maximum Battery Rated Voltage Maximum Number of cells
Lithium Ion or Polymer 59.2V 16
Lead Acid or Gel Cell 56V 28
NiCd or NiMH 49.2 41

UBA5-70V Brochure

the UBA-44V, UBA5-60V and UBA5-70V come a small power supply (120VAC or 220VAC input) that powers the UBA5’s internal circuitry. The maximum charge current is 2A per channel (up to the charge power supply’s limit) and the maximum load is 2.4A per channel with a 45W limit per channel. You can use the UBA channel combiner to charge at twice that.

The charge power supply, which we don’t supply, needs to be of sufficient voltage and current to charge your batteries. The UBA5 will regulate the charge current.

Here are some suggestions (Links to Google Search):
Instek PSP-405: 40V 5A
Instek PSP-603: 60V 3.5A
Instek GPR-7550D: 75V 5A
Instek SPS-606: 60V 6A

When testing batteries that are higher than 15V the UBA5’s power limit becomes the limiting factor during battery discharge. For example, the maximum discharge current on a 30V battery would be 1.5A (45W). If you want a higher current for the discharge then see our section on High Power Solutions.

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.
