That narrows it down to about a half dozen makes and models.
However, odds are very high, nearly 100%, that it is designed to charge Trojan brand batteries, so it undercharges US Battery brand batteries.

The DPI Accusense has a user selectable charge profile for US Battery and is the best bang for the buck.

Here is a Voltage vs SoC chart for US Battery. The voltage readings are taken 12 hours after the charger shuts off automatically

In addition to the batteries being undercharged, check the cables and connections. If any are getting hot, they need to be repaired/replaced.

Also check the throttle input signal to the controller. J4 Pin-3 (black wire) should be 0.7V to 1.3V when solenoid clicks and 2.5V to 3.3V when pedal is on floor.
