Orion TR Smart 12/12 -30

Hi I have a Question regarding charging profile and outcome.

My two Orion 12/12-30 charges two 90 amp SuperB batteries from the starter battery. The out voltage is set to 14,4 V in both Bulk and Absorbtion, but the real voltage on the batteries are only 13,8-13,9 ( Temp on the orion is 25deg) until they are up to 96%.

The bulk phase continues to 97% then goes over to absorbtion and reaches 14,4V. Absorbtion phase delivers 0,3-0,4 amp for a long time until it goes into Float mode after more than a half our in 100% charge.

My question is Why is it only 13,8-13-9 on the batteries, and why it takes so long time until it goes into float mode?

Long absorption is normal and intentional.

Please post all the settings from the Orion.

What are your batteries? AGM/Gel/Lithium?

Where/how are you reading voltages/state of charge

Thank you for reply.

The settnings on the Orions are

Boost 14,4V 3 hours

Absorb 14,4V 8 hours

Float 13,8 V

The SuperB batteries are Lithium with internal BMS charged via the Orions from AGM starter. Voltage , current and charge status on the batteries are from the Battery Bluetooth and from the Orions Bluetooth.

The current during boost is approx 26-28 amp/orion until 85% and 24 amp until 90 % all time only 13,8 to13,9 on the batteries.

At 97% it goes into asorb and the current drop to 0,3- 0,7amp nd the voltage rises up to the preset 14,4 V.
