devices from the battery (even battery monitors), first connect the
inverter, wait 45 seconds and then connect the remaining devices.

Do high temperatures affect how the batteries perform?
○
Yes. Similar to lead acid batteries, the battery cycle life will be reduced if
they are regularly charged and discharged above temperatures of 100
degrees F.
17.
Do low temperatures affect how the batteries perform?
○
Yes. Below freezing, to protect the battery cells, the HLX BMS will not
allow charging. Also, the battery capacity reduces by 20% between room
temperature (approximately 77°F (25°C)) and just above 0°C (32°F).
○
The CHLX batteries are a special case. At 0°C (32°F), if there is a charging
current, the CHLX will try and warm themselves up to 10°C (50°F).
■
Because of this, you cannot mix HLX and CHLX in situations where
the battery bank will go below freezing.
18.
Why is the voltage shown in HLX iT not the same as what is measured at
the terminals?
○
The gap between the volts shown in HLX iT and the volts measured at the
terminals can be as large as 0.3 V, especially near the middle of a charge
/ discharge cycle. The gap closes at the beginning and ends of a cycle.
19.
Why does HLX iT show my battery at 100% SoC when the battery voltage
hasn’t reached 14.1 V? Why are my batteries showing different States of
Charge (SoC) even though they are at the same voltage?
○
The SoC needs to be re-calibrated. Please try re-calibrating the battery
SoC by doing the following:
■
Charging the HLX all of the way up to 14.1 V. If the SoC reaches
100% before the battery is at 14.1 V, please do not stop charging.
Keep charging all of the way to 14.1 V.
■
Then Discharge the HLX all of the way to 12V.
■
Then re-charge the HLX normally, once again up to 14.1V.
○
The SoC should now be re-calibrated.
Remember, the SoC reported in the app is an approximation for people to use,
but the battery behavior is actually driven by the Volts and Amps.
20.
My 1800 HLX is stuck in a protection mode. The voltage is in the single
digits and it does not show up in HLX iT. How do I wake it up?
○
If your HLX has a reset button, press it for 5 seconds. That should wake
the HLX. Currently, only the 1800 HLX has a reset button.
