ICECO Battery Protection Settings (LOW, MED, HIGH) Explained

The cut-off and restart voltages for each ICECO battery protection level, which level to use with a starting battery, a house battery or a power station, and how to change it.

Every ICECO compressor fridge has a three-level battery protection setting. It switches the fridge off when the supply voltage falls to a set point, so the fridge can't flatten the battery you need to start your vehicle, and switches it back on once the voltage recovers. Picking the right level is the difference between cold food and a fridge that keeps cutting out.

Cut-off and restart voltages

These are the values in ICECO's current VL45ProD and GO20 manuals. The display shows the level as one bar (LOW), two bars (MED) or three bars (HIGH).

Level	12V cut-off	12V restart	24V cut-off	24V restart
LOW (1 bar)	9.6 V	10.9 V	21.3 V	22.7 V
MED (2 bars)	10.4 V	11.7 V	22.8 V	24.2 V
HIGH (3 bars)	11.1 V	12.4 V	24.3 V	25.7 V

Older ICECO manuals (VL Pro single and dual zone, VL60D and JP) list MED slightly lower, at 10.1 V cut-off and 11.4 V restart on 12V (22.3 V and 23.7 V on 24V). LOW and HIGH are the same in every manual we checked. Values can differ on other models, so check the manual for your fridge.

Which level should I use?

HIGH: plugged into your vehicle's starting battery. It cuts out earliest and leaves the most charge for the starter motor.
MED: a general default. ICECO's app recommends medium.
LOW: a separate house battery, lithium battery or power station. There's no starter to protect, and you want to use as much of the battery as possible. ICECO specifically says to use LOW when running from an external power bank.

Lithium (LiFePO4) batteries hold a high voltage until they are nearly empty, and most have their own battery management system that disconnects at low charge. On a lithium house battery, LOW avoids nuisance cut-outs from the brief voltage dip when the compressor starts.

How to change the setting

VL45ProD, VL45ProS and VL60ProS: with the fridge on, press the battery protection button (marked A in the manual) to step through the levels.
VL60D: with the fridge on, press the Mode button.
GO20: in standby, hold the right zone's up and down buttons for 3 seconds, press A to select battery protection, then choose the level with up or down. You can also set it in the ICECO app.
APL55: through the settings menu, or in the ICECO app.

Our ICECO app setup guide covers changing it from your phone.

The fridge keeps cutting out with E1

E1 means the voltage reached the cut-off. If your battery is well charged, the likely cause is voltage drop in the wiring when the compressor starts. ICECO's advice is to lower the level; the better long-term fix is heavier cable from the battery to the fridge. More in our ICECO error codes guide.

FAQ

Will LOW damage my battery?

9.6 V is a deep discharge for a lead-acid (AGM or flooded) battery, and doing it often shortens its life. Use LOW mainly with lithium batteries and power stations that have their own protection.
