Frequently asked questions


The Pico system is already compatible with LiFePO4 lithium batteries.

Generally, all Lead-acid batteries like WET STD., WET FREE, AGM, Deep Cycle, GEL and LiFePO4.


Less than a minute.

Yes. For best PICO experience, it is recommended to upgrade PICO’s firmware to the latest version. You can perform the upgrade via PICO Battery Monitor smartphone application available on your smartphone App market.
The WiFi SSID and Password are generated from your PICO serial number. You can find the serial number on the back of the PICO, on the side of the retail box and in PICO SETTINGS > SYSTEM > System Info.

EXAMPLE: (If your Pico serial number would be 12345678)
SSID: Pico5678
Default password: pico1234


PLEASE NOTE! It is important to download the latest PICO Battery Monitor application before proceeding with the firmware upgrade. Please follow the below firmware upgrade procedure:

Install or upgrade to the latest PICO Battery Monitor application on your smartphone.
Turn on the WiFi connection on your PICO. Connect your smartphone to PICO WiFi network PICOxxxx.

Launch the PICO Battery Monitor App on your smartphone. Go to menu settings and click Upgrade PICO’s firmware to put the PICO in Upgrade mode. The upgrade procedure will take less than a minute.

After the upgrade, PICO will reboot and will be ready for us.

Yes. Free SIMARINE Android and iOS Apps are available to connect your PICOone to your smartphone via Wi-Fi. The Apps allow you to monitor all battery and tank data, upload history, edit and restore settings and even upgrade the firmware for adding new features.

You can download the PICO Battery Monitor app for your smartphone on the links below.

Yes! With PICO battery monitor you can precisely measure the draw of the individual consumers like inverters, bow and stern thrusters, anchor winches, etc. using our SC300, SC500 and SC302T shunts. You can read their exact consumption and even history on your PICO.

You just need to add our unique SCQ25 (4 inputs for up to 25A each) module to your PICO system! The SCQ25 will precisely monitor the current gained from your solars and current drawn by your fridge.

Yes! With PICO battery monitor, you can measure precisely how much power you get from your solar panel, wind and hydro generators and shore power chargers. That is also an excellent tool to detect any possible malfunction – for example – if your solar panels are dirty, they will produce less power, and you will see that on your PICO.

You can monitor your power sources using our SCQ25 and SCQ25T Quadro shunt modules (4 inputs for up to 25A each) or our standard shunts (SC300, SC500, and SC302T).


Not yet. We will add CI-BUS support in Q3 2019.

No yet, currently we do not support NMEA 0183 and 2000 protocols. However, a bidirectional module will be available for purchase in Q3 2019.


Not yet. We’ll add that functionality shortly via the firmware upgrade.

For precise monitoring of the service (house or main) battery bank, a shunt is necessary. Being informed about your battery status is not only for electrical enthusiasts – it is about your safety! In a case of emergency, a power loss can end up badly.

We highly recommend using shunts for heavy consumer batteries like a bow and stern thruster, anchor winch. Such consumers can discharge your batteries significantly in a matter of moment, which means they can also damage the batteries quickly if they are not sufficiently charged.

If you have separate batteries that you only use to start your engines, monitoring only battery voltage will be enough in most cases.

A battery bank is a group of two or more batteries, connected in parallel or series.

By connecting the batteries in parallel, the amperage rating (Amp Hours) increases while the voltage remains the same. For example, three 100Ah batteries on 12V, connected in parallel will result in 300Ah battery bank on 12V.

By connecting the batteries in series, the voltage increases, while the amperage rating stays the same. For example, three 100Ah batteries on 12V, connected in serial will result in 100Ah battery bank on 36V.


Our system and tank modules are compatible with all resistance/resistive tank sensors (Level sensors) 0-65kohm, they exist on the market.


PICO or PICO+ needs at least four cycles of charging and discharging to show real “State of charge” for the battery/battery bank. During this “learning time,” the “State of Charge” is unreliable and should be used with caution.


Your shunts only support up to 500A. What can I do?

No problem! You can get two SC501 shunts and combine them to reach 1000A and so on.

Yes. PICO and PICO+ battery monitors can monitor up to 6 electrical systems (battery banks) at the same time. Each system can be on different voltage level. For each electrical system (battery bank), an Active Shunt is needed. At this time, we support 12V, 24V, 48V, 60V and 72V (using SC302T shunts) and 12V and 24V (using SC300 and SC500 shunts).

You can wire all our shunts to the negative (up to 72 V) or positive side (only on 12 V and 24 V).

However, for battery monitoring, we recommend wiring the shunts on the negative (low) side.

If you are monitoring consumers (e.g. inverter, bow thruster) or generators (shore power charger) with the shunts, you can choose either, negative or positive side.
