The LE300 Smart Battery System is a lithium expansion to increase the capacity and performance of the lead battery, as well as the efficiency and service life of the overall system.

The lithium expansion battery takes over most charging cycles while the lead battery works as a cheap backup storage. The lead battery is loaded with a higher priority, with the lithium battery taking over the surplus energy. When unloading, the lithium battery is primarily unloaded. As a result, the lifespan of the lead battery is significantly extended. The LE300 recognizes the voltage of the lead battery and automatically begins to support the lead battery with a maximum current thickness of 12.5 A. Larger loads are supplied in parallel by the lead battery and the lithium battery, which contains both batteries with less electricity.

All advantages at a glance

Plug & Play> Easy Connection of two cables
Flexible adaptation of the capacity by simply putting together individual modules.
Use of the existing lead loader possible.
Performance optimization of the battery system by loading priority of the lead battery and preferred unloading of the lithium battery
The performance of the lithium battery and the cost advantage of the lead battery are combined.
Slim and light design with variable fastening options.
Integrated heating system.

4 different variants available:
Lithium battery LE300 individual module
Lithium battery LE300 2 Series Block
Lithium battery LE300 4er block
Lithium battery LE300 6 Block

Package PICO One in black

The PICO one package is the perfect battery and tank monitoring solution for smaller boats, campervans, buses and caravans with a service battery bank with up to 300 A at 12 V, 24 V, 48 V, 60 V and 72 V, one or two engine/standby battery banks and up to 2 tanks.

1x PICO one display unit
1x SC303 300 A shunt

SC303 is an innovative combination of shunt and tank level module.

The SC303 active combination shunt ensures precise monitoring of the battery voltage in systems with 12 V, 24 V, 48 V, 60 V and 72 V, the battery temperature and continuous currents of up to 300 A (peak 400 A). It is suitable for a maximum power of 3600 W at 12 V or 7200 W at 24 V. It has an additional battery voltage input (2 in total).

The measuring shunt has 2 resistor inputs for monitoring the tank level or temperature and an additional JST socket for the temperature sensor with JST connection. In addition, the SC303 module can also be used to monitor the power consumption of large consumers such as inverters, bow and stern thrusters and anchor winches and the power generated by generators such as shore power chargers, solar modules, water and wind power generators.

The innovative protected architecture of the SC303 enables connection to either the negative side (up to 72 V) or the positive side (up to 24 V).

Suitable tank sensors: Basically all resistance-based level indicators such as:

Wema sensor for water and fuel S3
Schaudt tank sensor (an adapter cable may be required)

All monitoring functions of the PICO One package:

1x battery bank with Real-Time Battery Health™ (monitoring of amperage, voltage and temperature)
2x battery voltage only
2x tank levels or temperatures
