AVENTURA BATTERY

The Aventura series batteries are designed to be used with a maximum of 4 unit connections, in series OR parallel. They are ideal for Off Grid caravanning, recreational vehicles, solar powered, boats (utility) or any application requiring the use of a deep cycle battery.
They are equipped with a BMS “Battery Management System” which monitors, optimizes and protects the batteries in order to ensure a safe and precise operation.

GENERAL BMS FEATURE

• High voltage: (+ 16.7 V)
  If an individual cell voltage exceeds a prescribed threshold while charging, the BMS will prevent the charging current from continuing. The discharge is always allowed under this condition.

• Low voltage: (- than 10 V)
  If an individual cell falls below a prescribed threshold during discharge, the BMS will prevent further discharge. Although the battery is in “low voltage disconnection” mode, it will still allow a charging current.
  Several chargers must detect a voltage greater than 10 V to send a charge to the battery.

• *High temperature: (+ 55-70 o Celsius)**
  The BMS will not allow a charge or discharge current.

• Depending on the model, refer to the technical sheet for more details.

• Low temperature: (- 20 to 0 o Celsius)
  The BMS will either prevent charging or use it to heat the cells for self- heating models.

• High charge current
  The BMS will not allow a charge current that exceeds 100A (+/- 5%) amps for 30s, or 200A (+/- 10%) amps for 0.5s.

INSTALLATION

The batteries can be mounted in any orientation. Exercise caution when connecting to the battery terminals. The positive and negative terminals are labeled and color coded (red for +, black for -).
Do not reverse the polarity of the battery, as this will damage the battery and the connected device.

Parallel
Up to 4 Aventura batteries (of the same production series) can be connected in parallel to increase the capacity of the system. When the batteries are connected in parallel, the system voltage does not change, but the amperage will add up. Therefore, all cables and connections must be able to withstand the high currents that can be delivered by the battery. Appropriate fuses and circuit breakers are also required to protect downstream components from current peaks and short circuits. The batteries to be connected in parallel must be at the same state of charge before connecting. To ensure that, fully charge each battery using a 12V charger before connecting them in series.
To distribute the current evenly between the batteries, use the diagram below

Series
Up to 4 Aventura batteries (of the same production series) can be connected in series to increase the system voltage up to a 48V system. When the batteries are connected in series, the current capacities will remain the same, but the system voltage will add up.
The batteries to be connected in series must be at the same state of charge before connecting. To ensure that, fully charge each battery using a 12V charger before connecting them in series.

Disconnecting the battery
First, disconnect the negative cable from the battery terminal (-) and then disconnect the positive cable from the terminal.

Inverters / Chargers
Do not connect batteries to an inverter / charger greater than 3500 Watts without a surge arrester, this will damage the BMS and create a potential fire hazard.
Battery chargers without a specific lithium charging algorithm are compatible. However, a charger that has an automatic equalization mode, must be disabled or set to 14.4V.

SECURITY POINTS / WARRANTY CANCELLATION

• DO NOT CONNECT IN SERIES OR PARALLEL WITH OTHER TYPES OF BATTERIES (ACID / LEAD, AGM, GEL OR LITHIUM FROM ANOTHER SERIES)
• DO NOT LEAVE THE BATTERY DISCHARGED (- 11.5V) OVER A LONG PERIOD.
• DO NOT IMMERSE THE BATTERIES
• DO NOT SHORT-CIRCUIT THE BATTERIES
• DO NOT INVERT THE POLARITY
• DO NOT EXPOSE BATTERIES TO EXCESSIVE HEAT.
• DO NOT DROP, PUT DOWN, DISCARD, OR APPLY EXCESSIVE FORCE TO BATTERIES.

CHARGING THE BATTERY

You can recharge your Volthium batteries after each use or when they have been discharged up to 80% (20% SOC). If the BMS disconnects the battery due to low voltage (100% discharged) remove the load to reconnect the battery circuit and recharge immediately.

Charging with lead battery chargers
Most lead battery chargers can be used with Volthium batteries as long as they meet the proper voltage guidelines. The AGM and Gel algorithms generally match the voltage requirements of our batteries. The voltage for standard Acid / Lead battery charging algorithms is often higher than the LiFePO4requirements, which will cause the battery to be disconnected by the BMS at the end of the charge cycle and possibly display an error code. If this happens, it is recommended to replace your charger with a lithium function charger. Since the BMS protects the battery, using lead chargers will generally not damage the battery. However, it must be disconnected after the battery is fully charged. Do not leave the charger in place to maintain or store the battery.

Load parameters
Volthium batteries can be charged in 1 or 2 steps:

1 Step mode: Bulk – Will charge the battery to approximately 95%

• Voltage 14.2 – 14.6 V
• Amperage 5-40 A

2 Step mode: Bulk and Absorption – Will charge the battery to 100%.

• Voltage (Bulk) 14.2 – 14.6 V
• Voltage (Absorption) 14 – 14.4 V
• Amperage 5-40 A

For the initial charge, it is recommended to leave the battery under charge for 4 hours after it displays a voltage or a % of completed charge.
A fully charged battery disconnected from any charging source will see its voltage drop back into a range of 13.2V to 13.6 Volts in the following hours.

Series or parallel connection

• When connecting batteries in series or parallel, make sure that each battery is within 500 mV (0.5 V). It is recommended to fully charge the batteries individually once a year to avoid imbalance. When charging Volthium batteries in series, it is best to use a multi-bank charger which charges each battery individually to ensure that the cells remain balanced.
• If you are charging batteries in series or in parallel with a single charger for the entire system, set the charger to 14V. If your charger voltage is lower, the battery will be undercharged and will not provide its full rated capacity. If your charger voltages are higher, the BMS will disconnect the battery circuit and you will need to remove the load to reconnect.

Charger / Inverter and charge controller

Volthium batteries do not require equalization.

Alternator
To protect your battery and alternator, be sure to use a high quality compatible alternator. Current and voltage spikes associated with substandard alternators or high load can cause the Volthium batteries to be disconnected by the BMS. If the BMS disconnects the batteries, the alternator may be damaged. Otherwise, the addition of a DC to DC type voltage regulator is recommended.

Storage
Before storing your batteries, charge them between 50% and 80% and then disconnect them from any charge or discharge.

BLUETOOTH FUNCTION AND SELF-HEATING FUNCTION

Adding the Bluetooth function

• PLEASE NOTE: to obtain the Bluetooth functionality, you need to add a Bluetooth module to your battery (not included with the battery). Download the “Volthium Monitor” or “Energy Volthium” application, which can be found in the Apple AppStore or the Android PlayStore.
• By opening the mobile application, it will direct you to the battery “Scan” detection menu. It is not required to go to your mobile device settings to establish a Bluetooth connection. No pairing button needs to be pressed to pair your battery with your mobile device. The app will detect your nearby battery within a radius of less than 6 meters.
• The data provided in the application will be accurate once the battery is fully charged with a compatible charger.
• When the battery is in standby mode, the voltage data on the battery terminals and on the application may deviate up to 0.7 V. When in charge or discharge mode, the data will match. The voltage on the application is always the most accurate since it is taken directly from the cell block.
  You will find valuable additional information on the Bluetooth functionality in the FAQ section

Operation of the Self-heating function
For the batteries with a self-heating system, it will be activated when the internal temperature drops below zero. Thus, when the battery is connected to a charger or to any other power source, the BMS will first use the current to bring the internal temperature to 11 degrees and then start charging the battery. The power source must be at least 5A for the self-heating system to start. Your Aventura will be able to go from -20 degrees to 11 degrees in just 2 hours.
