Batteries group 24

Our Group 24 batteries are designed for use with off-grid caravans, RVs, solar, boats (service) or any application requiring the use of a deep cycle battery. These batteries can be connected in series to provide a battery bank with a maximum voltage of 51.2 volts (for example, a maximum of four 12.8 volt batteries or two 24 volt batteries).

They are equipped with a Texas Instrument “Battery Management System” BMS that monitors, optimizes and protects the batteries to ensure safe and accurate battery operation. Note that the 51.2V 100AH battery is equipped with a Microchip Technology BMS.

General characteristic of BMS

The Battery Management System (BMS) is designed to monitor the battery’s charge, current, and temperature. When the BMS detects that the battery or battery cells exceed programmed thresholds, the battery will enter a “protection” state. In this state, the external battery terminals are disconnected from the internal battery cells. The BMS will bring the battery out of the protection state once the reconnection parameters are met. Please refer to your battery’s technical specifications for the specific disconnect (protection) and reconnection parameters for that battery.

High voltage protection:
If the voltage of an individual cell exceeds a prescribed threshold during charging, the BMS will prevent the charging current from continuing. Discharge is still allowed in this case.

Low voltage protection:
If an individual cell falls below a prescribed threshold during discharge, the BMS will prevent further discharge. Although the battery is in “low voltage disconnect” mode, charging is still allowed in this state. A battery disconnected at low voltage will have zero volts on the external positive terminal. Many chargers must detect a voltage greater than 10V in order to send a charge to the battery.
Note: Some battery chargers will first check to see if a battery is connected before starting the charge process. Although a battery in low voltage protection will accept a charge current, some “smart” battery chargers may not start the charge process because a battery in “low voltage disconnect” protection has 1 volt or less on the battery terminals. In order to recharge the battery, your battery charger may need to be “tricked” to start the charge process. Please contact Volthium Technical Support if you suspect this is the case. If possible, it is best to program your inverter’s LBCO (Low Battery Cut Out) setting to shut down before the battery BMS detects a low voltage condition.
Example: For a 12V inverter system, set the LBCO setting to 12V. The inverter should shut down when the battery BMS detects a low voltage condition. The inverter should shut down when the battery(ies) still have approximately 10% state of charge. For a 24V inverter system, the LBCO setting can be set to 24 volts. Since the inverter shuts down before the batteries go into low voltage protection, charging issues with smart chargers can be avoided.

*High temperature protection: (60°C in discharge | 45°C in charge)**
When discharging, the battery BMS will enter protection mode if the battery temperature exceeds 60°C. It will not allow a discharge current. When charging, the battery BMS will enter protection mode if the battery temperature exceeds 45°C. It will not allow a charge current.

  • Refer to the data sheet for more details.

Low Temperature Protection: (-30°C in discharge | 0°C in charge)
During discharge, the battery BMS will enter protection mode if the battery temperature is below -30°C. It will not allow a discharge current. When charging, the battery BMS will enter protection mode if the battery temperature is below 0°C. It will not allow a charge current. In low temperature conditions, Volthium batteries with the self-heating option will use the charge current to activate the battery’s internal heating pads. Once the cell temperature has reached the prescribed level, the BMS uses the charge current to recharge the battery cells.
Please refer to your battery’s data sheet for more details.

High charge and discharge current protection
The BMS will not allow a charge or discharge current that exceeds the thresholds prescribed by Volthium. Please refer to the battery datasheet for specific details regarding current thresholds.

Installation

Care should be taken when connecting to the battery terminals. The positive and negative terminals are labeled and color-coded (red for +, black for -). Do not reverse the battery polarities, as this will damage the battery and the connected device.

Parallel
Batteries can be connected in parallel to increase the amp-hour capacity of the system (please note that if you have more than 2 batteries in parallel, we recommend using a busbar to interconnect the batteries and the rest of the system. The busbar must be able to accept the DC capacity of all the batteries added together). When batteries are connected in parallel, the system voltage does notchange, but the DC and amp-hour values are added together. Therefore, all cables and connections must be capable of handling the high currents that can be delivered by the batteries. Appropriate fuses and circuit breakers are also required to protect all components from current spikes and short circuits. Batteries to be connected in parallel must be in the same state of charge before being connected. To avoid excessive discharge currents from one battery to another, please charge each battery using a suitable LiFePo4 battery charger to ensure they are all at the same state of charge or voltage.
To distribute the current equally between the batteries, use the diagram below:

Series
Up to four 12.8V batteries (same series) or two 24V batteries (same series) can be connected in series to increase the system voltage to a maximum of 51.2V. When the batteries are connected in series, the current capabilities remain the same, but the system voltage is increased.
The batteries to be connected in series must be at the same state of charge before connection. To avoid over-discharge from one battery to the next, please charge each battery with a suitable LiFePo4 battery charger to ensure that they are all at the same state of charge or voltage before connecting them in series.

Battery disconnection
Disconnect the negative cable from the (-) battery terminal first, then the positive cable from the (-) battery terminal.

Inverters / Chargers
Do not connect batteries to an inverter/charger over 1000 Watt without a surge protector as this may damage the BMS and pose a potential fire hazard.

Here is an example of wiring a Bluesea battery disconnect switch with an inverter capacitor pre-charge resistor. When connecting the battery(ies) to the inverter, the user first selects switch position 1 for about 10 seconds. The battery current will flow through the 25W resistor to “slowly” charge the inverter input capacitors. After 10 seconds, the switch can be moved to position 2 to directly connect the battery(ies) to the inverter input. Volthium recommends using a 25 ohm / 25 watt resistor to avoid excessive instantaneous discharge when first connected to the inverter.

Battery chargers / solar controller
Battery chargers without a specific charging algorithm for lithium (LiFePo4) are compatible. However, if a charger has an automatic equalization mode, it must be disabled.

Communication

The battery has an XLR port that allows communication to Volthium compatible accessories.

Waterproofing

The battery is equipped with a black rubber cap that is essential to maintain the battery’s waterproofness. It is necessary to install it correctly to avoid infiltration. Note that there is still a sealant on the inside (epoxy / Silicone) of the connectors to provide a safety barrier, but external protection remains essential and mandatory to maintain the warranty. If the battery is installed in a humid environment conducive to condensation, or in a place where rain can reach the battery, it is important to place the battery in a waterproof case to preserve your warranty.

Charging the battery

You can recharge your Volthium batteries after each use or when they have been discharged to 20% (state of charge). If the BMS disconnects the battery due to low voltage (0% state of charge), recharge it immediately.

Battery charger / solar controller
Battery chargers with a specific charging algorithm for lithium (LiFePo4) are compatible with Volthium batteries. If a charger does not have a LiFePo charging parameter, check if it offers the possibility to define a custom or user battery. You can then define and adjust the charging parameters for Bulk/Boost, Absorb, Float values provided in the battery datasheet. Note that the automatic equalization mode must be disabled and temperature compensation during charging is not necessary.

Charging with lead-acid battery chargers
Most lead acid battery chargers (AGM, Gel, FLA) can be used with Volthium batteries as long as they meet the proper voltage guidelines. AGM and FLA algorithms generally match the voltage requirements of our batteries, but will not charge them beyond 90-95%. To charge them to 100%, we recommend replacing your charger with a lithium-based charger. Since the BMS protects the battery, using lead acid chargers will generally not damage the battery. However, the charger must be disconnected once the battery is fully charged. Unlike lead acid batteries, Volthium LiFePo batteries do not require a “trickle charger” to maintain their SOC at 100% when the battery is stored for one or more months.

Battery charging settings

Please refer to your battery’s datasheet for charging instructions.
Here are the general charging parameters for 12.8V and 25.6V Volthium batteries:

Charging with the vehicle alternator
To protect your battery and alternator, adding a DC to DC voltage regulator between the alternator and the battery(ies) is highly recommended.

Storage
Before storing your batteries, refer to the technical data sheet of your battery (available on volthium.com). It is not necessary or recommended to connect the battery to a trickle charger.

Caution

  • When connecting batteries in series, never exceed 60V (four 12.8V batteries in series).
  • Do not connect a Volthium battery to batteries of different chemistry or to Volthium batteries of different voltage or capacity.
  • Do not use deep cycle batteries to start engines.
  • Always use a protection device (DC-to-DC) when an alternator is used to recharge the battery(ies).
  • Never store the battery when its state of charge is less than or equal to 10%.
  • Be sure to pre-charge the inverter DC input capacitors before connecting the lithium battery (unless the battery includes the Soft-Start function, available on some Volthium products).
  • Completely cycle the batteries (from 5% SOC to 100% SOC) at least twice a year to keep the cells balanced and healthy.
  • Do not immerse the battery in any liquid
  • Do not short-circuit the battery
  • Do not connect the battery with the polarity reversed
  • Do not expose the battery to temperatures above 60 degrees Celsius.
  • Do not drop the battery or apply excessive force to it.
  • Do not disassemble, puncture or modify the battery case.
