GET TO KNOW YOUR BATTERY

Battery Management System

BATTERY SPECIFICATIONS

• Storing your Battery
  We strongly suggest your batteries are stored at room temperature, charged to between 30% to 50% of their capacity. We recommend that batteries be charged once every three months to prevent over discharge.

• Battery Performance
  Because Lithium Iron Phosphate batteries utilise a chemical reaction, battery performance will deteriorate over time even if stored for long periods without regular use.
  If the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened, or the device in which the battery is used may be damaged by electrolyte leakage.

• Battery Series and Parallel Mode
  12V batteries can be connected simultaneously with a maximum of four (4) in series OR (4) in parallel. 24V Drifts can be connected with a maximum two (2) in series or four (4) in parallel.

ALERTS AND WARNINGS

• Our JBD BMS contain a wide range of protective features, ensuring optimal charging and battery health throughout the lifecycle of the cells. Some of these protective features include;

Protective Alerts and Warnings

• Low Temperature Charging
  The battery has detected that you are trying to charge whilst the temperature is around 0°C. This warning is normal, and it is used to trigger the heating pads in your battery. Incoming charge current will heat the pads first, and then the battery will allow charge through when it reaches 5°C.

• High Temperature Discharging (OTD)
  The battery has detected that you are trying to discharge whilst the internal temperature is above 75°C. Discharging has been disabled until the temperature falls within an acceptable range.

• Low Temperature Discharging (UTD)
  The battery has detected that you are trying to discharge whilst the temperature is below -20°C. Discharging has been disabled.

• Pack Over-Voltage (POV)
  The total voltage of the pack has exceeded the maximum voltage. The BMS has turned off charging so that you do not overcharge the battery. Please discharge the battery.

• Pack Under-Voltage (PUV)
  The total voltage of the pack has reached the minimum allowed voltage. Discharge has been disabled. Please charge the battery.

• Short Circuit (SCD)
  A short circuit has been detected, and the BMS has protected you, and your battery. Please stop using the battery, and check your system thoroughly for anywhere a short circuit could have occurred. This could also be caused by an extremely large inverter charging its capacitors. If this is the case, disconnect the load and use a pre-charge resistor.

• Over Current Charging (OCC)
  You have exceeded the 200A charging limit. The BMS has disabled charging.

• Over Current Discharging (OCD)
  You have exceeded the 200A discharging limit. The BMS has disabled discharging.

• Cell Under-Voltage (CUV)
  A cell has hit the minimum voltage and the BMS has disabled discharging to protect the cell. Please charge the battery.

• High Temperature Charging (OTC)
  The battery has detected that you are trying to charge whilst the internal temperature is above 55°C. Charging has been disabled until the temperature falls within an acceptable range.

FREQUENTLY  ASKED QUESTIONS

• Can I series or parallel connect my batteries?
  Yes, you can connect up to 4 Fogstar Drift batteries in either series OR parallel – we’ve had our JBD BMS specially programmed to allow for this.

• What size terminals/posts are the Fogstar Drift Leisure batteries?
  The Fogstar Drift terminals are M8 in size. All of our Drift Leisure batteries come with bolts and terminal posts as standard.

• What are the charging parameters of the Drift batteries?

  • 12V = 14.2V Bulk/13.6V Float 24V = 28.4V Bulk/27.4V Float 48V = 57.6V Bulk/54.4V Float

• Could you tell me if your Fogstar Drift 12v leisure batteries are suitable for series connection at 24 or 48 volts please?
  Yes – we modified the JBD BMS at the manufacturing stage to add series or parallel support up to 4S and 4P. Units cannot be connected in series- parallel.

• Why does my Drift only show temperatures on three of the cells?
  It is perfectly normal for cell 4 not to be showing a temperature. Temp 1 is the BMS temperature, Temp 2 is ‘battery bank 1’ temperature, and Temp 3 is ‘battery bank 2’ temperature.

• What charger shall I use with my Drift PRO?
  The recommended charging current for a lithium leisure battery is typically around 20-30% of the battery’s capacity. For example, if the battery has a capacity of 200Ah, the recommended charging current would be around 40 amps. It’s important to check the specifications of your particular battery to ensure you are using the correct charging current.

• Can I lay my Drift on it’s side?
  Yes, your Drift battery can be lay on it’s side, in fact, you can lie a Drift battery in any configuration you wish. All we recommend is that you keep the terminals clear and clean.

• What is the maximum inverter size I can use with my Drift?
  The Drift 105Ah contains a 100A JBD BMS – this enables you to use your battery with inverters up to 1000W. The Drift 230/280/300/460/560 and 24V versions contain a 200A JBD BMS – this enables you to use your battery with inverters up to 2500W.

• How does the heater work in the batteries?
  The Drift heating pads are only activated when the battery is being charged, and are only powered by the incoming charge current, not the battery itself. If you put the battery on charge, it will heat the battery first, and then allow current through to the battery when the temperature is safe enough to do so.

• What settings do I use on my charger?
  Most chargers have profiles for various different battery parameters (Lead Acid/AGM), you should choose one that fits as close as possible to 14.2V-14.4V bulk and 13.5V-13.6V float.
  An acceptable charging range for the Drift batteries is 14.2V-14.6V bulk and 13.3-13.6V float.
  For Victron systems, please use a 14.2V bulk and 13.6V float.

• How can I store my battery when not in use?
  Charge the battery to 40-50% of its capacity: This will ensure that the battery has enough power to maintain its internal protection circuits.
  Store the battery in a cool, dry place: Avoid storing the battery in direct sunlight, extreme temperatures, or humid environments. An ideal storage temperature range is between 5°C and 15°C (41°F and 59°F).
  Disconnect the battery from any charging or load sources: This will prevent accidental discharge or damage to the battery.
  Clean the battery terminals: Wipe down the terminals with a clean, dry cloth to remove any dirt or corrosion. Use the bungs provided with the battery to prevent any damage to the terminals.
  Check the battery periodically: Every 3-6 months, check the battery’s voltage to ensure it remains within the recommended range. If the voltage drops below 12V, it’s advisable to recharge the battery to prevent damage.
  For extended storage (over 6 months): If you plan to store the battery for an extended period, it’s recommended to charge it to 50% of its capacity every 3 months to maintain its health.

• What settings do I use for my Victron equipment?
  First and foremost, it is important you consult your Victron Manual for specific set-up instructions. However we do have some settings to help you configure your equipment if using the ‘User Defined’ settings;

  • Absorption voltage:14.2V
  • Absorption time: The recommended setting is half an hour per 100ah of LiFePO4 battery (for example if you have x2 105ah batteries select 1 hour).
  • Float Voltage: 13.6V is acceptable for LiFePO4 batteries.
  • Equalisation vo ltage: 14.2V (you do not need to equalise Lithium, so you can turn this off, but in-case it ever runs a cycle the batteries will be ok at this voltage).
  • Temperature compensation: should be disabled on Lithium batteries.
  • Low Temperature cut-off: The Drift batteries have low temperature charging protection built into the battery. You can leave this off.
  • Discharge Floor: 0%
  • Tail Current: 4%
  • Peukert Exponent: Not required – this is for Lead Acid batteries.
