1 kWh (1 battery) net!, 2 kWh capacity (2 batteries) or 4 kWh (4 batteries) or 8 kWh (8 batteries). An average sloop up to 7 meters uses up to 1 kWh up to 7 kilometers per hour. Many people sail up to 30 kilometers per day and then 4 kWh is sufficient.
can be used for 12 volt, 24 volt and 48 volt motors
From the top brand GreenCell.
Semi-traction VRLA AGM lead acid batteries.
V alve Regulated L ead A cid (VRLA) technology: a lead acid battery regulated by an invisible pressure relief valve. Only as a result of incorrect charging and/or defective cells will gas escape via a safety valve.
A maintenance free battery and uses the advanced Absorbent Glass Mat technology (AGM). This technology ensures that the battery acid is absorbed into the glass fiber mats and no longer floats around loose in the battery. This prevents sloshing, leaking and the formation of oxyhydrogen.
So it can be used without any problems in normally ventilated areas. The battery is therefore safer and can be used in almost any position (except upside down) to be mounted .
The Absorbent Glass Mat also promotes the life of the battery during deep discharge because the plates cannot warp. This makes an AGM battery good suitable for deep discharge / deep cycle (up to 80%) and cyclic use. AGM batteries for cyclic use are specially designed for many times intensive discharging and recharging. This makes these AGM batteries optimally suited for applications such as maintenance battery, service battery, solar panel battery, boat battery, caravan battery, camper battery, mobility scooter battery.
The AGM battery can deliver a very high current for a short period of time and also deliver power for a long period of time. This makes the product ideal for starting the engine and also for electric winches and bow thrusters. AGM batteries are more suitable for delivering high current for a short period of time compared to Gel batteries.
The indicated capacity is at a discharge time of 10 hours. If you discharge the battery in 5 hours, the capacity decreases by approximately 15%, see table below for Constant Power Discharge Characteristics.
As for the lifespan, you can discharge up to 400 times, which is more than enough for average sailing behavior. And that even with all discharges up to 80%! If you discharge up to 50%, you can even discharge the battery 800 times. If you discharge up to 30%, you can discharge no less than 1,500 times.
With a float voltage, an AGM battery will still have 80% of its original capacity after 6 years at an average ambient temperature of 25 ºC.
A lifepo4 lithium battery lasts up to 8 times longer: after 3000 cycles at 80% discharge, it remains at 80% capacity.
Operating and storage temperature: -20°C to 60°C. At an ambient temperature of 20 degrees, an AGM battery delivers the best performance. For example, AGM batteries retain a capacity of 40% at -20°C. Not only cold temperatures have negative effects on the lifespan of the AGM battery, this also applies to very high temperatures. According to the design standards, a Long Life AGM battery has a functional lifespan of 10 years at an ambient temperature of 20°C. At a temperature of 30°C this will be 4 years and at 40°C 2 years. It is optimal if batteries are used in rooms where the temperature is regulated, so that the AGM batteries perform optimally.

Including battery charger
Maintain the batteries with a trickle charge voltage of approximately 13.2 Volts (at 12 Volts and 26.4 Volts at 24 Volts and 52.8 Volts at 48 Volts) and a periodic refresher charge (source: Victron, Electricity on Board). With float voltage, an AGM battery will still have 80% of its original capacity after 6 years at an average ambient temperature of 25 ºC.
- If you choose a 12 or 24 volt system, you will receive the Victron Blue Smart IP65 Battery Charger with mobile app.
  - Splash and dust resistant
  - Seven-step intelligent charging algorithm
  - Recovery of deeply discharged 'dead' batteries
  - Automatic power supply function
  - Automatic compensation at high or low temperatures
  - Several other properties that increase longevity
    extend the battery life
  - Low power mode for charging smaller batteries
  - Li-ion battery mode
  - Setup and configure, read voltage and current
    using Bluetooth Smart mobile app.
  - You can also use the charger as a power supply when connected directly to the engine (for example in combination with a generator).
  - 5 year warranty.
  - Brochure.
  - Manual .
- At 48 Volt: including waterproof 48 Volt 20 Ampere charger. IP67: completely dustproof and waterproof up to 1 meter depth. Charging time rounded 800 W per hour (with 85% efficiency) = rounded 4 hours and for the last 20% (=1 kW) 4 hours. So a maximum of 8 hours.
  - Can be charged via connection to a regular socket (Schuko connection).
  - The battery charger charges in 5 phases for the longest possible battery life.
  - The battery charger has a soft start function to protect the batteries when starting charging.
  - The battery charger is high frequency: maximum energy saving, longer battery life, reduced battery heating, low weight and limited size.
  - The charger has a capacity of up to 11.5 kW.
  - The charger can also charge GEL, lead acid and Lithium batteries.
  - The battery charger is shockproof.
  - Minimum charging temperature: 0°C and maximum charging temperature: 50°C.
  - With temperature sensor, this regulates the charging voltage.
  - The electrochemical activity in a battery increases or decreases as the ambient temperature changes. The charging voltage must be reduced as the temperature rises to prevent overcharging. The opposite is true at very low temperatures; the charging voltage must then be increased to prevent undercharging. Temperature compensation is required when the battery temperature is expected to be lower than 10°C or higher than 30°C for a longer period of time: temperatures common for boat applications. The recommended temperature compensation is -20 mV/°C for float use (stand by) and -30 mV/°C (calculated from 25°C) for cycle use (cyclic use) for each individual 12V battery). So at 0°C: 25*+20mV= +0.5Volt. So despite the low self-discharge at 0°C it is important to keep the charging voltage at the right level. At 100% the charging voltage drops to 12.2 Volt: the level of 40% discharge and that is not good for the battery.
    The maximum charging voltage of the batteries is 14.6 Volt to 14.8 Volt in cycle use at 12 Volt (13.6 Volt to 13.8 Volt in float use).
  - With charge indicator that can be read remotely.
  - A 160Ah battery is charged in approximately 8 hours with this charger, a 200Ah battery in approximately 10 hours and a 240Ah battery in approximately 12 hours.
including Victon battery monitor with display showing the remaining battery percentage and current consumption.
You will then see how long you can still sail.
With battery monitoring: the display also gives an acoustic message if the battery percentage is too low (20%). Minimum voltage at 20% charge = 11.6 Volt per battery (23.2 Volt for 2 batteries = 24 Volt and 46.4 Volt for 4 batteries = 48 Volt).
