Endurance Lithium 12V 200Ah Heat-Bluetooth is made for use in motorhomes, caravans, boats, electric vehicles, holiday homes etc. For both industrial and commercial use. The battery has an advanced built-in battery management system (BMS). The BMS protects against short circuits, high temperature overcharging and shuts down the battery if something unforeseen happens. Endurance Heat has a built-in heating foil and can be charged in sub-zero temperatures. The heat is automatically activated when the battery is charged below 0 degrees and turns off again when the right temperature is reached. The heating foil only works when charging, the foil never takes power from the battery. The built-in BMS control manages the heat in the battery and starts the heat when needed. The battery has built-in Bluetooth, which gives you full access to important data from your mobile phone or tablet.

LifePO4 has twice the utilization rate, weighs less and requires less space than conventional batteries. Lithium is capable of delivering extremely high currents and a fully discharged battery can theoretically reach full charge in less than an hour. - Battery Management System (BMS) - Lithium LifePO4 technology - Leak proof and maintenance free - Deep discharge safe (DIN 43539TS) - Doubled utilization rate - UL, CE, VdS approved - Approved according to IATA/ICAO Voltage: 12,8Volt Capacity: 200AH Max charge current: 160A Recommended charge current: 60A Recommended charge voltage: 14,6V - 0,2V Recommended maintenance charge (Float): 13.8 - 0.2V Max consumption: 200A 350A/3s Max output W: 2560W Cycles: 100% discharged: about 2000 Temperature short-term -20 60. Temperature long term -10 30. Recommended storage temperature: 15 to 40 degrees Note: The battery can be connected in series or parallel but a maximum of 4 can be used. Charge the batteries separately and fully with an external charger before series and parallel connection. In case of series and parallel connection, Bluetooth will not work. If the battery needs to be stored for a long time, the battery should be fully charged and then discharged to about 50%. The battery needs at least one charge and discharge every six months. Generator Lithium batteries can have a higher charging voltage, which places demands on the other components of the boat that are connected. For example, there may be surge protectors, electrical wiring, electronic equipment and chargers that need to be adapted. Because lithium batteries have a different charging cycle, the generator may also need to be protected or replaced. For example, we recommend a Victron DC-DC or a Wakespeed regulator between the alternator and the battery to optimize charging and protect the alternator. Battery charger The battery charger should be adapted for lithium batteries. For optimal life and performance, you should follow the recommended instructions. If the charger has multi-stage charging, check that there are no Desulphation or Equalize charge stages where the charger periodically charges with voltage up to 15-16V. Solar controller. The regulator should be adapted for lithium, we recommend Victron MPPT for optimized charging and easy setting. If the regulator lacks settings for Lithium batteries, it should only be used if it can be set/programmed to the recommended value. We always recommend changing to a regulator adapted for lithium.
