E&J Lithium Battery 12,8V 300Ah Heat – Bluetooth Powerful. Smart. Reliable
E&J 12,8V 180Ah Heat is the modern choice for those who want to replace traditional AGM, lead-acid or GEL batteries with something more efficient and future-proof. With built-in Bluetooth, heating function and intelligent BMS, you'll have a stable and secure power supply for your car;the mobile and stationary applications – perfect for motorhomes, caravans, boats, solar installations and more.
Bluetooth – Överify the battery directly in the mobile
Håll keep track ofEverything from voltage to cell status in real time via the EJBMS PRO app, available in both the App Store and Google Play. The battery has built-in Bluetooth, giving you full visibility of battery health and performance directly on your smartphone or tablet.
Active balancing for longer life
A built-in automatic balancing function ensures that all cells in the battery have the same voltage level. The function is activated at the end of the charging process and ensures smooth operation and optimal capacity over time, without compromising performance.
Calibration of BMS – for correct data and function
Before first use and after extended storage, it is important to calibrate the battery's BMS (Battery Management System). Follow these steps:
Fully charge the battery before use and leave the charger on for approximately 3-4 hours after full charge. During this process, the battery may occasionally pause and resume charging until all cells are balanced. Only after a full charge and balancing, the BMS will be correctly calibrated, resulting in the app showing the correct value. Obs: At first start-up the app may show low ågåterståend capacity – this is completely normal. The battery is supplied at 30% capacity and is not deeply discharged. After longer storage, for example in winter, the BMS must be recalibrated. In motorhomes and caravans, there are small, continuous power drains that can discharge the battery over time without being detected. This can mean that the app shows, for example, 80%, even if the battery is discharged. In this case, repeat the section Calibration of the BMS.
Heat function – Charging even in cold
This battery is equipped with an automatic heating function that is activated when the temperature drops below 0°C and a charger is connected. The heating will continue until the battery cells reach 5°C, after which charging will start. The heating takes place without affecting the discharge and is driven by the charging current but not by the battery's own capacity.Obs: A charging current of at least 12A is required for the heating to work properly. The battery is optimized for operation even at temperatures down to -20°C.

To consider when installing
Serial connection:
The battery can be connected in series up to 4 pcs. Charge each battery separately and fully before connecting in series. There is a maximum difference of 0.2V between the batteries when connecting.
Generator use:
Lithium batteries require raw components. Use Victron DC-DC charger or Wakespeed regulator to protect the generator, battery and optimize charging.
Chargers:
Only chargers suitable for lithium batteries should be used. Make sure that the charger does not have functions such as Desulfation or Equalize Charge that can raise the voltage to 15 or 16V, which can damage the battery. Additional charging voltage: 14.2 – 14.6 V.
Solar cell controller:
Victron MPPT is recommended. If another regulator is used, make sure it can be set correctly for lithium.
How to store your lithium battery correctly
Charge to 100% before storage:
Sure that the cells are balanced and charged for less downtime.
Discharge to 80%:
Reduces stress on cells during storage.
Disconnect the battery completely:
Use a battery disconnector or disconnect the negative terminal. Some systems draw power even when the main power switch is off.
Charge after three months:
Charge to 100%, then discharge to 80% for continued proper storage.
Charging after winter storage:
Fully charge the battery before use and leave the charger on for about 3-4 hours after full charge. During this process, the battery may occasionally pause and resume charging until all cells are balanced. Only after a full charge and balancing will the BMS be correctly calibrated, allowing the app to display the correct value.
