E&J Lithium 12,8V 100Ah 200A BMS with Heat and Bluetooth is the perfect choice for those who need a reliable and powerful LiFePO4 battery for motorhomes, caravans, holiday homes and other applications. With advanced technology and smart features, you get a safe and efficient energy supply for all your needs.
Powerful BMSThe battery is equipped with an active balancing BMS system that evenly distributes energy between cells during charging. This extends battery life and ensures optimal performance. The powerful BMS system has a capacity of 200A for continuous discharge and can handle a peak load of 450A. This means that the battery can deliver a constant power of up to 2560W,
Bluetooth – Överify the battery directly in the mobileKeep track of everything 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 lifeA 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 functionBefore 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 will the BMS be correctly calibrated, allowing the app to display the correct value.
Obs: At first start-up, the app may show low capacity and 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 coldThis 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 be used:Parallel connection:The battery can be connected in parallel. Charge the batteries separately and fully with an external charger, there may be a maximum difference of 0.2v between the batteries before parallel connection.
Generator useLithium batteries require several components. Use Victron DC-DC chargers or Wakespeed regulators to protect the generator, battery and optimize charging.
ChargersOnly 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 controllerVictron MPPT is recommended. If another regulator is used, make sure it can be set correctly for lithium.
How to store your lithium battery correctlyCharge to 100% before storage.Makes sure 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. Full not only means that the app shows 100%, but that all cells individually reach 3.6V. Depending on the charger and battery condition, this can take several hours. During this process, the battery may itself pause and resume charging until all cells are balanced. After charging is complete, it is recommended that the charger remains connected for at least 3 hours thereafter to allow time for balancing. Only after a full charge and balancing, the BMS will be correctly calibrated, allowing the app to display the correct value.
