DESCRIPTION
Enerdrive B-TEC 400Ah Slim Metal Case Lithium/LiFePO4 Battery
The new 400Ah ePOWER B-TEC Slimline lithium battery is designed and intended for use in deep cycle applications where a single battery is required that meets the amp hour capacity.
- Extremely compact size W 630 x H 498 x D 216.5 mm. All connection points for the battery are at one end including all Comms Ports and Reset Port.
- Reset button is not included on the battery itself, we have opted for a button that can be remotely mounted elsewhere in the install. This allows for a much easier restart process for customers and also keeps the battery more water tight with less chance of water ingress.
- Comms Ports are both RJ45 remote ports with CAN output. Both are reserved for future integration and functionality.
- Water resistant metal casing meeting IP52 rating and all external bolts and fittings are blind so limits the chance for water to travel from external to internal. Rubber style seals between all metal framing. Frames overlap as well to help avoid water ingress.
Smart Phone Monitoring System: The Enerdrive Enerdrive B-TEC Slimline battery incorporates wireless Battery Monitoring Technology. By downloading the Android™ or Apple® app to your smartphone or tablet device, you can monitor the following information; Battery Capacity; Battery Voltage; Battery Current (Amps); Battery State of Charge (SOC); Battery State of Health (SOH); Battery Status; Individual Cell Voltage; Battery Temperature; Battery Cycles; Battery Alarms & Battery Event Information.
Battery Management System: The battery is also equipped with an internal Battery Management System that can monitor and optimise each Prismatic cell within the battery during normal operation. It will protect the battery pack from over charge, over discharge, over temperature & short circuit. The BMS helps to ensure safe and accurate operation of the battery.
Size & Weight Savings: Lithium v AGM Capacities;
- 300Ah Lithium = 480Ah AGM
(Based on standard depth of discharge for both Lithium (80%) and AGM (50%).
The 400Ah Slimline battery is able to accept a maximum inverter capacity of 3000W only. Exceeding the maximum inverter capacity can damage the BMS Management within the battery.
If you are requiring a battery system larger than Enerdrive B-TEC battery, please look at the Enerdrive Pro Series Power Pack Systems which can offer multiple parallel and series connections with Active Cell Balancing Protection across the entire pack.
Please note B-TEC batteries must not be installed –
- In vehicle engine bays or in high heat environments, refer to Section 10 – Battery Specifications of the manual.
- In wet areas such as caravan chassis mounts, open ute trays or boat deck areas.
- Inside compartments dedicated to carrying gas.
This product is not suitable to mount anywhere with a possibility of being exposed to the elements. It is an electronic product designed for internal use ONLY.

| Charge Cycles Disclaimer |
The information provided regarding the life cycles of Enerdrive | Dometic lithium batteries is based on laboratory testing conducted under controlled conditions. These tests were carried out at a consistent temperature of 25°C, with discharge and charge rates set at 1C (1 x Capacity of battery). Under these specific conditions, it has been calculated that our lithium batteries can achieve over 2500 cycles with approximately 80% of original capacity remaining. However, it’s essential to note that actual performance may vary depending on various factors, including but not limited to, installation environment, temperature fluctuations, and variations in discharge and charge rates. It is recommended to avoid excessive discharges and charge cycles and to maintain a discharge and charge rate around 0.5C (0.5 x Capacity of battery) for optimal battery longevity. Doing so may result in a significantly higher cycle count. Please be aware that the numbers provided are based on cell-level testing and may not directly reflect the performance of your specific battery installation. As such, we advise users to consider their individual circumstances when assessing the expected lifespan of their batteries. Even in the scenario of reaching 2500 cycles, it’s important to understand that the lifespan of the batteries can extend beyond this figure. For instance, if batteries were fully discharged daily, a lifespan of over 6.8 years could still be expected. If you don’t normally take the battery under normal use below 30% SOC, then you could find that the battery will continue to meet your needs for many cycles to come. For further guidance on maximising the performance and longevity of Enerdrive | Dometic lithium batteries, please consult our technical support team or refer to the user manual. |
