Frequently Asked Questions - B-Tec Lithium Enerdrive
What is the expected lifespan of the Enerdrive B-Tec Lithium battery?
The battery has a cycle life of over 3000 cycles at 80% depth of discharge (DOD), which translates to approximately 10-15 years of typical use.
Can I use this battery with my existing lead-acid charger?
It is recommended to use a lithium-compatible charger with the correct charging profile (14.4V absorption, 13.8V float). Using a lead-acid charger may damage the battery or reduce its lifespan.
How do I safely store the battery when not in use?
Store the battery in a cool, dry place at a temperature between 0°C and 45°C. Keep the state of charge at around 50% for long-term storage. Recharge every 6 months.
Is the battery waterproof?
The battery has an IP65 protection rating, meaning it is dust-tight and protected against water jets, but it is not designed for submersion.
How do I connect multiple batteries in parallel?
You can connect up to 4 units in parallel to increase capacity. Ensure all batteries are at the same state of charge before connecting. Use appropriately sized cables and fuses.
What is the maximum discharge current?
The maximum continuous discharge current is 100A. Short-term surges (up to 150A for a few seconds) are possible, but continuous high draw should not exceed the BMS limit.
Does the battery have a BMS (Battery Management System)?
Yes, the battery includes a built-in BMS that protects against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes.
Can I use this battery in series for a 24V or 48V system?
Yes, you can connect up to 4 batteries in series to achieve a 48V system. Ensure the BMS parameters are compatible for series operation.
What is the ideal charging voltage?
The recommended charging voltage is 14.4V for absorption and 13.8V for float. Do not exceed 14.6V to avoid damaging the BMS.
Does the battery require regular maintenance?
No, the battery is virtually maintenance-free. No water topping or equalization charging is needed. Simply keep the terminals clean and ensure proper ventilation.
