Features & Protection Systems

Built-in Battery Management System (BMS): The integrated BMS provides comprehensive protection including over-charge protection, over-discharge protection, over-current protection, short circuit protection, and high/low temperature protection. The BMS monitors individual cell voltages and temperatures to ensure safe operation.

Self-Heating System: The battery includes an internal self-heating element that enables charging in temperatures below 0°C (32°F). The heating system activates automatically when charging is attempted in cold conditions, allowing the battery to charge safely down to -20°C (-4°F) discharge temperature.

Bluetooth Monitoring: The battery includes built-in Bluetooth connectivity compatible with iOS and Android devices. The monitoring app displays real-time voltage, current, state of charge, cycle count, individual cell voltages, and temperature data.

IP67 Waterproof Rating: The battery case is rated IP67 for protection against dust ingress and temporary water immersion (up to 1 meter depth for 30 minutes), making it suitable for marine and outdoor applications per manufacturer specifications.

Connection Capabilities

• Series Connections: Max (1) in series
• Parallel Connections: Max (4) in parallel, Plug & Play configuration
• Maximum Bank Configuration: Up to 4 batteries in parallel for 400Ah total capacity at 38.4V nominal

Applications

According to manufacturer documentation, this 38.4V 100Ah battery is designed for the following applications:

• Golf Carts: 36-volt golf cart systems (verify compatibility with your specific golf cart model and year - consult golf cart manufacturer for voltage requirements)
• Marine Trolling Motors: 36-volt trolling motor systems with continuous draw up to 120A (verify amp draw compatibility with trolling motor specifications)
• RV Systems: 36-volt RV electrical systems and house battery banks
• Solar Energy Storage: Off-grid 36-volt solar battery banks for residential or commercial applications
• Marine Applications: 36-volt marine electrical systems with IP67 protection requirements

Important: Verify compatibility with your specific equipment before purchase. This battery operates at 38.4V nominal (30V-43.8V range), which is compatible with systems designed for 36V nominal voltage. Contact your equipment manufacturer to confirm voltage requirements and electrical specifications match this battery's output range.

Charging Settings

To properly charge this Epoch B36100A battery, verify that your charging equipment (battery charger, converter, inverter charger, solar charge controller, or DC-to-DC charger) can be programmed for the following manufacturer-specified parameters:

Important: Not all chargers support multi-stage charging or programmable settings. If your charger does not have programmable settings, verify it can be set to the Bulk/Absorption voltage range (42.6V - 43.2V) and disable float, equalization, and temperature compensation if those options are available. Consult your charger's manual or contact the charger manufacturer for programming instructions specific to lithium batteries.
