Epoch 70.4V (72V) 105Ah Golf Cart Battery Complete Kit - Lithium (LiFePO4)

Key Features

• Single-Unit Bank Replacement: Replaces an entire traditional 6-battery 72V lead-acid bank with a single 132 lb unit, drastically reducing total weight and eliminating inter-battery series jumper cables.
• High-Output Performance: Delivers 70.4V nominal voltage (55.0V–79.2V operating range) and 105Ah capacity for 7.39 kWh (7,392 Wh) of stored energy.
• High Current Capacity: Supports a continuous discharge of 250 Amps, with peak discharge ratings of 500 Amps (for up to 15 seconds) and 1,000 Amps (for up to 2 seconds), plus 100A–105A continuous charge capability (500A peak for up to 15 seconds for regenerative braking).
• Safe & Durable LiFePO4 Chemistry: Built with a 22S1P prismatic Lithium Iron Phosphate cell configuration rated for 3,500+ charge cycles and backed by an 11-year manufacturer warranty.
• Rugged IP67 Enclosure: Housed in a corrosion-resistant stainless steel case (21.7" L x 13.4" W x 9.9" H) rated IP67 against dust and temporary water immersion (up to 1 meter for 30 minutes).
• Comprehensive BMS Protection: Integrated smart Battery Management System with automatic cell balancing safeguards against over-voltage (79.2V cutoff), under-voltage (55.0V cutoff), overcurrent, short circuits, and extreme temperatures (charging from 32°F to 131°F; discharging from 14°F to 131°F).
• Bluetooth & Digital Diagnostics: Features an included dash-mount digital Bluetooth battery gauge and pairs with the Epoch Li-Ion app (iOS and Android) for real-time monitoring and over-the-air (OTA) firmware updates.
• Scalable Capacity: Supports parallel connections of up to two batteries for an expanded 210Ah (14.78 kWh) bank (series connections are not supported).
• Zero-Maintenance Operation: Eliminates watering, acid spills, and equalization charges while maintaining a low 3% monthly self-discharge rate.

Kit Components

• Epoch 70.4V (72V) 105Ah LiMAX Battery: A 132 lb (60 kg), 70.4V nominal LiFePO4 battery housed in a stainless steel enclosure with integrated on/off switch, communication port, vent, and M8 female terminals.
• 72V 15A Onboard Lithium Charger: Matched smart charger (~7-hour full charge time from empty) programmed specifically for the 22S LiFePO4 profile (78.1V–79.2V bulk/absorption).
• Digital Bluetooth Battery Gauge: A dash-mountable digital display providing real-time State of Charge (0–100% SOC), voltage, current, and system status at a glance.
• 72V-to-12V Step-Down Converter: Converts high-voltage pack input to a regulated 12V-class output to safely power auxiliary 12V accessories, lighting, and electronics.
• Remote Power Switch Harness: A remote on/off power switch with wiring harness for convenient dashboard system control.
• Mounting Considerations: Due to its 132 lb mass and 21.7" x 13.4" footprint, this kit requires upright installation secured with hold-down hardware rated for 132 lbs (mounting brackets and main DC fuse/breaker not included).
