The 300A rating covers start-up surges from inverters, motors and compressors for up to 10 seconds only; any load that lasts longer must stay at or below 150A per battery. Set the inverter's low-voltage shutdown above 41.6V so the inverter stops before the BMS disconnects the battery.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow long will it run my loads?\u003c\/summary\u003e\n\u003cp\u003eEpoch plans runtime on 80% of the 6,400Wh nominal energy, about 5,120Wh per battery. Runtime in hours is roughly 5,120Wh divided by the load in watts: about 10.2 hours at 500W, 5.1 hours at 1,000W, 1.7 hours at 3,000W and 1.0 hour at 5,000W. These are DC estimates at 25°C on a new, fully charged battery; inverter losses, cabling, temperature, battery age and duty cycle change real results. For a parallel bank, multiply by the number of batteries.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan it charge in freezing weather?\u003c\/summary\u003e\n\u003cp\u003eYes, with a charger connected. When the cells reach 0°C (32°F), the BMS stops charging and uses the incoming charge current to power the internal heater; charging resumes automatically when the cells reach 5°C (41°F). The heater runs only while a charger is connected and supplying at least 0.5A, and it never uses the battery's stored energy. Solar charging stops at night, so on solar alone the heater runs only while the panels are producing. Charging is rated from -30°C to 55°C (-22°F to 131°F) with internal heating, and discharging from -20°C to 55°C (-4°F to 131°F).\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this battery waterproof?\u003c\/summary\u003e\n\u003cp\u003eNo. This model is IP54 rated, meaning it is dust-protected and splash-resistant. It should not be submerged, pressure washed, or installed where standing water can collect around the case or terminals. Install it upright in a dry, ventilated, protected location, and keep the caps fitted on unused data ports.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat charger settings should I use?\u003c\/summary\u003e\n\u003cp\u003eProgram every charging source for 48V LiFePO4: bulk\/absorption 56.8V to 57.6V, float 54.0V to 55.2V or off, equalization disabled and temperature compensation at 0 mV\/°C, and never program a charge voltage above 57.6V. The recommended charge current is up to 62.5A, and combined current from all sources must not exceed 150A per battery. Suitable sources include 48V LiFePO4 chargers such as the Epoch 48V 15A Lithium Battery Charger, solar charge controllers with a programmable or LiFePO4 profile, DC-to-DC chargers, and converters or inverter chargers that can be set to these values.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use it in a golf cart?\u003c\/summary\u003e\n\u003cp\u003eYes, where the motor controller's battery current stays within 150A continuous for one battery, and acceleration and hill-climbing peaks stay within 300A for no more than 10 seconds. It is a deep-cycle battery, not a cranking battery. Secure it upright against vibration and protect it from water spray, because IP54 is splash-resistant, not waterproof. Charge it with a 48V LiFePO4 charger, and confirm that the 25.2 × 9.65 × 8.66 in, 110 lb case fits the cart.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eEpoch Batteries Limited Warranty\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWarranty Period\u003c\/strong\u003e\u003cbr\u003e\n11-year limited manufacturer warranty\u003cbr\u003eYears 1–3: free replacement against qualifying defects in materials and workmanship\u003cbr\u003eYears 4–11: 40% off MSRP on a replacement battery\u003cbr\u003eRegister within 90 days or keep your proof of purchase\u003cbr\u003eBatteries left uncharged for more than three months are excluded from warranty coverage\u003c\/p\u003e\n\n\u003cp\u003eEpoch Batteries-branded products are covered against qualifying defects in materials and workmanship for the applicable warranty period, subject to Epoch's model-specific remedy schedule and the terms of its warranty policy.
