High-Capacity LiFePO4 Battery
12.8V 300Ah LiFePO4 High-Current Deep Cycle Battery
High-capacity LiFePO4 battery designed for RV, camper van, marine and deep-cycle applications requiring higher energy availability, longer operating time and high current capability. Final suitability should be confirmed against the charger profile, continuous and peak load, inverter requirements, installation space and operating conditions.
Product Features
High Energy Capacity
12.8V 300Ah provides 3.84kWh nominal energy for applications requiring longer operating time and higher energy availability.
High Current Capability
Supports 200A maximum charge current, 300A continuous discharge and 400A peak discharge for 10 seconds.
