Common FAQs
The model is intended for higher-capacity RV, marine house-bank, solar and off-grid systems. Confirm system voltage, load current, required operating time, charger profile, installation space and environmental conditions before selection. Rated energy is 1.92kWh, but actual runtime depends on the complete load and system efficiency.
Start with 1.92kWh of rated energy, then apply the selected depth of discharge, inverter or conversion losses, temperature effects, cable losses and reserve capacity. Divide usable watt-hours by the measured load in watts for an initial estimate rather than using Ah alone.
Use a charger compatible with the model's published voltage range. The technical table lists 29/30A standard, 72.5/75A recommended and 145/150A maximum charging current. Confirm charging voltage and current before installation.
The model publishes up to 145/150A continuous discharge and 1.28/1.92kW continuous power. Check inverter efficiency, surge current, cable size, fuse or breaker rating and BMS limits. Do not size the load from Ah capacity alone.
Replacement requires checking nominal voltage, charger profile, alternator or DC-DC charging, inverter settings, low-voltage protection, terminals, physical dimensions and maximum current. A similar case size does not confirm electrical compatibility.
Only when the selected model and BMS support the planned configuration. Use identical batteries with matched age and state of charge, equal cable paths and correctly sized protection. Confirm maximum series or parallel quantity before installation.
The published charging range is 0°C to 50°C and discharge range is -20°C to 60°C. The enclosure is rated IP65. IP65 does not permit continuous submersion, and charging below 0°C is not supported without suitable low-temperature protection.
Documentation for UN38.3, CE, RoHS and FCC review is available, with a 5-year warranty. Confirm destination-market requirements and provide the application, quantity, charging system, installation environment and destination with the inquiry.
