Common FAQs
The battery is intended for restricted-depth RV, marine, 4WD, solar and off-grid systems. It provides 2.56kWh of rated energy and up to 150A continuous discharge. Confirm system voltage, load current, operating time, installation space, charger settings and cable protection before selection.
Start with 2.56kWh of rated energy, then apply usable depth of discharge, conversion losses, temperature, cable losses and reserve capacity. Divide usable watt-hours by the measured load in watts for an initial estimate rather than relying on Ah alone.
Confirm the published 650 × 400 × 61mm enclosure and 25kg weight, then allow clearance for terminals, cables, mounting, ventilation and service access. The supporting structure must safely carry the installed battery.
Replacement requires checking nominal voltage, charger profile, alternator or DC-DC charging, inverter settings, low-voltage protection, terminals, dimensions and maximum current. A similar physical shape does not confirm electrical compatibility.
Only when the model specification and BMS support the planned configuration. Use identical batteries with matched age and state of charge, equal cable paths and correctly sized protection. Confirm the maximum supported configuration before installation.
Use the charging, discharge and storage ranges published for the selected model. Charging below the minimum specified temperature is not supported unless the battery provides suitable low-temperature charging protection.
Compare the application load and surge current with the published 150A continuous-discharge limit and any model-specific peak limit. The BMS does not replace correctly sized cables, fuses or breakers and charger settings.
Documentation for UN38.3, CE, RoHS and applicable model certificates is available, with a 5-year warranty. Confirm destination-market requirements and provide the application, quantity and destination with the inquiry.
