Product Description

Product Description

Cold-Climate Deep Cycle Power

12V 100Ah Low-Temperature Sodium-Ion Deep Cycle Battery

1200Wh auxiliary energy solution designed for winter RVs, cold-weather marine systems, remote cabins and off-grid solar applications.

Product Overview

The Chalongfly 12V 100Ah sodium-ion deep cycle battery is developed for auxiliary energy systems operating in cold climates and demanding outdoor environments.

With 1200Wh of nominal energy and an operating temperature range extending down to −40°C, the battery is particularly suitable for winter RVs, camper vans, marine house-power systems, remote cabins and cold-region solar installations.

The battery provides 100A continuous discharge, up to 200A peak discharge, smart BMS protection and optional Bluetooth battery monitoring for convenient system management.

Frequently Asked Questions

Can this battery operate at −40°C?

The battery is designed for operation down to −40°C. Actual capacity and power performance depend on temperature, state of charge and system conditions.

Is this an engine starter battery?

No. This page is primarily positioned for deep-cycle auxiliary energy. Engine-starting applications require a separately engineered high-cranking-current battery.

How much energy does the battery provide?

The 12V 100Ah configuration provides 1200Wh of nominal energy.

Can it power an inverter?

Yes. Inverter power and surge current must remain within the battery's 100A continuous and 200A peak discharge limits.

Can it replace an AGM RV battery?

A replacement solution can be developed after checking voltage, capacity, charging profile, maximum load, dimensions and terminal configuration.

Is Bluetooth monitoring available?

Yes. Bluetooth monitoring can provide battery voltage, state of charge, current, temperature and operating-status information through a compatible mobile application.
