Comprehensive High-Precision Battery Monitoring
The RECS module features a built-in 300A high-precision shunt that continuously monitors key parameters of RV batteries — including voltage, current, capacity, and temperature — delivering real-time accurate insights into battery status and remaining power. Even under variable conditions such as camping or long-distance travel, it ensures stable monitoring to prevent sudden power interruptions that could affect critical devices like refrigerators or air conditioners. This significantly enhances power safety and user confidence during trips.
Multi-Mode Communication and Remote Smart Management
The RECS module integrates Bluetooth, WiFi, and 4G wireless communication, alongside wired transmission via RS485/UART, adapting to diverse network environments including campsites, highways, and remote areas. This ensures users can monitor energy status anytime, anywhere. Using an efficient private communication protocol, it enables low-latency, high-reliability data transmission. Paired with a mobile app, it offers features such as power usage history tracking and remote alerts (e.g., low power, high/low voltage, extreme temperatures), delivering true “single-screen energy control and worry-free power usage.”
User-Friendly Design and Broad Compatibility
Designed specifically for RV users, the RECS module supports common battery types including lithium and lead-acid, with a voltage range of 8~120V and current range of 0~300A. Its intuitive app interface allows users without technical expertise to easily check remaining power and adjust usage plans in real time. It is particularly suitable for outdoor travelers seeking independent energy management, greatly enhancing the convenience and comfort of RV living.

FAQ:
(1) What is the purpose of a battery monitor?
Battery monitors can be used in any scenario involving battery packs. They continuously track the status of the battery pack and display key parameters such as remaining charge, current voltage, current, power, and other relevant data. This allows users to monitor battery health in real time, helping to protect the battery and extend its lifespan.
(2) What types of battery packs can the battery monitor be used for?
It is compatible with mainstream battery types on the market, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, sodium batteries, etc.
(3) What is the after-sales service like?
We provide a one-year warranty period. After one year, if the product is damaged due to its own quality issues, we will continue to offer repair or replacement services based on the specific circumstances. For cases where returns or exchanges are not possible due to reasons such as shipping costs, replacements will be sent with the next order.
