The lanpwr battery also includes a Bluetooth 5.0 module for the support of real-time monitoring with a distance of up to 30 meters. Its transmission data delay is less than 200ms, and it can synchronously display 12 parameters such as voltage (accuracy ±0.1%), current (±1%), and SOC (±2%). The measured data of 2023 shows that it updates data packages every second (the lead-acid battery smart modules usually update every five seconds), and packet loss rate for the signal package in the test scenario of RV movement is 0.3% (normal industry standard for 2.1%). 10 levels of alarm thresholds on batteries can be set by the users through APP only. For instance, as soon as the SOC drops to 20%, the backup power source will automatically engage. This feature reduced the failure rate of the battery over-discharge of one particular European RV club by 89% in 2022.
Hardware cost analysis indicates that the Bluetooth module increases the unit price of lanpwr battery by 35 (which translates to 3.875 of the total price).
From the perspective of security mechanism, lanpwr battery uses AES-128 encrypted transmission and resisted 98.6% of wireless attacks in the 2023 DEF CON hacking conference test (the industry average protection rate was 83%). Its firmware OTA update function can support security patch push every month. For example, Q3 in 2022 increased the vulnerability risk of Bluetooth pairing threats CVE-2022-3812 (CVSS 7.5) to 0. Comparative testing indicates that the probability of data tampering of unencrypted lead-acid battery intelligent modules in proximity of 50 meters is 32%.
For environment adaptability, the connection between the lanpwr battery Bluetooth module is reliable between -30℃ and 70℃, and the bit error rate in transmission is less than 1E-6 (industry standard 1E-4). The 2024 Norwegian Arctic research station project proved that it was able to offer continuous communication for 72 hours at a low temperature of -45℃, with the signal strength ranging from -72dBm to -68dBm (the lead-acid battery Bluetooth module lost at -20℃). High-temperature test (60℃/85% RH) states that within 72 hours of uninterrupted work, the integrity rate of data packets is 99.97%, which is better than the MIL-STD-810G military standard’s requirement of 99%.
In real-world application cases, in 2023, Africa was able to save 78% of labor costs by reducing the frequency of on-site inspection by operation and maintenance personnel from three times a week to once a month through the off-grid medical vehicle project using lanpwr battery Bluetooth monitoring. Its historic data storage capability (up to 365 days of records) identifies a hidden voltage fluctuation of 0.05V in a specific battery pack, preventing an equipment loss of $12,000. Customization of 10 energy efficiency report templates by users is also supported, such as creating “Air Conditioning Load Proportion Analysis”. By instructing a specific RV club in how to properly allocate energy, average daily consumption of electricity decreased by 19%.
For compatibility, lanpwr battery Bluetooth is compatible with three operating systems: iOS/Android/Windows, and interfaces the apis of six energy management system giants such as SolarEdge and Victron. In actual world testing in 2024 when most devices were networked together (max units to network, up to 32 units), instruction response was under 500ms, and network success ratio was 100%. An Australian RV camping site has heightened its maintenance and operation efficiency by 640% by centrally checking 50 batteries. Fault locating time was reduced from 45 minutes to 7 minutes, and by $18,500 yearly on maintenance.
