Product Components
BattLink
One BattLink can monitor the voltage, internal resistance and negative pole temperature of a single battery to provide continuous 24/7 monitoring of your battery infrastructure.
SensorLink
One module with an additional CT per battery string will intelligently analyze thermal runaway trends and effectively produce alarms for battery thermal runaway.
CurrentLink
One module with an additional CT per battery string will monitor the charge/discharge current and ambient temperature of a string.
Nexus
It can manage up to six groups of batteries, each group has a maximum of 300, and the total number is up to 960, with display and buttons.
Battery Health Indicators
The SensorLink module monitors a variety of battery health indicators of a given battery string and reports back to the Nexus module. When combined with the other modules of the battery monitoring system, it ensures uptime with 24/7 monitoring of batteries in all applications.

| Power Input | 10.8～13.8VDC input, powered by control module or externally. |
| Communication Port | UART port, dual-channel, internal parallel connection, connecting to the Nexus control module. |
| Float Current 1 & Ambient Temperature Port | Connect to the float current transformer through the float current test cable and monitor 1 float current. The test cable has 2 environmental temperature monitoring probes. |
| Float Current 2 Port | Connect to the float current transformer through the float current test cable and monitor 1 float current. |
| Float Current 3 Port | Connect to the float current transformer through the float current test cable and monitor 1 float current. |
| Indicator Lights | There is a two-color indicator light that indicates four things based on the below presentation. GREEN LIGHT ON: The module is powered on.GREEN LIGHT FLASHES ONCE: There is a module hardware fault/an abnormal internal resistance test.RED LIGHT ON: The internal resistance is normal.RED LIGHT FLASHES ONCE: The communication is normal. |
