Pipeline Inspection Battery
Our Pipeline Inspection battery packs are ready for land, underwater and extreme environments
SWE designs battery packs and depassivation instrumentation for your unique inspection device on land or underwater.
Our battery solution for your sophisticated instrumentation and analysis devices is available in a wide range of electro-chemistries for extreme environments.
SWE Pipeline Inspection Gauge (PIG) battery solutions are based on a new line of quality Lithium Sulfuryl Chloride cells available from our cell partners.
C, D, & DD high rate, high capacity cells
High Voltage (3.91 V OCV and 3.5 V CCV typical per cell)
Higher capacity DD (up to 32 Ah) and up to 20% more watt hours
Broader operating temperature range (-20 °C cold temp to +100 °C high temp)
Shock and Vibration certified cells
Mechanical pack robustness via engineered pack design and polyurethane potting
Electrical pack robustness via quality tab welds, diodes, and connectors

Under Voltage Lock Out (UVLO) circuit
- Monitors the discharge voltage of the PIG battery pack.
- Cuts off and locks out the battery discharge from the tool to keep the battery pack voltage safe and above 2 V per cell.
- Recommended for battery pack when a low voltage cutoff is not already incorporated into the PIG tool.
Battery Pack Fuel Gauge
Tracks Ah consumed in the battery
Once removed from tool or before next tool run, reports capacity consumed
Allows more efficient utilization of the battery pack
Parallel string continuity testing confirms all strings are connected in the pack
