Rechargeable batteries are used for projects using solar and/or wind charging systems. EPIC's Polar Group has used SunXtender AGM batteries by Concord succesfully for many deployments. These batteries, aside from being reliable, offer several advantages. They are sealed and non-spillable, which makes then safer and easier to handle in the field; they have a low self discharge rate, which is important for a low power system, with extended periods of time between charges (arctic conditions); and they are exempt of DOT HazMat requirements (49 CFR Section 173.159) provided that they are shipped in their original package or in a package that satisfies the requirements of 49 CFR 173.159(d).

The August 16th, 2018 edition of Socorro's El Defensor Chieftain featured a cover story describing the EarthScope/EPIC located at New Mexico Tech. Reporter John Larson's piece says "Tucked away on a hilltop in the backyard of Tech’s campus is the Incorporated Research Institutions for Seismology Portable Array Seismic Studies of the Continental Lithosphere Instrument Center – EarthScope/EPIC for short – the largest facility of its kind in the world. 

All-In-One systems combine seismic sensors with their dataloggers in a single, easily-deployed unit. Because these units do not require numerous cables to connect a sensor to its datalogger, they avoid many serious problems associated with cables, such as incorrect connector types, broken and chewed wires, or damaged pins. They are also much easier to deploy than conventional sensor/datalogger combinations. Their use can dramatically cut down on both station installation times and the number of required personnel. Their smaller size can also be very beneficial for deployments using volume-limited transportation methods, such as sea vessels.

Because Nodes and SmartSolos both utilize lithium batteries that operate above the 100Wh threshold, shipping of more than 2 units produced by either vendor will require special handling, including: packing, marking and documentation. Special handling, if needed, will require the assistance of a certified dangerous goods shipper.
