RS-COVER-3LI
Lithium battery power bank for off-grid data loggers
The RS-COVER-3LI is a power provision cover fitting our RS-525SE/PE off-grid cellular data loggers to power a data logger from up to 3 D-Size Lithium SAFT LSH20 batteries safely, with a combined lossless capacity of 39000mAh.
Although our off-grid data loggers are designed to be as low power as possible, running it from just one single Lithium battery, due to the power demand of mobile communication, has its limits. If you have an application requiring 1 or 2 remote data updates each day a single battery powered data logger can run for years. When you need multiple remote data updates each day, then our data logger with tiny integrated 1Wp solar panel has proven to be a very suitable solution, assuming the data logger can be mounted outside facing the sun. If for obvious reasons a solar powered solution is not possible, then you could consider the use of a lithium battery pack. This is however something to consider with caution!
Good to consider
Usage of lithium batteries for your data logger
Lithium batteries are having a high energy density and when used without caution, they can turn into dangerous devices. If you put multiple Lithium batteries with all having the same state of charge in parallel, then it could work, but using it like that is strictly discouraged by the battery manufacturer. The common save way to put batteries in parallel is by using diodes, but they come with a price. The nominal voltage of a SAFT LSH20 is 3.6V@2mA, but during data logger operation load the voltage drops to 3.5V. A Schottky diode has a forward voltage of 0.3V, so a single diode will dissipate 8.5% of the stored energy.
The RS-COVER-3LI has three D-size battery holders. You can choose the insert one, two or three Lithium batteries to reach a combined capacity of 39000mAh. When even more capacity is required, multiple boards can be arranged in parallel as well.
