![]() So using diodes will virtual reduce the capacity of a battery by over 10%. And because the voltage towards the logger drops, the electronics need to draw at least 8.5% more current to compensate the voltage drop. So a single diode will dissipate 8.5% of the stored energy. A Shottky diode has a forward voltage of 0.3V, The nominal voltage of a SAFT LSH20 is but during data logger operation load the voltage drops to 3.5V. The common save way to put batteries in parallel is by using diodes, but they come with a price.Īlthough battery capacity is specified in mAh’s, it stores energy (mWh’s) and the diodes will dissipated a serious portion of this precious energy. If you put multiple Lithium batteries with all having the same state of charge in parallel, then it could work,īut using it like that is strictly discouraged by the battery manufacturer. Lithium batteries are having a high energy density and when used without caution, they can turn into dangerous devices. This is however something to consider with caution! Then you could consider the use of a lithium battery pack. ![]() If for obvious reasons a solar powered solution is not possible, 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,Īssuming the data logger can be mounted outside facing the sun. If you have an application requiring 1 or 2 remote data updates each day a single battery powered data logger can run for years. The ML-COVER-3LI is a power provision cover fitting our ML-417 off-grid 2G/3G/4G 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.Īlthough our off-grid data loggers are designed to be as low power as possible, running it from just one single Lithium battery,ĭue to the power demand of mobile communication, has its limits. ![]()
