the other device fulfils more of my requirements, but still very interesting, i hadn't heard of lora before
SinoTrack ST-925L is 20,000mAh build in battery for long lasting operations. Can buy from AliBaba SinoTrack online store.
@Rodney Yeo If possible can you share the battery life from your test and specify which working mode it was based on?
I have not yet purchase SinoTrack ST-925L 20,000mAh tracker as it is under consideration at the moment due to the doubled priced of ST-904L tracker unit.
I have SinoTrack ST-904L 1,200mAh tracker which battery life lasted about 16 hours with Always ON mode as tested a verified 3 times already.
Thanks for sharing! If you need longer battery life, you can try the Mictrack MT700 (with a 7800mAh battery, lasting up to 2 weeks in Always ON Mode).
Why not using the free Lora network? SenseCap T1000A is the size of a credit card. Thickness 4 cards. I send every 5 min the location and after 5 days it lost 10% of the battery. So one month will do it easily.
