I want to use the COM.LTE module in our camper. We are using LiFePO4 batteries with a maximum charging voltage of 14.6 V.

Is it ok to use the module with an input voltage of about 15 V? The JW5033H step down converter can handle voltages up to 18 V so I think it should be ok? I've tried it also for a short time and it worked.

I'm asking because the m5stack docs are saying: Please strictly follow the input range (5-12V) to prevent damage...

Thanks,
Roger
