Im going to try to make a t-beam clone on Rak wisblock architecture because they offer quite a few other chips that could give the device extra functionality, like cameras, motion detectors, rfid readers, and infrared sensors, etc...
Question for you - if I wanted to back a bunch of batteries into my wisblock repeater system, I want to use rechargeable 18650's, do I need them to be in series or in parallel?
You would want wire them parallel the output would remain the same. My other solar node has three 18650s wired in parallel and it has running now for 21 days with no solar input. Oh and the batteries are measuring about 55% of their capacity.
@innercityprepper @RavenwoodAcres I built a solar node with a large solar panel and 4 x 18650. The node was just sat on the ground whilst testing and fell over and the battery went flat. However the node didn't recover charge wise until I removed 3 of the batteries. I'm not 100% sure but I think the RAK units struggles to get the voltage up over 4 batteries. I've been running a solar light node with a RAK board and 18650 and it's run fine for a month and hasn't dropped below 80%. Does the RAK solar enclosure supply enough power to run a node?

The difference is crazy !
On a single 18650 battery the LilyGo lasts about a day and the WisBlock lasts a week !!!
I totally agree, these enclosures are very well designed, built and documented.
I wonder how much effect on SWR any magnets would have if mounted to the bottom of the Unify enclosure.
Good question, I should connect it to my Nano VNA and do some testing.
None. A stationary magnetic field will not affect this.
@@TonyLing True, but the metal in the near field will.
I've ordered a bme680 to monitor weather telemetry!!

Any links to the clones that are as good?
Can a tiny solar panel like that recharge a 2000mAh battery?
In my experience, only in perfect conditions. For example, sunny days with 4 to 5 hours of exposure.
Want help with Wisblock gps tracker

@@RavenwoodAcresperfect, thank you!
@@innercityprepperyou NEED a battery BMS if you use multiple cells, or you need Protected cells!!! Very important. Google “18650 protected”

@@RobCanada can you find documentation on that max input of the solar charge controller built into the board?
