Looks very similar to mine which is a Tire Minder aka Minder Research system
The sensors with Lion replaceable batteries
Tire Minder gives you free batteries, every year, for 7 years. So i simply ever year removed the transmitters when the rig was stored for winter and got new batteries and new O rings. My system was about 4 years old and the thing went crazy alarms and no signal so i gave up on it. Later just to see what would happen decided to contact Minder Research via email.

1st response "we will give you a small discount on a new system"
after a few more emails asking why would I consider buying this @#$%$# again when it dies so quickly. For $300 +++ it should be operational for many years

2nd response - So sorry to hear you have had issues please send the system to us and let us look it over. OK Why not my cost in shipping less than $5.00 so sent it off to Florida.

Two weeks later after a few probing questions I get a USPS tracking # and a message saying we found your monitor to be defective and new version is on it's way to you. A week or more goes by and a package arrives. A few days later I installed the system and found it works like a champ all at a cost of only $5.00.

They are good well intentioned folks however the made in China stuff is what it is ...

Never had any issues with the transmitter caps cracking - do not over tighten them they are cheap plastic nothing more - get the O ring to seal finger tight and you should be good to go

They are the same unit, just sold under a different name. There are several others out there that are the same units with different names.

After the first cap cracked, I have only gone finger tight on the cap and then only touched the neraled edge just below the plastic cap on the body of the sensor to tighten the unit onto the valve stem.

They still crack. I think I have now replaced all the original sensors, the new ones seem to be ok, I hope.
