They have user replaceable batteries easily found at Walmart or Batteries + & great customer service if needed.
Has it's own separate monitor, which IMHO is mandatory not a cell phone app, that read pressures & temperatures constantly scrolling through all sensors.
After 6+ years of full-time use I replaced 6 of the 10 batteries.
Sold the system to a friend that used it another 2 years & replaced 2 batteries before selling his RV with the system included.
I do not work for TST nor do I get any compensation from them, but I do highly recommend this system & remember you get what you pay for.
