If you are using this with a lithium battery which has a BMS that field tells you how much overshoot there was when the battery reaches full charge and the BMS shuts off. There is energy stored in coils on the output of most charge controllers and it has to go somewhere. That shows up as a voltage spike on the output. My battery is 12 volts and right now it is showing a spike of 19.78 volts. This can blow up boards that are not protected such as a fridge board in an RV. The problem is on the same page and is labeled Energy. There is both in and out and normally they should be almost the same. Instead the energy out is almost twice the energy in. That is not possible. This battery cannot generate more than you put in. ### 3/5 — Decent *2023-09-30, version 1.2.0* Bluetooth range is short, probably a shortcoming of the device and not the app specifically. I wish the data ranges were more configurable. I’d like to be able to see “last hour”, “last day”, etc. instead of just “now” and “last 7 days”. 7 days is too much data to represent accurately on a phone screen. It would also help if I could download the data to csv for analysis on a computer. ### 5/5 — We’ll done! *2023-07-20, version 1.1.5* Thank you for producing a good app that works with good hardware. ### 5/5 — Very good product *2023-06-28, version 1.1.3* App works VERY good and haven’t had any issues with the hardware. Bluetooth works better than other Bluetooth shunts I have tried ### 1/5 — TBD shunt::: stop working after 2 months *2022-02-10, version 1.0.3* Does not read amps or watts anymore and voltage is all over the place… ## Frequently asked questions about FE ### What is FE-Shunt?
