About ANCEL BM300 Bluetooth Voltmeter for All 12 Volts Solar Power Systems/RVs/Motorcycles with Automotive Charging Cranking System Test
Overall Feedback:
91% positive
83% praised for its accurate readings, but 17% found inconsistencies.
I compared the battery monitor with a Fluke CNX 3000 and found it to be accurate, with a difference of only 0.01 volts.
The device has weak/little bluetooth to an Apple 14 Pro Max and provides random information.
83% liked that it's powered by batteries or usb, but 17% found the batteries drained quickly.
I used the battery tester to determine that the battery was not always charging when I thought it should be, and made circuit changes to solve the problem.
The Bluetooth range is pretty good, but it has a noticeable impact on my phone's battery. However, limiting the app's run time takes care of that.
87% appreciated its compatibility with multiple battery types
This device does not require pairing like a typical Bluetooth device.
82% liked the clear and bright display
I found Bluetooth connection to be the best option as I didn't want to run wires and penetrate the camper for an inside display.
I can instantly know the status of my battery by opening the app on my phone.
91% praised for its rugged design, while 9% experienced durability issues.
Once my battery starts to show weakness, I can charge it overnight and it will be good to go for 6 months to a year before I need to charge it again.
The 12V accessory battery is crucial for the proper functioning of the vehicle and any strange behaviors can be traced back to a defective or dying battery.
