1 of 1 found this helpful Amazing little piece of tech, does everything it says it will , bought it for the AGM's in the dual battery system in my 4x4 . Voltmeter is as accurate as my mid range multimeter which is more than accurate enough for my purposes of needing to know when battery is at 50% . Better value than other products such as C tek battery sense , however does lack temperature function .
I've ordered another one to fit to the cranking battery and will see if its possible to monitor both batteries individually from the same app . Will post update once i know .
