Bluetooth Battery Monitor

Doubt after a couple of trips you’ll be monitoring all that often. I opted for a $42, 500 amp monitor for my 600AH of DIY Lithium batteries. Once the BMS stopped charging them I set the AH to 900AH... it keeps track of usage, %, charge/discharge amps, and voltage...all the info I need. Helped that the display was easy to locate in the BR.
