If you have a battery monitor then the INA219 current sensor can be quite accurate piggy backed on top of the BMS shunt to monitor current in/out of the battery bank. . Also, JLCPCB.com do quite a few sensors now as surface mount components, get them to solder a complete board up with sensors attached probably cheaper than buying the individual senors off ebay.
