If building your own pack I would highly recommend the overkillsolar BMS with bluetooth. This way you can easily check on the state of your battery with your smart phone or tablet. Also the Victron Smart Shunts are pretty expensive for what they do. I would recommend the AiLi current meter which is only $44 now on Amazon.

I can see all the information about the battery from the BMS app.
