I have a simple question that I want to verify. Just purchased a Lithium starting battery for my boat and also purchased the 500amp Smart Shunt. The question is, should the cable coming from my outboard be connected to the load side? I assume the answer is yes, I checked the CCA requirement for my motor and it's only 400amps. Thanks in advance
If you are intending to count the energy from the outboard alternator for this battery, then yes, you need to connect it like that.
400A should be fine for a 500A shunt, besides, it is a really short burst for starting.
As wkirby mentioned, yes.
Our Canter based motorhome has a 500A SmartShunt monitoring all current through our 4 cell 300Ah LiFePO4 including the 3.9l TD starting current that has recorded a peak of 730A but only for a fraction of a second.
Your outboard start current will be a breeze for your SmartShunt.
