Hi everyone, I have a new battery setup for when I go camping and fishing. I have gone from my old AGM to a 12v 120ah lithium in a battery box with a Victron 75/15 solar controller and a Victron smart shunt. It has been awesome through the summer and has handled all my power needs. Running fridges and camp lights with a 160watt solar panel charging through the long hot days.

Getting to the question coming into the winter months I will be storing the battery for 3 or 4 months. I have it at 50% soc but I'm wondering if I can leave the Victron smart shunt hooked up as it's connected to the battery directly. Will the milliamp draw be enough to drain the battery and do any damage?
Thanks

Spec is less than 1mA.

50% SoC, 60Ah/.001A = 60,000 hours.

So even if it's 10X published, you'd still have 250 days before it went flat.

I would be more concerned with the BMS draw. Worth checking voltage every 30 days just for giggles and/or following the battery manufacturer's storage recommendations.

Thanks sunshine _eggo
Unfortunately these Kings lithium batteries available in Australia give very little information, I have contacted directly but haven't received any reply. The only information is on the box they come in.
Thanks for the reply
