Hello i will be storing my sailboat for 10 months and i have 4 Smart Lithium 200A, according to the documentation :
When leaving the system unattended for some time, make sure to either keep the batteries charged during that time or make sure the batteries are (almost) full and then disconnect the DC system from the battery.
And Victron also says: Low self-discharge rate The self-discharge rate has been significantly improved and is now a maximum of 2 % of the battery capacity per month .
So i understand i should store the Lithium at 100 %. Temperature is 30C year long. The batteries will be fully disconnected and they will discharge approximately 2 % per month so after 10 months they will stand at about 80 %.
Does anyone has a different experience or opinion ?
