I'm planning my first install on my boat soon. It will spend 6-9 months idle in European winter etc. Ive chosen the Electrodacus for my BMS. I am concerned that Daican doesnt not believe it harmful to keep the batteries at 100% over winter. There does not seem to be a easy way to get it to reduce to less than say 70%. Picking a lower highvoltage disconnect (eg 3.4V ? 3.3 ? ) doesnt seem that safe or accurate to pick a lower SoC setting. Ideally I'd like a 'storage mode' where it only charges if SoC is say 30% and stops at 70%. Its not easy or accurate I think to try and pick voltages for these SoC levels. From readings I've done I am of the belief that storage at 100% (and keeping it there every day all day) is not ideal, and can affect life span in cycles , and/or capacity. (Not disastrously, but enough to warrant not doing it).
An alternative is to switch over to some basic Lead Acids for winter storage and change my Victron Quattro profile to suit them, and disconnect the LiFePO4 , including the BMS.. That would also solve any possible low temp charging issues (which I can put thermistors into the SBMS0 of course).
