I have the Skylla IP44 connected to lithium batteries, and have customized the charging profile accordingly. To avoid unnecessary cycling of the battery, how do I disable the Skylla from "refreshing" the battery every week? This weekly refresh is great for flooded batteries, but is completely unneeded and even detrimental for lithium. Yet, it is still included in the lithium CC/CV mode. Can this be disabled?
Hi @SolarSean
if a weekly hour long absorption is bad for the battery, the absorption voltage is set too high.
for most LiFe(Y)PO4 batteries, a weekly 'absorption' phase is needed to keep the cells balanced.
Thank you for the reply, but a lithium battery does not require weekly absorption when in storage. Are you stating that Victron lithium batteries require a weekly absorption cycle? If that is the case, how do Victron's cells become unbalanced when there aren't any loads draining the battery?
