Have 12 new batteries (4-2s,4-3s,2-4s and 2-6s) all have been discharged, balanced, charged twice back to storage (nothing better to do being locked down) and are in storage mode (3.8v) at the moment.

Anyways, things are opening up with the (covis-10 lock down here) and plan on possibly running boats this weekend. I have 2 chargers so it takes time to charge them all up. Wondering how far in advance can you charge the batteries up without any problems?

Been doing a search on this but must be using wrong wordage of what I'm looking for.

Thanks for any info and your input,

John
