LifePo4 Charge Performance
Thinking seriously about replacing our two GC2's with a pair of 100ah LifePo4's. Hearing a lot of chatter about how lithiums accept a charge much quicker than lead cells. Very familiar with how ou...

Trillium says:
"Note: Once a set of batteries have achieved a balanced condition, they should remain balanced through normal use
and charging. In order to keep batteries in balance and avoid over-discharge, ensure that batteries not in storage
receive a full charge weekly."
So that would apply to all LFPs I suppose? I am guessing they are worried about that business where the battery is "top balanced" so is vulnerable to going too low?
On the chargers not getting the bank to spec voltages, Trillium says that can lead to endless "cycling" and bad things wrt balancing. So might be a good idea to get the voltages set right, depending.
" Under many commonly-used lead-acid
profiles, the normal charge termination criteria will never be met, and the current will cycle indefinitely until the charger
is unplugged. Even after the charger is unplugged, the battery may not be ready for use until it is allowed to balance for
approximately 10 minutes. In the case of the 12.8V batteries, if there is a desire to use the batteries immediately after
unplugging the charger, the contactor can be manually closed using the status button on each battery"
