Lithium battery and trickle charging
I replaced my 6v house batteries with one 12.8v 100ah deep cycle Lifepo4 battery.
Can I use a 12v acid battery trickle charger to keep the lithium battery charged?

When I replaced the 6v acid batteries with the lithium battery, I just swapped them out.
I hope that is all that is required.

Thanks

My understanding is that LiFePO4 batteries don't like to be trickle charged or float charged. And unless stored for very long periods, they don't need it. Unlike lead-acid batteries, lithium batteries have a very low self-discharge rate.

For example, I stored a pair of fully charged Lithionics 130 Ah batteries for more than six months in a climate-controlled (85° F) facility. When I checked them, one was at 92% and the other was at 99%.

In any case, I would not use a trickle charger designed for lead-acid batteries to charge lithium batteries, as its output voltage would likely be wrong for those batteries.

You'd better look at the settings of your converter and your solar charging controller (if any) and make sure they match what the TCBWorth battery wants to see.
