This batter seems to have a PCB that prevents overcharging so you may be good
with any charger.
A good lead acid battery charger should have a cutoff at about 14.5 V,
which is good for 12.8V LiFePO4 battery. I found that some chargers actually
produce up to 18V but perhaps at a very low current.
A question: I have an automatic sealed battery charger for my 12V Pb-Ac
battery.

I recently purchased a 4 cell LiFePO4 12.8v 4.5ah battery. I fully charged
the battery to 14.4v and then hooked it up to my KX3. Total hours of run

the board has independent connections to each cell. It protects each cell
from over charge, over discharge, high current discharge, and short
circuit

batteries have a very good capacity to weight ratio, and they are safe,

John,
There are lots and lots and lots of web sites to buy both the batteries
and chargers. I normally buy my Hyperion batteries from allerc.com I
use them for my r/c planes. I use lipo's for my electric motors
(generating 2000 to 6000 watts depending on how big the plane is).
Anyways check

The ISOPower trickle charges the batteries. When mains power fails the ISOPower

Your thoughts?
