Hi,

[top]

After charging overnight per the A123 manual and holding at 14.4V with a be

nch supply, the batteries now appear to be OK. I ran a UPS cycle loaded at=
1A 230V (230W) and it ran through the 5 minute discharge OK with the batte=
ries dropping from 14 to 12.5V. The QUINT-UPS by Phoenix Contact has a des=
ign issue though, it only charges the LiFePO4 batteries to 13.5V per batter=
y (27V total), when according to the A123 ALM12V7 manual float charge shoul=
d be 13.8V per (27.6V total) and hold for 14.4V for 4 hours or 28.8V. It d=
oes not do that so I=92ll check with Phoenix Contact and see if they know a=
nything otherwise I=92ll have to modify the circuitry. The float voltage i=
s even a bit too low to get a full SOC on the lead acid batteries I bought =
(they like 27.6V float, 27V gets them about =BE charged and takes a longer =
time to get there, about 8 hours instead of 1 hour.)
