Hi all. 

Just a quick question. 

Can anyone supply the correct settings - charging voltage , floating , charging Amps ect ,

for 4 x of these batteries on a Kodak OGX5.4 and watchpower ? 

The batteries spec sheet only shows charging voltage of 14.6v , 58.4 seems excessive high value 24/7.

Thanks , JP 

With a nominal voltage of 12.8V*4=51.2V this is the same as a 16S lithium battery which usually floats at 53.5V-54V.

Do this look ok ? 

adjusted floating voltage to 54

After a 2hr 20 min loadshedding the bank charged for about 36 minutes.

That is quite possible depending on how much load you had during LS. To be honest it is difficult to tell the state of charge of lithium from the voltage alone, usually it is easier to tell by lights on the battery or connection to the BMS to read the SOC directly.

Do you have a time set for the bulk charge? For my 100A lithium battery I have the bulk charging time set to 120min (setting 32) so that the voltage stays high for long enough for cells to balance and charge the battery fully before it  goes to float. As there is a BMS in the battery one would expect it to prevent any overcharging, but there is no information I can find on how the BMS operates and how to tell if it is at 100%SOC.

If I was running these batteries I would set the bulk charge to 57V for 120mins, float at 54V and see how it goes from there.

P.S. I see in your image that  float is set to 53V.

@Slowtoker as side note, if not already part of your setup, consider using a 48V balancer to ensure the 12V batteries in the long run stay balanced.
