What is your client's budget? Why is he replacing the GEL batteries? Is it as a result of performance? What kind of inverter is he using? Can the inverter handle LiFePO4 charging capability?Most importantly, what is his energy requirement because 8 units of 200ah battery on a 48volts system is 19200 watts.Even at 50%DOD on the GEL batteries that's still 9600watts .

Oga that inverter will soon packup because the charger is too small for that capacity. If his demand is within the 1.2kva requirement just get an external charger as an additional. Personally I don't think it's a good idea to get that much capacity for a 12v system but he has it anyway so that's the workaround

Nor be me go break hin heart.He got the batteries on awoof.May be I will advise him to incorporate panel solar charging.My calculation shows he needs like minimum 100amps to charge the 1000ah batteries.That itself is a challenge because of limitation in PVinput of 12v charge controller,mostly 720 watts.External charger is it then

I had to create another name to send this as I don't know what happened to my profile. I can't send messages on this thread but can on other threads.

A friend uses 6 units of 2v 1000ah battery he got from another friend( telecoms people) with his 1.2kva mercury inverter with 20amp charging current.He has utility for 12hours daily average but complains his battery's rarely gets fully charged.He doesn't have issues with performance though but is just worried thinking the partial state of charge can kill the batteries. Any advice on this? Should he incorporate external charging?
