I am trying to upgrade from 144v (24) cell lead acid to (45) LiFePO4 batteries.
I am struggling to understand how to set new perimeters.
I found this on-line. These are the adjustment ports but I don't know what battery pack they are adjusting for.

Hope you can help me with settings for my pack.
Learning from your knowledge would be greatly appreciated.
Hoping it is this simple.

Looks like my situation is less complicated because I am working with like voltage packs. (both 144v)
LiFePO4 cell voltage is 3.2 and max is 3.65. (3.65 is max for top balancing)
You like 3.35 max volts per any one cell in the pack for safety and longevity.

I am looking at data sheets and my NG3 (144v) float lead acid at 159.4volts. (I have seen this on lead acid fully charged)
Math: 159.4 divided by 3.35 equals 47.56 cell. If increased my total cell count from 45 up to 48;
that would be right in the safety zone of it being theoretically impossible to overcharge a pack of balanced cells,
If that is correct I can move on to the next challenge of reduced amperage @ 80%.

Is my approach correct?

Sounds good, thanks.

Lithium chargers, I have seen on line, have the same red, yellow, green indicators.
But, I could not find their value. A yellow on my charger means the
pack has reached 80% state of charge and the output amperage is reduced from 11 to 8.3
80% of 159v is 127v Charger reduces to 8.3amps at 127v. (about a 25% reduction in amps)
Anyone know what the parameters are for a lithium charger on yellow?

I could top balance, drive the car and then charge while monitoring both the pack voltage and charger amp output.
Adjust to what, I don't know? How, I don't know? Just asking am I on the right path with my thinking?
If I am lucky and things are close enough, I have nothing to adjust.

I am going to put a BMS on the pack but the chip shortage is effecting production. Not good!!
