These is good news regarding the PIC18LF27J13. The PK3 mod suggested by Microchip support fixed the problem ID'ing the chip. Changed one resistor on the bottom and paralleled and one to the existing top one to lower its effective value.

Goofed on the 2nd charger board as explained in the previous post. the current resistor arrangement is now.

resistor pairs

1st	2nd	3rd	4th	5th
2.7K	2.2K	2.2K	3.3K	3.3K
2.7K	100R	2.2K	1K	1K

All battery+ connections have to go on the 3rd position.
The line sense needs to be on the 2nd position.
