Last month i was install macos on my laptop Lenovo Thinkpad T470S. My Laptop Specs:

RAM: 12 GB DDR4
1 x Synaptics SMBUS Trackpad + Trackpoint
1 x PS/2 Keyboard

Dual Battery

I have researched and learned that my Laptop has 2 batteries and I have learned a bit of ACPI code and patched SSDT-BATC. I use SSDT-BATC included with ECEnabler.kext and Battery works. everything works except battery

I thought everything was fine but no. I realized that my battery is only taking half its capacity. My battery as far as I know it has ~4k4 mAh but the macos side only receives ~2k mAh. I have searched and patched a lot but the number still only stops at 1k8. With such a battery capacity, I cannot use it without a charger. help me please. I spent a month trying to fix my battery but failed. if not fix my battery is too low and can not be used without charging 24/24. I can't watch youtube (1920x1080) more than 30p, only about ~30p my laptop is out of battery.... i also used kext CPUFriend + CPUFriendFriend (with 800mhz ) because i think its CPU problem but NOT... I'm really helpless right now. please help me...thank you very much

Here is my DSDT and SSDT i use for Battery ( work but with very small capacity )

i use SSDT-BATX.dsl without patch BAT0,1 to BATX because i just use it for fix battery 16,32 and 128 byte ( i dont use ECEnabler because its make my battery has been reported for maintenance - and still low capacity )
SSDT-BATC for Notify BAT0 and BAT1 ( i also have rename Patch )
SSDT-BATT.am. I found it on Oclittle github ( I don't know if it helpful or not )

And here is my EFI:
