Battery Issue, doesn't charge, dc-in becomes hot

done SMC and NVPram resets no change, the dc-in heats up and the battery doesnt charge. What other possible parts could it be if the battery doesnt charge but is detected? could it be a faulty dc-in?

the kernel can run on low cpu if i have it in the smc reset mode (when the fan noise is spinning i presume and the charger light is off)

Could be battery, DC in or logic board (charging IC circuit, or something else). The kernel task CPU is high, are the fans spinning loudly?

^ yes, thats due to running in SMC mode or whatever so its not actually running through the battery, during that stage the cpu load on the kernel is low ~ 5%. Battery replacement is probably what i'm truly after hopefully.
