Battery or board short?

[yair27]

Hello all...i have a wired problem....i have MacBook Air "Core i5" 1.4 11" (Early 2014)
The problem is when i login in(after password) the mac shutdown at the middle of loading..but if the charger is in its o.k....i was replaced a new battery but the same...i was also reset SMC and the same...even when i do internet recovery after downloading the os and loading to get to recoverymode its shut down....any idea? No critical history(liquid or something like that..)
Thanks!

I guess the battery charging circuit no longer recognises the battery properly, causing misread data and unexpected shutdown. (The circuit might think the battery is very small despite the battery itself has large capacity)
