I forgot to say that i measured the baterries on PEBO rescue device, there are 4 batteries , 3 are in referent values from12.2V - 13.1V, but 1 was 9.7 V. so i replaced that one and had lift working for one week.
But after one week the lift stoped with same error "batlowPEBO", so i measured the new battery i replaced a week ago, and the result was 10.1 V i think the issue is with battery charging.
