4 batteries

Hey all, I recently got a Snowwolf 365 and got 4 batteries at that time. 3 of them a E-SYB 18650 3.7V 3500mAh with a 30A discharge current, and one is an E-SYB 18650 3.7V 2800mAh with a 49A discharge current. My question is; is it safe to use all 4 together or would that damage my mod myself in...
