This is the new battery I bought https://www.amazon.com/dp/B08TMRMTX8/ref=cm_sw_r_cp_apa_glt_fabc_V5CWAQ1PFE0FZ02SXA9K and also this one https://www.amazon.com/dp/B08K8HWHCR/ref=cm_sw_r_cp_apa_glt_fabc_980G3TK2PSHMEY35M0Q5. You think that they are compatible with the other 7? The original ones are FST 18650 2500mAh 3.6v/4.2v 9.00Wh. I am afraid of mixing the wrong batteries together and blowing the whole thing!
