Hello all i need help with something, I bought my dad some Halo batteries a couple of months ago and we were using the tanks that Halo sells but we started having issues with the wicks and switched him over to the Kanger T3 vgo threaded tanks but now no place sells the replacement heads for them so what i need to know is can someone recommend another type of vgo threaded tank that will work on the Halo's (going back to the Halo tanks is not an option). I did switch him to some ego batteries and was able to buy the t3s tanks so it's not like he is going without I just don't want the Halo batteries to be useless.
