I just received my order of one 4.2v ECHO Manual Battery for 510/eGo and 25 HC Dual Coil Cartomizers XL for 510/eGo 2Ω, there is not contact between them but i can use those Cartos on my 900 ma batteries and i can use my regular ego/510 cartos on the 4.2 v batteries , do you have any solution for that ?
Thank you for your post here.
we did try Dual coil 2.0ohm on 4.2v echo batteries. some work very well. some work very poor. it happens because of the resistance of dual coil, which varies from 1.8ohm to 2.2ohm. if it is over 2.0ohm, it works well with echo batteries. if it is less than 2.0ohm, it does not work with echo batteries.
so my suggestion for you to try all of them and see whether you can find some resistance over 2.0ohm. if you find some, please use them on echo batteries. as for those less than 2.0ohm ones, please use them on your ego batteries.
if you choose a V V 650 batteries, you can use both of them with no problems, no matter which resistance it is.
hope my answer helps.
