The only thing is if you need to do your charger but I believe you can just get a tamiya to deans adaptor and just attach that to your charger and should be good to go.
If you really need it I'm sure you can borrow one from someone you know. An electronics expert or electrician maybe?
EDIT: Also you're probably never going to see the inside of your gun if you don't want to. For upgrades just contact a local gundoc and get them to do the work for you or attend a gundoc workshop and leave with the confidence to be able to do basic airsoft maintenance/upgrades.
I could probably pick up tamiya to deans adapter at home hardware or a computer store? hey dont computers have them?
