I have 5 808 Riva batteries that I am sending but I only have 1 charger. They are 750 mah batteries. If you can find a 901 charger at HC that will work with the 901 Riva or a 510 Riva charger, they are going to need it. They could use an 808-510 adapter to use a 510 charger.
I must have already given one of the chargers away
I do have a bunch of 808 cartos, empty and prefilled.
Also, I have some 510 cartos and I am guessing about 1000 - 1500 mls of asst juice between 18-36 mgs.
All good stuff and flavors that I have and would use myself.
Just trying to give you a heads up before you place your HC order
