Ok....the regular 510 model is not built for using LR Attys....they will kill it.....and it is a teasing, wierd acting slow death....
Have you already ordered replacements ? If you want to use LR attys you are going to need a 3.7
device to handle the load.
You "can" use the LR atty on an eGo type battery...but they aren't built to take it either....will shorten the overall life of the battery and could kill it at any given time.
Unfortunately...Looks like you need to order more supplies....sorry.. (hug) And if you stay with the regular 510 model...use regualr 510 attys...
