Dang it. What are the disadvantages with this battery? Anything other than increased risk of explosion?
Is this the reason that I get the "Low Power" message when the battery is less than 40% charged?
You need to pay close attention to
battery specifications, primarily the
"amp rating", or
"maximum continuous discharge rate". The vast majority of vaping batteries need to have a 15 - 30 amp continuous discharge rate.
Your Lg battery likely has only a 4 - 6 amp cdr. Should you attempt to use it in a vaping battery device, you'll get "low power" even when the battery is fully charged. It doesn't have a high enough amp or current rating.
When choosing the best battery for your regulated battery device, choose one which will accomodate the wattage setting that you typically use:
