I watch a video on youtube and the guy took the Evic apart and said it had three 1500MaH LiPo batteries. . Doing more research I came across a thread that said the guy was wrong and the batteries were Li-ion. Which is true? I am thinking of getting an Evic VT. Is it safe? Are there any accounts of the battery venting? I know it won't explode but it could start a fire while charging at night.
Does the Evic VT have a LiPo battery or is it a Li-ion?

Do not charge batteries while unattended.
We use different formulations of lithium batteries (Li-Ion) in our mods. ICR, IMR, and LiPo batteries are all lithium ion batteries.
Protected ICR batteries are considered to be obsolete for mod useage because of their volatile and explosive nature.
The internal non-removeable batteries in regulated box mods are often LiPo batteries (which are not safe chemistry). These have potential to flame up or possibly explode in thermal runaway. These can be used relatively safely in regulated mods due to their electronic protective circuitry which will kick in before a battery goes into thermal runaway.

The external removeable batteries are IMR (Li-Mn), or hybrid/IMR batteries (NCR or INR). These are safe chemistry batteries. They will not burst into flames or explode, but may still vent hot gas.
Battery Basics for Mods
Deeper Understanding of Mod Batteries
Common sense battery safety practices say don't charge any battery overnight without supervision. Electronic devices and their safety circuits can fail, and its not worth losing your home or life. Charge over a fire resistant surface such as a stove top, metal baking pan, or pyrex glass dish. Use only reputable brand name chargers (Xtar, Pila, Nitecore, Efest LUC) designed for lithium ion batteries.
IMHO, a box battery charger which charges external batteries (safe chemistry) is safer than using an USB charging port to charge internal batteries (not safe chemistry). Charging ports tend to wear down over time and the wiring may be subpar.

And again... NEVER EVER charge batteries unattended -- which means at night while you're sleeping. That would be akin to a pilot taking a nap during the most important and dangerous parts of the flight -- taking off and landing.
