PS4 controller battery mod (LIPO safe ?)

[dragoss91]

Hello there ,

Recently I got a PS4 console and noticed the controller's battery is draining so quick . I saw some people made battery mods with 2000mah batteries so I bought one too .

The problem is I bought a 2200mah Li-Polymer battery and I know LiPo batteries get's damaged if they discharge under 3.0v . Does anyone know at what voltage the PS4 controller starts to send Low Battery notifications ?

Also , do you think is safe what I've done ? The battery came with a circuit and I guess it's for preventing overcharge .
