Recently, a severe infringement and fraud issue has caught our attention. A FAKE application with a FAKE logo, a FAKE website https://www.voltalinkbatteryinvest.com/ and even FAKE videos under the name of voltalinkbatteryare now spreading all over India, attempting to seduce people to invest money in energy storage systems by using a FAKEvoltalinkbattery logo and real voltalinkbattery products photos.
It's obvious that they are looting money by using a FAKEvoltalinkbattery brand and have seriously violated the intellectual property rights of voltalinkbattery.
voltalinkbattery shall spare no efforts and no costs to go against the violation by all means legally before more people get deceived.
