Statement regarding support for TLS Version 1.3 on R3.x Firmware

We want to inform you that CTEK does not support TLS version 1.3 on CHARGESTORM CONNECTED 1 and earlier models (Eva & CSR Series). This is due to the coding within Firmware R3.x We do however support TLS Version 1.3 in Firmware version R4.x

Please check your installed base before upgrading your security certificates to ensure continuity of the secured connection.  If this is not checked and firmware is not compatible, there is a risk connectivity could be lost.

For further information please check our Firmware Page 

Thank you in advance

Statement regarding support for CTEK CS ONE and Battery Sense apps on Android 13 OS 

Unfortunately, due to a change made by Google in the Android 13 Bluetooth Stack, many BLE (Bluetooth Low Energy) dependant devices (including CTEK) are now unable to pair with some manufacturer’s phones.

Please however, contact us at support@ctek.com where we will help try to troubleshoot the issues you are experiencing.
