ISDT C4 EVO — Advanced Smart Charger & Battery Analyzer

The ISDT C4 EVO is an advanced universal smart charger and battery analyzer for cylindrical rechargeable batteries. Designed for users who want more than simple charging, the C4 EVO combines independent channel control, multiple operation modes, real-time battery monitoring and a clear IPS display in one compact and intelligent charging solution.

The charger features six independent charging channels, allowing each channel to operate separately with its own settings and working mode. The flexible slot design supports a wide range of rechargeable battery sizes, from common AA and AAA batteries up to large cylindrical cells such as 26700. Depending on the battery type and size, the C4 EVO can charge up to four cylindrical batteries at the same time.

The ISDT C4 EVO supports multiple battery chemistries, including Li-Ion, LiFe, LiHv, NiMH, NiZn and Eneloop batteries. This makes it suitable for many different applications, including RC accessories, transmitters, flashlights, tools, portable devices, household electronics and workshop use.

More than just a charger, the C4 EVO offers several professional battery management modes, including Charge, Discharge, Store, Destroy, Cycle, Activate and Analyze. These functions allow users to charge, maintain, test, recover and evaluate compatible rechargeable batteries with greater control and precision.

The built-in 320 x 240 IPS LCD display provides detailed real-time information during operation. Users can monitor battery type, charging or discharging status, charge percentage, charged capacity, charging time, internal resistance, temperature, voltage, current and capacity variation curves directly on the screen.

The C4 EVO uses a USB Type-C input with support for QC and PD fast charging protocols, with a maximum input power of 36W. It can also be powered from suitable USB sources, including a laptop USB port when lower input power is sufficient.

For safe and reliable operation, the charger features automatic charging parameter adjustment, reverse polarity protection, overheating protection and overcapacity protection. Internal temperature sensors help monitor operating conditions, while the improved quiet fan design reduces noise compared to the previous C4 generation. Gold-plated spring contacts further improve durability and service life.

Compact, intelligent and highly versatile, the ISDT C4 EVO is an excellent choice for users who need advanced charging, discharging and battery analysis functions for a wide range of cylindrical rechargeable batteries.
