Battery Tester EBCA20 (UK Plug) A compact, precise battery test and charge discharge controller in an aluminum alloy housing. The EBCA20 offers accurate voltage, current, capacity, power, and energy measurements with flexible modes for capacity testing, power simulation, and controlled recharging. Portable and durable for field use, bench testing, and routine battery maintenance. Key benefits Accurate measurement and four wire detection for reliable results: separate voltage and current wiring reduces measurement error. Flexible test modes: constant current discharge, constant power discharge, and constant current constant voltage charging for lithium and lead acid batteries. Automatic cycle support: run automated recharge then discharge cycles for capacity verification and endurance testing. PC connectivity and control: Mini USB to TTL serial interface for curve plotting, calibration, firmware updates, and automated test sequences. Portable and robust: aluminum alloy enclosure, compact size and light weight for transport and repeated use.
