E-Rickshaw Battery Load Tester 300A 12V
India's trusted 300A battery tester — diagnose weak 12V lead-acid batteries in under 15 seconds.
What Is the ERLT-300?
The ERLT-300 is a professional e-rickshaw battery load tester built for Indian workshop conditions. It applies a real 300A resistive load for 10–15 seconds to each 12V block in a 48V e-rickshaw pack (100–200 Ah) — accurately identifying weak batteries before they fail on the road. Also works as a car battery tester and inverter UPS tester. Also see: Car Battery Load Tester.
