With just a push of a button, discharge begins, emitting a preliminary sound when reaching 180.0V, and stopping the discharge with a final sound when it drops to 168.0V. A long press will force an emergency stop. Discharge without recording is also possible. The cutoff voltage is accurately controlled by a microcontroller with 12-bit A/D conversion. Discharge results are recorded on an SD card, and the discharge capacity is automatically calculated using the included analysis software. There is also an option to set the discharge stop voltage in 1V increments for research purposes (after stopping, it returns to the set value). It discharges at approximately 230V 20A, discharging the maximum load (4.7KW) of the "Hoba Battery" series. Due to its simple structure allowing high current flow, it can measure SOH and SOC accurately compared to conventional constant current discharge devices.

The measurement principle is the same as measuring the water volume by discharging after the dam is full. Regarding charging, even at the same full water level (voltage), the water retention varies depending on whether the water is poured in like a flood or gently. The charging system initially charges in bulk (8.4V-50A, CC charging) and then gently charges towards the end (CV charging), allowing for the rapid creation of fully charged batteries. At the end of the process, the microcontroller detects the drop in current and automatically terminates the charging, resulting in a consistent charging state. Discharge occurs with the same resistance body releasing the same power. A computer software is included that saves the voltage at every moment to an SD card and automatically calculates the total energy discharged during operation. The HK-LF85 is a model developed for used NISSAN LEAF batteries (LIB) with a capacity of 500Wh, capable of charging and discharging at a maximum of 50A, with a charging and discharging test for one module taking about 3 hours. Customization for other lithium batteries is also possible. (Patent application pending)

"Release Battery" is an easy-to-use and highly accurate battery tester designed for those involved in battery maintenance. It is a product equipped with a system that rapidly discharges deep cycle batteries (lead-acid batteries) from 12V to 48V down to the cutoff voltage (10.5V for 12V) in approximately 30 to 60 minutes, accurately measuring the capacity and saving the results to an SD card for reporting. Additionally, the R type can also be used as a high-current discharger (load device/load resistor) for solar power systems and Li-ion batteries. 【Features】 ■ Pressing the "START" button initiates discharge, displaying elapsed time and voltage on the screen every second, with data saved to the SD card. ■ Automatically stops discharging when the cutoff voltage is reached, which is gentle on the battery. ■ Simultaneously turns on the charging power supply when discharge stops, allowing for automatic charging (the discharge circuit is turned off. Optional). ★ Until August 31, 2019, inquiries mentioning "Ipros saw this" will receive a 【12% discount】 ★ *Demo units are available only from stock.
