# Kikusui PFX2731S Battery Testing System NEW
**Features:**
Enables high-rate charge/discharge tests necessary for enhanced rapid charge/discharge performance.
The PFX2731S is a 6 V-20 A 6-channel battery tester that supports high-rate charge/discharge tests. It is operated with the application software BPChecker4000, which is exclusive to the PFX2731S. As one PC can operate up to 4 units (24 channels), one can construct a multi-channel charge/discharge system according to the required number of channels.
In order to safely conduct long-term continuous testing, it also has 2-system independent protection functions for hardware and software, as well as various protection functions such as a connection confirmation function that detects incorrect wiring and integrated capacity protection.
- 10 ms continuous measurement (at the fastest setting)
- Supports single cell evaluation (C-rate can be set)
- Various charge/discharge modes (9 modes in total)
- Charging: CC, CC-CV, CP, CP-CV
- Discharging: CC, CC-CV, CP, CP-CV
- Pattern charge/discharge (CC(+CV), CP(+CV))
- When an error is found, a built-in path switch immediately terminates the test.
- Four thermostatic chambers (produced by Espec) can be operated synchronously
- A T-type thermocouple (optional) can be used to measure temperature.
- The system can be set up by connecting a LAN cable.
- Enhanced protection functions
### System Configuration
#### Example of PFX2731S x 1 unit connected with LAN cable
The PFX2731S combines a control unit, a measurement unit, and a 6-channel 6 V-20 A charge/discharge unit into a single housing, allowing the creation of a compact charge/discharge system with up to 24 channels. Continuous data recording of 10 ms is possible for all channels due to the complete isolation and independent measurement functions of each channel.
