Frequently Asked Questions
What is the difference between the continuous and peak discharge ratings?
The battery is rated for 400A continuous discharge and 800A peak discharge. The peak rating applies to brief demands rather than sustained draw.
What does the 6S1P configuration mean?
It identifies a configuration of six cells in series and one parallel string.
Which connector does this battery use?
It uses a pair of 3-hole aluminum blocks. Check that your planned connections suit this terminal type.
How much space should I allow for installation?
Compare the listed dimensions—14.2'' × 10.1'' × 9.3'' or 360 × 255 × 235 mm—with the available space in your installation area.
What temperature range applies during charging and discharging?
Charging is specified from 0°C to 45°C. Discharging is specified from -20°C to 55°C.
