Current Specs & Protection
Standard Charge Current 0.2C (0.06A) Standard Discharge Current 0.2C (0.06A)
Max. Continous Charge Current 1.0C (0.32A) Max. Continous Disharge Current 1.0C (0.32A)
Discharge Cut Off 2.2 V Energy 1.02 Wh
Configuration 1S1P Pcm/Wire Yes / Optional / Customized
NTC NO / Optional C-rate 1.0C
Self Discharge Rate ≤ 3%/month (at 25°C) Short Protection Yes
Overdischarge Detection Typical trip 2.0–2.5V (common options: 2.0V / 2.3V / 2.5V), delay 50–200ms, release 2.3–2.9V

PCM selection is based on the required continuous and peak/inrush current (OCP capability and delay). OVP/UVP thresholds are then confirmed for the selected PCM version. Our engineers will select and match the PCM to your specific requirements.
Overcharge Detection Typical trip 3.65–3.75V (common options: 3.65V / 3.70V / 3.75V), delay 50–200ms, release 3.45–3.60V.

PCM selection is based on the required continuous and peak/inrush current (OCP capability and delay). OVP/UVP thresholds are then confirmed for the selected PCM version. Our engineers will select and match the PCM to your specific requirements
Overcurrent Detection Multiple PCM versions are available for 1S LiFePO₄ packs (e.g., low-current 0.2A/0.5A/1A and high-current 2.5A/5A/7A/9A; OCP delay typically 9–15ms, PCM dependent).

Our engineers will match the PCM to your application based on your continuous and peak/inrush current requirements to ensure the pack meets your device requirements.
