Compact power, ready off the shelf.
Eight standard 18650 soft packs, 7.2 V to 14.4 V — assembled and tested in Taiwan.
Protection
Small packs, serious safeguards.
- Voltage: OVP and UVP on every cell group — over- and under-voltage both cut before damage, not after. (OVP limit · UVP cutoff · cell voltage · clamped · held at the limit · discharge)
- Current: OCD and OCC protection, with a fuse backstop on B-series and 3S/4S models for a second, independent line of defence. (fuse · 2nd protection · 3 A max discharge · load current · overcurrent · 0 A held)
- Temperature: OTC and OTD windows on AT/BT models — charge is blocked outside 0–50 °C class limits, discharge cuts on overheat. (50 °C · charge cutoff · re-enable threshold · pack temperature · charge current · charge cut · charge resumes · 0 A)
- Cell balance: Advanced balancing keeps every group level, so packs stay healthy across the full cycle life. (bleed resistor · every group level · 4S · 14.4 V)

Shared electrical limits
One electrical spec across all eight models.
The detail ▾
All eight models use Li-Ion 18650 cells: 3.35 Ah typical / 3.25 Ah minimum capacity (0.2C), max discharge 3 A, charge window 5–40 °C, discharge window −10–55 °C.Where the cells come from
Cells from Japan, Korea and Taiwan.
The detail ▾
Cells are sourced from Japan, Korea and Taiwan and are compliant with UL1642 / PSE / CB / UN38.3. Every pack is assembled and tested in Taiwan with 100% cell screening.Different shape or connector?
Dimensions, connectors and labels are specifiable.
The detail ▾
Dimensions exclude cables and can be changed according to requirement. Connector WST/P3-I20004 or equivalent; wire harness UL1430 (AWG24); pin-out P+ (red) / NTC 10 kΩ (yellow) / P− (black). Label print is specifiable.Which pack fits your device?
