The 8A-8S is a high-current battery spot welder designed for assembling lithium battery packs with up to 8 series cells. It delivers strong, stable welding current and precise control for reliable and efficient battery pack production.
High-efficiency transformer & low-impedance MOS
MCU-driven auto-balancing with manual override.
Low-voltage cutoff & per-string overcurrent fuses.
Supports cascading for $>24$ series packs.
Li-ion/LiFePO4/LTO (Best for $<50$AH).
Auto / Manual (with timer).
Fully symmetrical isolated design.
Auto-stop on low energy to prevent power loss.
