HIGH VOLTAGE · 125–182V
StackLine HV — module to 1000 V system
StackLine HV is the high-voltage branch of our LIC hybrid supercapacitor module family: 125.4–182.4 V per module, and eight modules in series reach a 1000 V-class DC system. Fused busbars, a CAN node on every module and 3 mm forced-air ducting between cells come built in — series voltage climbs without the integration risk doing the same.
At a glance
Four numbers carry the family
Forty-eight 3.8 V cells; a 33S build gives 125.4 V for lower buses.
Cells C/ESR sorted to a ±5% window before the string is welded.
Insulation proof level every module passes before it leaves the line.
Forced-air option keeps tall strings inside thermal margins.

Cabinet arrays
Cascade to 1000 V without reinventing the rack
Series strings raise voltage faster than they should raise risk, so each StackLine HV module carries its own FUSE and its own CAN node: the controller sees every cell, and a faulted module isolates instead of propagating. Tall forced-air builds keep 3 mm ducts between cells; insulation is proven at AC 2000 V for one minute, and storage spans −40 … +80 °C with 0–35 °C recommended.
This is the same architecture class the grid side already trusts — a 5 MW supercapacitor BESS has run in commercial operation since 2023. For UPS bridge tiers, genset-start support and transit power, the ladder is the same: LIC responds in 1–50 ms while slower assets wake up behind it. And because large-cell ESR sits as low as 0.47 mΩ (DC), the surge current still lands inside the first half-cycle — your fuse plan coordinates the event instead of compensating for it.
