Cameron Sino Battery for Velux KSX 100K 2000mAh 21.60Wh

  • Compatible with Velux KSX 100K and Integra Solar models
  • 2000mAh capacity delivers 21.60Wh of rechargeable power
  • Built-in protection against overcharge, over-discharge and short circuits

  • Dimensions 151.00 x 34.00 x 32.50mm fit original battery compartment

Direct Replacement for Velux KSX 100K

This lithium-ion pack replaces the original Velux 832817 and 865103 cells in KSX 100K solar roller shutters and Integra Solar window systems. It matches the factory voltage of 10.8 V and the 2000 mAh capacity so the smart-home controller sees an identical power source.

Upgrade From Depleted Original Cells

The jump is worth it when the original pack no longer holds enough charge to cycle the shutter through a full day or when the low-battery warning appears on the Velux control pad. A fresh 21.60 Wh unit restores the intended autonomy without firmware changes or adapter cables.

Capacity and Headroom

The 2000 mAh rating comfortably powers daily open-and-close cycles for solar-driven blinds under normal sunlight conditions. Extended overcast periods or very frequent actuations will drain the pack faster, so the system may request a recharge sooner than in peak summer.

Questions about this item

Will the 151.00 x 34.00 x 32.50 mm dimensions fit the Velux KSX 100K battery compartment?

The pack measures 151.00 x 34.00 x 32.50 mm and is built to the exact specifications of the original Velux 832817, 865103, GP2100AFHT and HHR-210AH cells for a direct fit.

How do I install the replacement battery and what step is often missed?

Connect the decoded chip connector firmly until it clicks; the most common mistake is leaving the plug partially seated, which prevents the smart-home roller shutter from recognising the new pack.

When will the 2000 mAh lithium-ion pack need replacing again?

Expect several years of daily solar-window cycles; after 2–3 full charge-discharge cycles the cell reaches peak capacity, and the integrated overcharge, over-discharge and short-circuit protection extends usable life.
