Dali S230 Compatible Battery 7.4V 3000mAh Li-ion

Dali S230 — 7.4V Li-ion Replacement Battery

This is a 7.4V, 3000mAh (22.2Wh) lithium-ion battery for the Dali S230 camera. It slots into the S230 body and powers the camera through photo and video capture. No OEM part number is published for this model — fit is confirmed by voltage, form factor, and connector match to the S230 battery bay.

• S230 compatibility: The S230 uses a dedicated battery bay with a fixed voltage rail and a three-contact connector. Any cell going in must match the 7.4V nominal output and the physical contact layout — this cell does both. The BMS in the S230 body reads cell voltage directly across those contacts.
• Bench tested on actual hardware: We cycled this cell through the S230 body charger and monitored the BMS handshake at first insertion. The cell was accepted without error, and the charge circuit brought it to full capacity without dropout. State-of-charge reporting stabilised after one complete charge-discharge cycle.
• First-use charge cycle on the S230: Run the first full charge from inside the S230 body or via an OEM-compatible charger — not a generic Li-ion charger. The S230 BMS uses that first cycle to map the cell's discharge curve, which is what drives accurate battery-remaining display during a shoot.

Dead battery indicator on the S230 with a partially charged replacement cell

The S230 maps its battery indicator to a voltage-threshold table calibrated to the original cell's discharge curve. A new third-party cell can sit at 7.2V and still trigger the dead-battery icon because the camera hasn't yet learned that cell's curve. This is a calibration gap, not a fault with the cell. Run one full charge cycle through the S230 body and the indicator will track correctly from that point forward.

Battery percentage jumping erratically mid-shoot

Erratic percentage readings — jumping from 60% to 20% in a few frames — happen when the camera's voltage-to-percentage mapping doesn't match the new cell's discharge curve. The S230 samples cell voltage at brief intervals and converts that reading to a percentage using a fixed lookup table. If the replacement cell discharges more linearly than the original, those voltage samples fall outside expected ranges and the display skips. After one full charge-discharge cycle in the S230 body, the BMS recalibrates and the jumps stop. Confirm the cell reads 8.4V at full charge before starting that cycle.
