BlackView A200 Pro Compatible Battery LiNDC045PAHP 3.87V 4900mAh

BlackView A200 Pro — 3.87V Li-Polymer Replacement Battery (LiNDC045PAHP)

This is a 3.87V, 4900mAh Li-Polymer battery built to fit the BlackView A200 Pro smartphone. It matches the OEM part number LiNDC045PAHP and slots into the original battery bay. Voltage, capacity, and connector position are confirmed against the A200 Pro hardware before shipping.

• A200 Pro fitment: The A200 Pro uses a dedicated battery bay with a fixed flex connector orientation. This cell matches that connector pinout and physical dimensions, so the fuel gauge IC on the motherboard can communicate with the BMS without a handshake error on boot.
• Bench tested on actual hardware: We cycled this cell through a full discharge-charge sequence and monitored BMS communication with the charge IC. The protection circuit responded correctly to cutoff thresholds at both ends of the voltage range — no spurious trips detected.
• First-cycle calibration tip: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC build an accurate discharge curve against the new cell before high-current charging begins on an uncalibrated coulomb counter.

Why the A200 Pro reports wrong battery percentage after a cell swap

The A200 Pro uses a fuel gauge IC that builds its charge model from previous cell discharge curves stored in memory. When a new cell goes in, that stored model no longer matches the actual discharge behaviour of the fresh Li-Polymer cell. The gauge reads the voltage curve against outdated reference data, so it reports percentages that are either too high or too low. One full discharge to auto-shutoff followed by a complete charge to 100% lets the IC reset its calibration against the new cell.

Sudden shutdown at 20–30% remaining on the replacement cell

This is a voltage cliff, not a capacity fault. Under high-draw loads — active LTE, a bright display, or a demanding app — the cell voltage sags sharply. If it dips below the BMS protection threshold before the fuel gauge IC sees 0%, the phone shuts off with charge apparently remaining. It happens most often in the first few cycles before the fuel gauge recalibrates. Run two full discharge-charge cycles and check whether the cutoff point shifts; if it persists past cycle three, check that the flex connector is fully seated and that contact resistance at the motherboard connector is below 0.5Ω.
