Hip Top PV-BL11 Danger 3 Compatible Battery 3.7V 1600mAh

Hip Top Danger 3 — 3.7V Li-ion Replacement Battery (PV-BL11)

This 3.7V, 1600mAh lithium-ion cell replaces the original battery in the Hip Top Danger 3 smartphone. It matches OEM part numbers PV-BL11 and EA-BL12. Swap it in when the original cell no longer holds a charge or the phone shuts down unexpectedly.

• Danger 3 fitment: The Danger 3 uses a single-cell Li-ion pack with a proprietary connector and a BMS that handshakes with the device's charge IC. This cell matches that connector pinout and voltage rail so the charge IC accepts it without fault codes.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Danger 3 platform and confirmed the BMS communicated correctly with the phone's fuel gauge IC. No charge termination errors appeared during the test cycle.
• Fuel gauge recalibration on first use: After installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter to the new cell's discharge curve before any high-current charging session begins.

Sudden shutdown at 20–30% on a replacement cell

The Danger 3's fuel gauge IC stores a discharge curve calibrated to the original cell. A new cell with a slightly different internal resistance profile hits a voltage cliff at a different state of charge. When the modem fires up for a call or the screen brightness spikes, current draw pulls cell voltage below the BMS cutoff threshold — even though the gauge still reads 20–30%. One full discharge-charge cycle at standard rate resets the coulomb counter and the shutdowns typically stop.

Phone warm near the battery compartment on first charge

A fresh cell starts with higher internal impedance than a broken-in one. The charge IC responds by pushing slightly more voltage to maintain target current, which generates extra heat at the cell surface. This is normal for the first one or two charge cycles and fades as impedance settles. If the warmth continues past the second full charge, check that nothing is blocking airflow around the battery cover and verify charger output does not exceed the rated input voltage.
