The 501010 is an ultra-compact, rechargeable lithium-ion polymer battery designed for space-constrained, low-power electronic applications. Its thin pouch construction provides high energy density and flexible form-factor integration for miniature devices. They are the best go-to option for many wireless earbuds.

Lithium-ion polymer (Li-Po) batteries are thin, light, and powerful. When ultimately charged, they output 4.2V to 3.7V. This battery has a capacity of 35 mAh, for a total of about 0.1295 Wh. If you need a larger (or smaller!) battery, we have an extensive range of Lithium-ion polymer batteries.

These cells do not have BMS on Board Due to Size. BMS protection is controlled by the Headphone internal protection circuitry or by the Charging Pod, which keeps the battery voltage from rising too high (overcharging) or falling too low (overdischarging). 

The BMS will cut out when completely dead at 2.75V. It will also protect against output shorts. Even with this protection, you must use only a LiPo constant-voltage/current charger to recharge them at 0.5C or less.

The batteries come pre-attached with 2-Tinned Flat tabs 

Compatable with: i7 i8 i9s i10 TWS Bluetooth Headset

Usage & Precaution:

Lithium-ion and lithium polymer cells are powerful batteries; you should take extreme care when using them. If exposed to abusive conditions, they may get hot, explode, or ignite and cause serious injury. Unfortunately, we can not replace batteries damaged by non-compliant chargers or equipment.
Be sure to follow the safety warnings listed below:

Do not
  • Overcharge: Ensure the charger voltage does not exceed the battery’s full charge voltage.
  • Over-discharge: Ensure the equipment you use with this battery does not draw more current from it than the stated “Maximum Continuous Discharge Current.”
  • Leaving batteries discharged for an extended period can incur irreversible damage
  • by placing the battery in fire, heating, or direct sunlight.
  • Install the battery backward so the polarity is reversed.
  • Connect the battery’s positive and negative terminals with any metal object,
  • expose the battery to water or saltwater, or let the battery get wet.
  • Disassemble or modify the battery. The battery contains safety and protection devices.

 

Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for damage, loose wiring, or the possibility of short circuits. As with all Lithium-ion polymer batteries and any power source, they should be used by experts who are comfortable working with power supplies.

Note Please check your current cable orientation, as there is no  Industry Standard for Cable setup. Wrong orientation can damage the cell and your item.
