To ensure maximum operational safety and prolong the functional life of your lithium-ion investment, please strictly adhere to the following technical guidelines. Comprehensive safety operation manuals and MSDS documents are available for download via our technical support portal.
Charging Requirements: Always use a dedicated lithium-ion battery charger with matching voltage and current parameters (8.4V). Do not use a non-regulated power supply for direct charging to prevent overcharging, thermal runaway, and potential electrical hazards.
Prohibitions: Do not throw the battery pack into fire, disassemble the outer wrap, crush, puncture it, or short-circuit the positive and negative terminals. Do not use the battery at excessively high temperatures (>60°C) or low temperatures (<0°C for charging, < -20°C for discharging).
Installation and Use: During physical installation into your device casing, avoid pulling or compressing the 80mm wires, and ensure secure, vibration-free terminal connections. The equipment design should provide adequate thermal ventilation space around the battery pack.
Storage and Transportation: When the host device is not in use for extended periods, keep the battery charge level balanced between 30% and 70% and store it in a cool, dry environment. During transportation, ensure proper physical insulation to prevent accidental terminal short circuits.
Disposal: This product is manufactured as an environmentally friendly battery, but after its lifespan ends, do not dispose of it indiscriminately in standard waste streams. It must be recycled according to local environmental regulations and e-waste protocols.
A: Absolutely not. You must use a dedicated lithium-ion battery charger with an output voltage of 8.4V and a constant current/constant voltage (CC/CV) charging algorithm. Using a standard AC/DC adapter with an incompatible voltage will permanently damage the protection circuit board or cause severe overcharging, posing a direct risk of fire or explosion.
A: The protection board is designed as the last line of defense against catastrophic failure, not a daily operational switch. When the voltage drops to the over-discharge protection point (approximately 6.0V), the protection board will cut off the output to protect the battery cells. However, frequently triggering this hardware protection will degrade the battery chemistry and shorten its life. It is highly recommended that your device features a software-level low-voltage alarm or shutdown function to stop usage and prompt a recharge when the voltage drops to approximately 6.6V (3.3V per cell).
A: In principle, it is strictly not recommended to directly connect multiple finished battery packs in parallel on your own. Even if they are the exact same model from the same batch, there may be slight differences in their internal state, resting voltage, and internal resistance. Direct parallel connection under these conditions may cause circulating currents between the packs, negatively affecting performance and safety. If your project requires a larger capacity, please utilize our customization services to order a factory-balanced 2-series multi-parallel (2SXP) battery pack.
A: It is perfectly sufficient for continuous operation. Your device's standard operating current (800mA) is less than the battery's maximum continuous discharge current rating (1000mA), which keeps the thermal generation within the safe operational range. However, please analyze your device's startup or pulse power requirements to ensure that the instantaneous peak current does not exceed the overcurrent protection threshold of the built-in protection board (which is calibrated and usually set at around 2A).
A: The dimensions listed in the technical specifications table (Φ18mm × 110mm) refer strictly to the maximum external dimensions of the shrink-wrapped battery cell body. The flexible connecting wires (measuring approximately 80mm long) and the rigid plastic terminals are not included in this dimensional measurement. When engineering the internal battery compartment for your hardware, you must reserve extra physical space to safely route and house the wires without pinching them.
