Specification: Standard Voltage: 3.7V Rated Capacity: 1000mAh Weight: About 17g Size: 8.5*25*40（mmοΌ‰ Working Current: 1.5A Overcurrent protection: 2~3A Overcharge limit pressure: 4.25Β±0.05V Over-voltage limit pressure: 2.45Β±0.30V Charge current time: Standard Charging: 0.2C (8 hours); Fast charging: 0.5C (2.5 hours) The maximum charging current: 0.5C Continuous Dishcarge Current: 0.5C The maximum discharge current: 1C End-off voltage: 2.75V/pcs Allowable charging temperature: 0℃ ~ +45 ℃ Allowable discharge temperature: -10 ~ +60 ℃ Allowable storage temperature: -10 ~ +40 ℃( within 3 months); -10 ~ +30 ℃ ( within 6 months) Standard Charging Method: Charging this battery to 4.25V at 0.2C constant current, then charge the battery at a constant voltage of 4.2V till it's charging current≀ 0.05C. Package Including: 4 * 1000mAh 852540 3.7V Lithium Rechargeable Battery ## Features - Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid - 1000mAh: The recommended charging current is 0.2A, the maximum is not more than 1A. The discharge current is recommended 0.55A, and the maximum is not more than 3A - Over-discharge protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect - Overcharge protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, form an overcharge protection - Short circuit protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CXNQ3ZR | | Amperage | 1.5 Amps | | Antenna Location | ESP32 Development Board Whose Plug is SH1.25-2, Electronic Devices, Mesh Node T114 | | Battery Capacity | 1000 Milliamp Hours | | Battery Cell Composition | Lithium Polymer | | Battery Cell Type | Lithium Polymer | | Battery Weight | 17.76 Grams | | Best Sellers Rank | #73,717 in Health & Household ( See Top 100 in Health & Household ) #15 in 3.7V Batteries | | Brand | MakerFocus | | Customer Reviews | 4.5 out of 5 stars 332 Reviews | | Item Dimensions | 1.77 x 0.98 x 0.39 inches | | Item Weight | 17.96 Grams | | Manufacturer | MakerFocus | | Model Number | 7PVE55471137TGQWO5E | | Number of Batteries | 4 Lithium Ion batteries required.
