Please note: Single boards may be shipped via USPS First Class Large Letter locally from the Cleveland area, a tracking number may not be available. Orders of two (2) or more will be shipped as a First Class Package including a tracking number. Description: This standalone balance equalization board is used for a lithium battery pack without a balance feature. This standalone module does not charge or act as a low voltage/over charge cutoff. This board uses a resistor to balance each cell to 4.2v. This board can also be added to an existing BMS battery setup to boost the effectiveness of the balancing function by increasing maximum balancing capacity. Battery compatibility: Voltage of 2.5V – 4.2V lithium battery (18650, 26650, LiPo, Li-ion)Battery voltage range: 25.9v – 29.4vMaximum balance current: 66mABoard Size: approx. 37.3*25.8*2.4mmPackage includes: 1 x 7s Lithium Battery Balance Board Wiring Instructions:B- Connect the negative terminal of the battery 1(-)B1 connects between battery 1(+) and battery 2(-)B2 connects between battery 2(+) and battery 3(-)B3 connects between battery 3(+) and battery 4(-)B4 connects between battery 4(+) and battery 5(-)B5 connects between battery 5(+) and battery 6(-)B6 connects between battery 6(+) and battery 7(-)B7 is connected to the positive terminal of battery 7(+) 7s 66mA 25.9v – 29.4v Li-ion Lithium Battery Balance Board Standalone BMS Add-on

4S 16.8v Balance Board 4.2v Li-ion Lithium Standalone BMS Add-on

Example Uses: 1. This balance module can be used in parallel with a BMS to boost the balance efficiency of battery/BMS setup. 2. Secondly, the balance module can be used without a BMS, and will keep the individual battery cells within healthy balance levels. 3. Lastly, this balance module can be used in place of a traditional BMS. In specific setups where a battery is connected stable voltage source such as a 16.8v charger or solar charge controller (16.8v) and the output is controlled by a low voltage cutoff such as a inverter.

10pcs TP4056 5V 1A USB Type-C USB-C Lithium Battery Charging & Protection Board

10pcs TP4056 5V 1A USB Type-C USB-C Lithium Battery Charging & Protection Board Dual Function: 1) Charge lithium cells from a 5V power source 2) Protect battery from over-discharge and over-current Charge input: 5V DC • Maximum charge current: 1000mA • Charge cut-off: 4.2V Discharge protection cut-off: 2.5V • Over-current protection cut-off: 3A USB-C input • Size: 2.6×1.7cm This is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. This module provides constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering. The device to be powered by the battery is connected to the module's OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged. During use, if the battery voltage drops below about 2.4V, the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low and self-destructing. When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur. The module also protects against overcurrent and short-circuit protection – it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs. This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don't have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell. The USB port is for charging only.
