battery equaliser 4S 100A BMS 12.8V Lithium iron phosphate battery 14.8V lithium battery protection Board with balanced Version Split port (Size : 3.7V)

Description

• Battery energy transfer: a practical and multi-functional battery equalizer can be used for battery overshoot and over discharge protection.
• Battery voltage balancer: it is used for the batteries which are connected in series to keep the voltage of batteries are equal.
• Battery balancer: the equalizer starts to work when there are between two batteries.
• Durable battery equalizer: widely applied in -acid battery, nickel- or nickel- battery, etc.
• Voltage balance: using this shell is strong and durable for long-serving life.

Model: 4S 100A BMS 12.8V Lithium iron phosphate battery 14.8V lithium battery protection Board with balanced Version Split port
Product Size: 70 * 60 * 8.5mm (balanced version)
Charging voltage: 16.8V
Quiescent Current:less than 30uA
Upper limit operating current: 100A (Attention the temperature)
Upper limit instantaneous current: 120A
Overcharge voltage range:4.2V-4.3V
Over-discharge voltage range:2.45V-2.55V
Short circuit protection: protection, delay self-recovery.
Precautions:
1.Strictly according to the diagram wiring:OV(B-),3.7V(B1),7.4V(B2),11.1V(B3), 14.8V(B+ )
Do not intentionally short circuit.
2.After charging the line, charge it first, then there will be output.
3.When connecting 4 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. In the discharge test, the group with the fastest voltage drop was a poor battery.

Note:
In order to make the balance effect better and consistent, try to charge with a 17V,The current is charged with a switching source of 0.2 times the capacity switching power supply. Because the equalization current of the equalization IC is about 65mA, and most of the 16.8V lithium battery chargers on the market, the charging current detection will be self-stop when it is lower than 100mA. If there is no balance, there will be electricity coming in, which will cause the voltage of each group to be unbalanced.
Regarding the voltage drop of the battery voltage and the output terminal voltage, the working principle of this type of protection board is the negative pole protection. When the combination is good, there will be a voltage drop of 0.1-0.3V, and circulating and charging several times will lower the voltage drop voltage. It is normal. The charger should try not to use the 16V power supply. The 4-string ferric pho
