+The diagram below shows the module discharge. The battery is a 2-series configuration, and the connected batteries must support a 20A discharge current. This can be achieved by connecting batteries in parallel or by purchasing batteries with a higher discharge current.
38
+
39
+For example, if the battery is 2000mAh with a 10C discharge rate, then only 2 series and 2 parallel (2S2P) are needed, which can provide a discharge current of 40A.
40
+
41
+For stable discharge, 2 series and 4 parallel (2S4P) are required, and attention should be paid to heat dissipation, as the battery power will drop quickly during discharge.

+- To successfully start an electric drill, you need two 10C-20C power batteries, or four 5C-10C power batteries (recommended battery models: Sony VTC4S, VTC4A, VTC5, VTC6). For the 0V and 8.4V connection wires, use copper wires of at least 2 square millimeters (do not use strips).
46
+- When welding the battery for the first time, you need to charge it first to get output. Strictly follow the diagram to connect 0V, 4.2V, and 8.4V. When welding wires, do not touch any components on the board, and do not intentionally short-circuit.
47
+- When welding the battery for the first time or while charging, as long as any single cell exceeds 4.2V, the "430" resistor will heat up to discharge (discharge stops when it drops to about 4.19V). If the "430" resistor becomes very hot (too hot to touch), please check if the wiring is incorrect.

-LiFePO₄ (Lithium Iron Phosphate) is a type of Lithium-ion (Li-ion) battery, but it uses iron phosphate (FePO₄) as the cathode material instead of more commonly used materials like cobalt, manganese, or nickel.
10
-
11
-Key Characteristics:
12

-## Why is LiFePO4 considered a type of lithium-ion battery?
100
-
101
-Both LiFePO4 and other lithium-ion batteries store energy through the movement of lithium ions between electrodes.
102
-
103
-The key difference lies in the cathode material (正极材料):
104
-- LiFePO4 uses **lithium iron phosphate**. (磷酸铁锂)
105
-- Generic lithium-ion batteries often use **cobalt-based chemistries** (e.g., LiCoO₂). (基于钴的化学材料)

-## When to Choose LiFePO4 Over Other Lithium-Ion Chemistries?
109
-
110
-1. Safety is a priority:
111
-LiFePO4 is more thermally stable and less likely to overheat, catch fire, or explode.
112
-
113
-2. Long lifespan needed:
114
-Ideal for applications requiring thousands of charge/discharge cycles (e.g., solar systems, EVs, backup power).
115
-
116
-3. High discharge/charge rates:
117
-Suitable for applications like power tools or outdoor equipment.
118
-
119
-4. Eco-consciousness:
120
-LiFePO4 batteries are free of cobalt, which is often associated with environmental and ethical issues.

-## safest battery - Lithium Iron Phosphate (LiFePO4)
127
-
128
-The safest batteries to use, especially in terms of preventing fires or explosions, are Lithium Iron Phosphate (LiFePO4) batteries. They are known for their thermal and chemical stability compared to other lithium-ion batteries. Here are some key points about them:
129
-
130
-- Safety: LiFePO4 batteries are less likely to overheat, catch fire, or explode because of their higher thermal runaway threshold. They also have better stability during overcharging and short-circuit conditions.
131
-- Longer lifespan: These batteries tend to last longer than other types, reducing the need for frequent replacements.
132
-- Stable chemistry: Their chemical structure is more resistant to thermal changes, which makes them safer even in extreme conditions.
