18650 電池 3.7V 轉 5V2A 升壓模組 DIY 行動電源模組 充電電池要求：
可用電池：18650 電池、手機電池、平板電池、MP3電池等3.7V-4.2V聚合物鋰電池，可單節（片）供電，也可多節（片）並聯供電（不支持串聯，不可以串聯）。（注意：並聯增加容量，串聯是增加電壓，只能並聯用！）可以並聯2-6節18650電池！！！ 不可用電池：乾電池、蓄電池、1.2V可充電電池、鎳氫電池、3.2V鐵鋰聚合物鋰電池等。

18650 電池 3.7V 轉 5V2A 升壓模組 產品安裝時需注意以下幾點：

• 1、電池要並聯，電壓要在3.2-4.2V之間才能工作，18650平頭與聚合物電池均可。
• 2、電池正接主板B+ 負接B-，裝反必燒主板。
• 3、新舊電池、型號品牌不一致電池不可混用。

輸入端口：MicroUSB（安卓口）
輸入要求：5V恆壓電源都可以做充電輸入電源，最匹配充電器為5V1A以上
輸出端口：USB
輸出參數：5V1A/5V2A

Requirements for rechargeable batteries:

Available battery: 18650 battery, cell phone battery, flat battery, MP3 battery, etc. 3.7V-4.2V polymer lithium battery can be single section (chip) power supply, can also be multi-section (chip) parallel power supply (not in series, not in series ). (Note: increase the capacity in parallel, the series is to increase the voltage, can only be used in parallel!)

Can be parallel 2-6 18650 battery.

Not available Battery: dry batteries, batteries, 1.2V rechargeable batteries, nickel-metal hydride batteries, 3.2V lithium iron polymer lithium batteries.

Product installation should pay attention to the following points:

• the battery should be in parallel, the voltage between 3.2-4.2V to work, 18650 flat and polymer batteries can be;
• the battery is connected to the motherboard B + negative access B-, installed anti-burning motherboard;
• the old and new batteries, models, inconsistent battery brand can not be mixed.
