請教有關“battery package”的問題!

Still there was no Polyswitch built in. - NOW build in Polyswitch
2) Also the charging electronic is not built in.
The whole item needs to shut down before the electronic of the battery.
For that you need an additional protection for the Direct Charger, additional to the protection of the built in battery.
Otherwise the battery of the direct charger will be defective after several times of use.

電池不太懂,但正好看到polyswitch的e文解釋
A PolySwitch is a Polymer form of Positive temperature coefficient resistor (PPTC) which acts as a self repairing fuse

仍然沒有內置PPTC(自恢復保險絲,正溫度系數(shù)保險絲),現(xiàn)在請增加內置PPTC.
2)充電器也沒有,整個項目在(電子電池??)前要關閉,所以你需要對充電器附加一個保護,對內置電池附加一個保護.
否則在幾次使用后電池將有缺陷
