small 3.7 v polymer battery

Small lithium rechargeable polymer battery, LIP 281622, 3.7V,60mAh with 0.222Wh.

The best small 3.7 v polymer battery supplier, very strictly control on size, pay much attention on safety, with moutiple protection, built in Japan IC&MOS to protect cells from over-discharge, over-voltage,over-charge,over-current, short-cut. Also, if you want to add a detector for temperature, we can give soluation to add NTC. If you have more requriements on the battery pack, our engineer can give professional power soluation.

Also, different models of connectors can be choosing based on your different requirements. The connectors we mainly use are famous brand of  Hirose, Molex, and JST, etc. 

The 3.7V Lipo battery which assembled with protection circuit, can be protected cells voltage from rising too high, or going downing too low. For example, if we set the battery cutted off at 3.0V, when the cells are discharged from 4.25V to 3.0V, then the PCM will stop the discharge at 3.0V to protect the cells from over-discharge.

With the progress of society, many customers need an ultra-thin small 3.7v polymer battery for thinnest application, like bank card,mini mobile card, information card,etc.Lipower have the cells with thickness from 0.4mm to 3.0mm. Some customers who develop mini mobile phone or smart card or the other thinner applications. They need a super thin battery which can provide low power but longer working time.  The inside cell need to be thinner to meet 0.3mm, 0.2mm or 0.1mm. Lipower production with unique materials, Insulating film,Aluminum-plastic film,  Nickel tape that can improve the production process.
