LiPoly Polymer Battery 3.7V 200mAh +

Excellent choice for Prototype with limited battery capacity

1. Lipoly Battery Good Safety Performance
The polymer lithium battery is made of aluminum-plastic flexible packaging in the structure. Once a safety hazard occurs, the liquid battery core is easy to explode, and the polymer lithium battery core can only be air-blasted at most.The protection circuit design of the polymer battery greatly increases the safety of the battery.
2. Light Weight
The weight of the lithium polymer battery is 40% lighter than the steel shell lithium battery of the same capacity specification, which is 20% lighter than the aluminum shell battery.
3. Large Capacity
Polymer batteries have a 10 to 15% higher capacity than steel shell batteries of the same size and are 5 to 10% higher than aluminum shell batteries.
4. Small Internal Resistance
The internal resistance of the polymer battery core is smaller than that of the general liquid battery. At present, the internal resistance of the domestic polymer battery core can even be less than 35mΩ, which greatly reduces the self-consumption of the battery, and supports the polymer lithium battery with large discharge current. It is an ideal choice for remote control models and is the most promising alternative to NiMH batteries.

Product Warranty
Product warranty is limited to original defects in material and workmanship for 90 days from the day of purchase. Warranty does not cover collateral damage, misuse, abuse, incorrect charging and other inappropriate use of this product.

Lipoly battery Life?
Standard: After 500 cycles, the capacity will be <80%.
It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.

What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answeri we gave is that you do not have this worry about these.
Because all lipoly battery we produced have reasonable tolerances:
Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.

What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.
