LiPoly Polymer Battery 3.7V 200mAh +

Custom Best LiPoly Battery For Prototype/Long life Lipoly Battery/More Safety +

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.
