Kinstar manufactures a series of Lithium-ion power device batteries with protection circuit, voltage range from 3.6V to 14.8V, and capacity without a limitation.
Li-Polymer Power Device Batteries - Lithium-ion Polymer(Li-Polymer) is another advanced battery chemistry for portable power devices, which differ from conventional Lithium-ion batteries only in construction. A Li-Polymer battery can be shaped to fit into an array of devices. Kinstar offers a large number of Li-Polymer power device batteries with protection circuit, voltage range from 3.6V to 14.8V, and capacity without a limitation.
LiFePO4 Power Device Batteries - LiFePO4 batteries can be also used in some of power devices, which require better safety performance and longer service life. Kinstar offers both cylindrical and prismatic LiFePO4 cells or battery packs for portable power devices with protection circuit, voltage range from 3.2V to 12.8V, and capacity without a limitation.
Custom Lithium-ion Batteries - Kinstar manufactures high quality and high performance custom Lithium-ion (Li-ion) battery packs with BMS. By using advanced mechanical and electronic design tools, our expert battery design team will optimize your battery solutions for better manufacturability, safety, and reliability, giving you the most dependable and cost effective custom Lithium-ion batteres for your needs.
Custom Li-Polymer Batteries - Kinstar offers a wide range of custom Lithium-ion Polymer (Li-Polymer) batteries for many different applications, ranging from small Li-Polymer batteries for portable devices to remote control products, and large Li-Polymer batteries for eBikes and energy storage systems. Voltage range from 3.6V to 72V, and capacity without a limitation.
Custom LiFePO4 Batteries - LiFePO4 battery provides superior thermal and chemical stability, which provides better safety characteristics and longer cycle life than Lithium-ion and Li-Polymer batteries. Kinstar manufactures custom LiFePO4 battery packs with BMS for many applications, this gives our cusomer the most cost effective and dependable rechargeable LiFePO4 batteries.
Polygon Battery - Kinstar Li-ion 48V 20Ah polygon battery with dimensions 290×195×65×295×38×72mm, XT60 for discharging and female XLR for charging, build with 104pcs LG INR18650 M26 3.6V 2600mAh cells by configuration 13S8P. The strong BMS can maximum continuous load 30A current, and protecting the full battery pack from overcharging, overloading, overdischarging, shortcircuits and overtemperature.
High Capacity LiPo Battery - Kinstar provides some special Lithium-ion Polymer(Li-Polymer) cells/battery packs which capacity 15% higher than regular Li-Polymer cells/battery packs. For example, capacity of regular Li-Polymer cell model 603048 is 860mAh 3.7V, at Kinstar, you could have 603048 1000mAh with same sizes for achieving longer operating time.
