651723 150mAh 20C Micro RC Aircraft Battery

Why Choose LithoTop for Small High Rate LiPo Batteries?

Small high rate LiPo batteries require more than compact size. For stable performance, the battery must control internal resistance, voltage consistency, discharge capability, connector reliability, and production repeatability. LithoTop supports customers from sample evaluation to mass production with professional engineering support and strict quality inspection.

For compact electronic products, LithoTop can help evaluate battery size, discharge current, charging method, protection circuit, connector type, and real working conditions before confirming the final battery design. This helps customers reduce development risk and improve product reliability.

01 – Mini Drone Project from France

A French consumer electronics company was developing a mini indoor drone for children and hobby users. The main challenge was battery weight. Their previous battery could provide enough runtime, but it made the drone too heavy and reduced flight stability. When the battery size was reduced, the drone suffered from weak takeoff power and poor acceleration.

The customer contacted LithoTop because they needed a small high rate LiPo battery that could balance lightweight design and strong discharge performance. LithoTop reviewed the drone motor power, propeller size, flight controller demand, battery compartment space, charging method, and target flight time.

After analysis, LithoTop recommended the 651723 3.7V 150mAh 20C High Rate LiPo Battery. Our engineering team judged that the customer did not need a larger capacity cell, because extra weight would directly affect flight control. A 150mAh 20C battery provided a better balance between weight, output power, and compact installation.

During sample development, LithoTop optimized the wire length, connector type, cable outlet direction, and pack insulation to fit the drone structure. Sample testing included takeoff power testing, short flight endurance testing, voltage drop checking, repeated charge-discharge cycling, and temperature monitoring after continuous operation.

Before mass production, both teams confirmed samples, connector specifications, cable direction, battery dimensions, and batch inspection standards. After launch, the drone showed improved takeoff response and more stable indoor flight performance. For the customer, this helped reduce product complaints and improve the user experience for entry-level drone users.

02 – Wireless Sensor Device Project from Germany

A German IoT device company was developing a compact wireless sensor used for equipment status monitoring. The sensor needed to remain small and lightweight, but it also required short high-current output when transmitting data. Their previous standard LiPo battery worked during standby, but voltage dropped when the wireless module started transmission.

The customer approached LithoTop because they needed a reliable battery manufacturer that could provide a compact cell with better discharge response. LithoTop analyzed the sensor’s standby current, transmission current peak, charging circuit, enclosure space, working environment, and expected production quantity.

Based on this evaluation, LithoTop recommended the 651723 3.7V 150mAh 20C LiPo battery. The 20C rate helped support short current peaks during wireless transmission, while the 150mAh capacity kept the device compact and easy to install inside the customer’s enclosure.

During prototype development, LithoTop adjusted the connector selection, wire length, PCM protection option, and battery label design to match the customer’s assembly process. Sample batteries were tested through standby simulation, transmission pulse testing, voltage stability checking, charging compatibility testing, and installation fit verification.

Before mass production, the customer confirmed the approved sample, electrical performance, connector durability, packaging method, and incoming inspection standard. LithoTop then controlled mass production according to the confirmed golden sample.

The final battery solution helped the sensor maintain stable operation during data transmission and reduced unexpected power interruptions. For the customer, this improved field reliability and made the product more suitable for long-term IoT monitoring applications.
