This intelligent 11.1V 20C lipo battery is suitable for medical drill application and has come out on the market. Fello Tech adopts developed lithium polymer battery technology on the drill battery schemes, which makes the battery have outstanding endurance capability and high power to 20C continuous discharge. Compared to other brands, Fello Tech medical drill battery contains characters of high capacity, stable charging and high rate discharge performance.

Design requirements:

Ⅰ. The battery design requirements of medical drill

According to the requirements of product specification and customers, the battery design of Intelligent medica drill needs to assort with the host machine, and integrate high safety performance, good charging and discharging performance and outstanding long-term application reliability into the solutions.

Ⅱ. The battery design scheme of BeiDou Navigation Satellite System:

1）Guard plate (PCM): it is a protective circuit designed for rechargeable high capacity battery pack, which provides the battery with protective functions of overcharging, over-discharging, short circuit, overcurrent and over-temperature.

2）Protection IC: the chip has protective function in the design scheme. It can monitor the cell online at any time, so that the cell can work under safe, stable and efficient circumstance.

3）FUSE: it is a 40A fuse design for Secondary protective function. Fuse has overcurrent protective function. Apply fuse in battery can prevent insecure event of charging and discharging under large current.

4）Lithium polymer (lipo) battery: FT683490/1900mAh/11.1V/ 20C continuous discharge

5）MOSFET: it works as a switch in the protective circuit.

6）Encapsulation of battery pack: the manufacture of external packing depends on customers’ requirements.

7）Anti-shock property: fill the interior battery by epoxy resin or neutral silica gel, which has resulted in advanced anti-shock property.
