Battery for Water Quality Analyzer
1.Technical parameters：
The Water Quality Analyzer is an important instrument for analyzing the water quality. It equipped with mini electric pump, mixer, heater and monitor. The instant start-up current reach to 20A, and the standard working current is 4~5A. This type of battery should be high energy and light weight, long time battery cycle life than ordinary battery.
Our lithium battery is designed with 30A over current protection and 7A continuous working current.

PCBA Specification:
PCM：This battery pack applied special designed protection circuit：
Over charge, Over discharge, Short circuit and over current protection. Prevent battery from fire and explosion.
Protection IC：
The protection IC with real time detection function: over charge, such as over discharge, over current and short circuit protection. It ensured battery security and stability.
MOSFET：MOSFET is the auto switch, which keeps the voltage in a stable period.
Temperature switch: It’s designed for thermal detection and protection. When the temperature of the battery up to the range of 70 ± 5 ℃, temperature switch will cut of the current to protect the battery.
Cell type: 18650/2500mAh/3.7V Li-ion cell（SANYO）
