PCB For 4 Cells Bms Battery Management System 14.4V Li-Ion Li-Polymer Lithium Battery For Electric Tool
Battery Management System (BMS)
You'll need a BMS to monitor your cells during charging and discharging. Basically it protects the cells from getting drained too far or getting overcharged. When choosing a BMS you need to match two main factors: voltage and current rate (more important for discharge than charge current). If you are building a 36V battery, you'll need a 36V BMS (or usually called 10s, meaning 10 cells in series) to match your battery. A 48V battery uses a 13s BMS and a 52V battery uses a 14s BMS. Just make sure you choose a BMS configured for the same amount of cells as the battery you are building. Also remember to check the discharge current. If you want your battery to be able to handle 20A continuously, choose a BMS that is rated at least 20A, and higher is better to give you a safety buffer.
● The protection board is for 4S lithium batteries, it can be used for Li-ion/Li-polymer batteries
● Stable various protective functions for charging and discharging, such as accurate overcharge protection, over-discharge protection, over current protection and short circuit protection

Ryder Electronics established in Shenzhen on July 18, 2005, mainly in the business of battery packs. In 2009 the company passed ISO9001 and improved the product quality standard to fulfill the high-end requirements from our customers.
In 2012, Ryder Electronics moved to a new facility and expend the production capacity, the Productivity improved nearly 10 times than before.
In 2013, Ryder Electronics imported ERP (SAP) system to supervise order execution process.
In 2017, Ryder Electronics expanded the SMT, imported high-speed patch machine from Germany.
Until now the factory grows into a modern enterprise which integrated injection molding, PCB designing, SMT and battery pack assembling services.
In 2018 the company passed ISO14001certification, introduced automated battery production line to further improve the production quality and capacity.
