2.lithium battery protection board

With the wide application of lithium batteries in the home-energy storage industry, ITK-BMS-C19 module stands out in the home-energy storage BMS industry because of its excellent performance, high reliability, and cost-effective characteristics. Multi-communication methods of BT/ RS485/RS232S/ CAN, it is connected to the computer host computer and the mobile APP to carry out intelligent management of the lithium battery. 
1. ITK-BMS-C19 intelligent BMS can be used for 8S-18S 50a-200a battery pack 
2. Functions: over-charging protection,  over-discharging protection, over-current protection, short circuit protection, temperature protection, balance  function etc.
3. we can develop PCM of different sizes and structures for customers.
The protection board is made of high quality MOS (such as Infineon) and IC to keep your battery for a longer cycle life. When with a high working current, the high quality aluminum alloy heat sink has a good heat dissipation function.
