DTP-SP20S044 is a software protection board
scheme specially designed for 8~20 strings of lithium
battery packs. The product adopts architecture of
front-end acquisition chip + MCU, and some
parameters can be flexibly adjusted through the host
computer according to customer needs.
Integrated GPS, 4G, BMS functions in one, can be
used for two-wheeled vehicle power change, battery
management, etc.
