The battery board manages charging, energy, and security for drones, robots, and RC toys. It really works with 2 to 4 cell batteries.
The TIDA-00982 is a battery administration system (BMS) reference design from Texas Devices, tailor-made for 2S1P Li-Poly battery packs utilized in non-military drones, robots, and RC initiatives. It brings collectively important battery features—charging, gas gauging, safety, and balancing—on a single compact PCB. It consists of onboard State of Cost (SOC) monitoring, SMBUS communication, and a configurable buck regulator that gives both 3.3 V or 5 V at 500 mA, appropriate for powering microcontrollers or exterior elements. This design helps 2S by default however will be adjusted for 3S or 4S methods with minor modifications. It’s suitable with drones within the 200 mm and 250 mm class, in addition to RC automobiles, helicopters, and robotic methods.
This board is designed to deal with as much as 30 A peak present and 15 A steady present, making it appropriate for functions that demand excessive energy, comparable to speedy motor acceleration. It was examined with a 2S1P 1.3-Ah battery at a 25 C discharge price. The charger on the board is preset to 1.3 A (1 C), however will be elevated to 4 A to help bigger batteries as much as 4 Ah, requiring solely a easy adjustment to the charging present. The design additionally helps each the bq4050 CEDV gauge and the bq40Z50 Impedance Monitor gauge, that are pin-to-pin suitable, permitting customers to change between algorithms primarily based on utility wants.
By combining all of the important BMS features into one board, TIDA-00982 considerably simplifies the design course of. Engineers shouldn’t have to supply or configure separate modules for gauging, charging, balancing, and safety. This compact integration additionally reduces board measurement and wiring complexity, which is especially helpful for small-scale drone and RC platforms. The flexibility to precisely gauge battery standing throughout excessive discharge occasions—as much as 25–50 C—offers it a serious benefit over different designs that will fail underneath such load.
The board’s versatile structure means it could actually help a spread of battery sizes and configurations with minimal modifications. The buck regulator permits simple voltage changes for powering exterior circuits. Moreover, the usage of normal, low-cost connectors ensures compatibility with off-the-shelf elements, lowering price and simplifying meeting.
For builders and engineers, the design affords clear advantages. It permits speedy prototyping and testing of good battery options with out requiring deep experience in battery electronics. Its high-current dealing with ensures secure efficiency underneath demanding circumstances, comparable to drone take-off or robotic motion. The onboard gas gauging, safety, and SOC indicators assist monitor battery well being and efficiency in actual time, contributing to longer battery life and safer operation.
