Preview	Guard-25A is the product in the "Guard" series. It has a special feature that makes it very interesting and attractive. Lithium Battery Balance Discharge Monitoring and Protection Design This function is a great innovation. With this function, the "Guard" series ESC can monitor the discharge voltage of EACH Li-xx (Li-ion/LiPo) cell in a battery pack at any time. So from now you needn't worry about the over-discharge problem for the weakest cell, the lithium battery pack will have a much longer life. This design helps R/C fans to reduce the cost for buying battery packs. 1 Specification 1.1 Output: Continuous 25A, Burst 35A up to 10 Secs. 1.2 Input Voltage: 2-4 cells lithium battery or 5-12 cells NiCd/NIMh battery. 1.3 BEC: 2A / 5V (Linear mode). 1.4 Max Speed: 210,000rpm for 2 Poles BLM, 70,000rpm for 6 poles BLM, 35,000rpm for 12 poles BLM. (BLM: BrushLess Motor) 1.5 Size: 45mm (L) * 26mm (W) * 12mm (H). 1.6 Weight: 27g. 2 Features 2.1 Safety Arming Feature: Regardless the throttle stick position, the motor will not spin after battery connected. 2.2 Throttle Calibration: Throttle range can be configured to provide best throttle linearity, fully compatible with all market available transmitters. 2.3 Programmable Items: Brake Setting: brake enabled / brake disabled. Battery Type: Li-xx(Li-ion or LiPo) / Ni-xx(NiMh or NiCd). Low Voltage Protection Mode(Cutoff Mode): Gradually reduce the output power / Cutoff the output power. Low Voltage Cutoff Protection Threshold (Cutoff Threshold): low / medium / high. Start Mode: normal / soft / very soft. Timing: low / medium / high. Reset: reset all the programmable items to its default setting. 2.4 Full Protection Features: Low voltage cutoff protection / over-heat protection / throttle signal lost protection. 3 Balance Discharge Monitoring and Protection Adapter (BDMP Adapter) We provides 2 types of BDMP adapters for user to choose. ......... Adapter #1 Adapter #2 4 Advantages 4.1 Military standard capacitor with extreme low resistance is used at voltage input section, this will increase the ability of prevention of unwanted RF Noise/ Interference during flying. 4.2 Extreme low resistance PCB is used at power output section to get the best current endurance capability. 4.3 Microprocessor uses separate voltage regulator IC, with good anti-jamming capability 4.4 Compatible with Hobbywing's Program Card. 4.5 Intellectual property rights of our own.
