70A High-Current Module 4-90V Wide Voltage Input Solar Anti-Backflow Protection Board for Drone RC BEC System

70A High-Current Module 4-90V Wide Voltage Input Solar Anti-Backflow Protection Board for Drone RC BEC System Description

4-90V wide voltage range, suitable for multiple scenarios
Low pressure drop prevents backflow and protects against overheating
Replaces traditional diodes, offering high efficiency and low loss
Dedicated solar-powered rectifier for more stable charging

Things to note
1. The negative terminal of the main current loop does not need to pass through the module, but the negative terminal the module must be connected (a thin wire can be used).
2. It can only be used for , with an operating frequency not exceeding 150Hz, and cannot be used for AC rectification.
3. Be aware of surge voltage damage to the chip. For high operating voltages and inductive loads, please add TVS diodes and electrolytic capacitors at the input and output to absorb surge voltage.
4. When the operating current is large and the heat generation is relatively large, heat dissipation needs to be strengthened (by increasing the heat sink or using air cooling).
5. Multiple units can be connected in parallel to increase the current, or multiple units can be connected in parallel to increase the number of channels.
6. When using main and auxiliary batteries in parallel, if the main battery does not have an ideal diode, ensure that the auxiliary battery voltage does not exceed the main battery voltage. If both the main and auxiliary batteries have ideal diodes connected, there is no voltage difference requirement when connected in parallel.
