DROK DC Buck Converter, 6pcs Mini Voltage Regulator DC 4.5-20V 12V 9V Step Down to 5V Reducer Board 3A 10W Fixed Adjustable Volt Output Step-Down Transformer Power Supply Stabilizer Module
- Parameter --- For DROK 12V to 5V voltage regulator: Input voltage: DC 4.5-20V; Output voltage can be adjustable or fixed. Adjustable range: 1-16V; Fixed voltage: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V; Output current: Max 3A (peak: 3A, long-term: within 2A); Power: 10W.
- Output Voltage Adjustable or Fixable --- These tiny 12v to 5v step down converters can be variable at output voltage. The small board is default to be used for output voltage adjustment. If you want to get fixed voltage output, you need to cut off the Pad A by using a sharp thing such as a knife then weld together the port of the fixed voltage you want.
- High Efficiency --- Conversion efficiency: Up to 97% (typical value: >90% when step down 12V to 5V 2A).
- Protection and Enable Control --- Output short circuit protection, but please do not keep short circuit for a long time. The integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users.
- NOTE --- This mini buck converter is very tiny, much smaller than a 1-dollar coin, nearly a half of the coin.

6S 7S 8S 5A Active Equalizer Balancer 8S Equalizer Lifepo4 Li-ion Lithium Lipo/Titanate LTO Energy Transfer Board Whole Group Capacitor Balancer PCB
- 【USE Tips】The voltage gap of each battery must be within 0.5V. When the battery voltage difference does not reach more than 0.1V, the light on the balance board is triggered by mistake. The light actually has no balance current when it lights up, and it will automatically go out after a period of time. So We suggest re-plugging the cable to solve the problem.【Note that】It takes time to equalize the voltage, hot is normal and it does not take effect immediately after plugging it in.
- 【NOTE】: Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the battery pack are correct, and do a good job of insulating the bottom of the board and the battery string connection terminals. DEFAULT setting fit for NCM/LFP battery, If you use for LTO battery, Please remove the previous short circuiting pad and then re short circuiting the LTO pad (with a rectangular short circuiting mark on the board).
- Working Voltage: 1.8V-4.5V, suitable for Li-ion,LiFePO4,LTO battery. The quiescent current is about 7mA, and the battery capacity is recommended to be used between 30-200AH/Per Balancer.High-capacity batteries can be connected in parallel with multiple equalizers. With under-voltage sleep protection, only detecting the B1 battery voltage, the equalizer will automatically stop entering the sleep state when B1 voltage NCM/LFP<2.7V or LTO<1.8V, and the standby power consumption is less than 0.1mA.
- Working Principle: Flying capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB. Balance current 0-5.5A, the more balanced the battery current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv!
