Hi Drok,

I have three of your DC-DC converters and all work brilliantly thank you.

The smallest of the three Model 2001711006 specification says:
“4. Stop current flowing backwards protection at output terminal.”
I have used this converter to charge LiPo batteries successfully with the output of the converter directly connected to the battery.

I use Model 200310 to charge a 12V LiFePO4 battery bank from a 48V LiFePO4 battery bank. There is no mention of backwards protection in the manual and I have a schottky diode connected to the positive output before the 12V battery to prevent backwards current. It works in this manner, but obviously the voltage setting is different because of the diode. Is this diode required?

I also have Model 200150 which allows me to charge a 48V LiFePO4 battery bank from a 12V LiFePO4 battery bank. This is never connected at the same time as the above model 200310. Again, there is no mention of backwards protection in the manual and I also have a schottky diode protecting the output from backwards current. I understand this diode is required, but can you please confirm this?

If diodes are required, can I use MOSFET based ‘ideal diodes’ instead of schottky diodes?
I’m hoping without the schottky diode voltage drop, the voltage setting will be more accurate at the battery and there will be reduced losses through the diode. Is this ok?

Thank you,
Doug
