    Making a 12V battery charger
  

*by A***L on Reviewed in India on 3 September 2020*

I made a 12V battery charger using 12V 300W DC-DC Power supply.Does it work? Yes whole setup works perfectly.Problem: I purchased various branded and unbranded battery chargers and all of them failed. Even Bosch C3 Battery charger didn’t last long. Every time a battery charger fail, I have to spend 2000-5000 Rs.Solution: Build a custom battery charger with Oil cooling. As I noticed most battery charger failed either due to electrical fluctuation or High temperature.For my design only thing susceptible for failure is DC-DC Bulk convertor. Using oil cooling setup I am trying to reduce the chances of failure due to temperature. We can always replace bulk convertor at around 500 Rs. So it’s very cost effective.My total component cost was about 2000 Rs. Planning took a day and building everything took another day.For more information explore the diagrams attached here with. I Purchased everything from Amazon.inEvery similar components DC bulk convertor, Booster, Mobile battery chargers are all the same, just different brand names and sold by different sellers.Please give up vote if you find this helpful. Have a nice day!Edit: It is still working after 2 years  (July 2022)

    Working as expected!
  

*by I***A on Reviewed in India on 3 November 2022*

Good product working as expected. Boosting current as voltage is stepped down.A cooling fan is recommended if it's used  for long time with more than 4amp current.But one thing is that the manual says it is 8A converter but in Amazon 9A is mentioned.So Amazon kindly correct it.Overall nice product 👍👌
