Running 24V on two 12V batteries

Click For Summary
SUMMARY

Connecting two 12V batteries in series to achieve 24V is feasible, but it is crucial to avoid simultaneously connecting them in parallel. The discussion highlights the need for a suitable converter, specifically a 12V to 24V converter capable of handling a maximum of 50 amps. The alternative option of using a 24V battery with a 12V to 24V 20-amp converter for charging from a 12V alternator is also presented, but the series connection remains the preferred method for achieving 24V.

PREREQUISITES
  • Understanding of battery configurations (series vs. parallel)
  • Knowledge of voltage conversion techniques
  • Familiarity with alternator charging systems
  • Experience with electrical load calculations
NEXT STEPS
  • Research 12V to 24V DC-DC converters with at least 50 amps capacity
  • Learn about battery management systems for series configurations
  • Investigate the specifications and installation of 24V batteries
  • Explore the implications of using alternators with different voltage systems
USEFUL FOR

Electrical engineers, automotive technicians, and hobbyists working on custom battery systems or power supply solutions.

Hi, can I connect two 12v batteries in series to get 24v and also each battery has individual connectors connected to 12v alternator from engine for charging? Would this cause problem?

Or what type of converter (if there is one) that can do 12v to 24v with max. 50amp.

Another option I just thought of is maybe a 24v battery but with a 12 to 24v 20amp converter to connect the 12v alternator to charge 24v battery.

Which option would work better?
Thank you.
