Connecting lead acid batteries in series involves connecting the positive terminal of one battery to the negative terminal of another. This increases the overall voltage while keeping the capacity (ampere-hours) constant. For instance, if you connect two 12V lead acid batteries in series, you will get a 24V battery system.

Can You Mix AGM and Lead Acid Batteries?

For example, it''s not recommended to combine lead acid and lithium ion batteries within the same pack. Which is better lead acid or AGM? AGM batteries are better than lead acid batteries because they have a longer life, are more resistant to vibration, and can be discharged down to 20% without damaging the battery.
