In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
Here’s a detailed comparison of batteries in parallel versus series: Parallel Configuration: Voltage: When batteries are connected in parallel, the overall voltage remains the same as the voltage of a single battery. For instance, if you connect two 12V batteries in parallel, the total voltage remains 12V.
Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.
for secondary (rechargeable) batteries – the stronger battery would charge the weaker one, draining itself and wasting energy. If you connect rechargeable batteries in parallel and one is discharged while the others are charged – the charged batteries will attempt to charge the discharged battery.
In actual practice, people put lead acid batteries in parallel and cycle them that way frequently. Just look at RV's and boats and off-grid installations. A fuse for each battery would not be a bad idea. If you are charging them all anyway then what does it matter if one discharges into another?
When batteries are connected in parallel, their positive terminals are connected to each other, and their negative terminals are also connected. This setup maintains the same voltage as a single battery but increases the overall capacity (amp-hours).
Here''s a detailed comparison of batteries in parallel versus series: 1) Voltage and Capacity. Parallel Configuration: Voltage: When batteries are connected in parallel, the overall voltage remains the same as the voltage of a single …
For example, connecting two 12V batteries in series results in a total voltage of 24V. Capacity: The total capacity remains the same as the capacity of one of the individual batteries. Two …
When you connect two batteries with different voltages, you''ll have a current $I=frac{Delta V}{2*R_{int}}$, assuming both batteries have the same internal resistance. If …
Note, when you parallel batteries, you should have a fuse/breaker per string to prevent a short on one battery string from being feed by the other string--this does add wiring/costs to parallel …
