parallel
You can coarsely determine their state of charge by measuring their quiescent voltage -- i.e. their voltage when you haven''t tried charging or discharging them in the last few hours.. Lead-acid batteries (and, well, a lot of batteries) become less charge-efficient as they get nearer to top-of-charge. As such, if they are reasonably near, they will tend to self-balance.
Charging Two Batteries in Parallel: Your Ultimate Guide
Understanding Battery Basics Before we begin parallel charging, let''s cover some battery basics. Batteries store electrical energy and come in two main types: lead-acid and lithium-ion. Lead-acid batteries are common and cost-effective but are heavier and less efficient for deep cycling.

3. Battery bank wiring
If a large battery bank is needed, we do not recommend that you construct the battery bank out of numerous series/parallel 12V lead acid batteries. The maximum is at around 3 (or 4) paralleled strings. The reason for this is that with a large battery bank like this, it becomes tricky to create a balanced battery bank.

6 FAQs about [Dual lead-acid batteries in parallel]
Can a lead acid battery be connected in parallel?
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.
What is a series parallel battery?
There is series-parallel connected batteries. Series-parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system. For example, you can connect six 6V 100Ah batteries together to give you a 12V 300Ah battery, this is achieved by configuring three strings of two batteries.
What is a parallel battery connection?
Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity. With a parallel battery connection the capacity will increase, however the battery voltage will remain the same.
Can a lead acid battery be voltage charged?
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.
How do parallel batteries work?
The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
Do you need a fuse for a lead acid 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?
