The answer is yes, you can use mismatched batteries in parallel as long as they are the same type and voltage. However, there are a few things to keep in mind when doing so.

So what is the difference between these, and why would a designer require a couple big D cell batteries for a flashlight when a couple AAA have the same voltage rating? There are two
They suck in charging power at different rates, and the biggest is still pulling in power while the small ones have been pretty much balanced (and quit) at full charging voltage. (When the current drops to near zero, I quit on the charger.) My batteries are only 4s, but nearly the same size yours (one at about 60Ah, another at 105Ah, and the biggest at 120Ah). Yeah,
First of all, assuming solid connections, the voltage across each battery will always be the same. What does that mean? Let''s suppose you have 3 different 12V batteries, wired in parallel to supply 12V power to your RV. They can have different capacities on account of size or age, but the same chemistry (e.g. all flooded lead acid or all AGM).
A battery has internal resistance, that can be viewed as an "invisible resistor" wired sequentially with the voltage source. This resistance restricts the charging and discharging current and is smaller for the powerful battery.
Different Types of Batteries and Their Voltages. Batteries come in various forms, each suited to specific applications and characterized by distinct voltage ranges. Understanding these types can help you choose the right battery for your needs. Common Battery Types. Alkaline Batteries: These are the most common household batteries, like AA and AAA,
It''s generally recommended to use batteries with matching capacities and matching voltages when connecting them in series and/or in parallel to ensure optimal performance and longevity. Overall it''s technically possible to connect imbalanced batteries together, but the capacity mismatch can lead to performance issues a
Batteries in parallel have to be the same size but don''t have to be the same voltage. You can use different voltages in parallel, as long as the total voltage of all the batteries is within the range that your device can handle. For example, if you''re using four AA batteries in a device that requires 6-8 volts, you could use two 3-volt batteries and two 1.5-volt batteries. As
The voltage of a battery is not always equal across different batteries. In fact, it is quite common for batteries of the same type to have slightly different voltages. This variation in voltage is due to several factors. Firstly, the voltage of a battery is determined by the electrochemical reactions that occur inside it. These reactions
Yes, you can put different size batteries in parallel as long as they are the same type of battery. For example, you could put two 9-volt batteries in parallel to create an 18-volt power source. However, if you put a 9-volt and an AA battery in parallel, it will not work because they are different types of batteries.
Take two LiFePO4 batteries, even at different states of charge but at the same voltage. What happens if you initially parallel them? Answer: nothing. They''ll just sit there, both with their own BMS. Now you provide a charge source. Both batteries will start charging but one will take more charge current than the other even at the same state of
First of all, assuming solid connections, the voltage across each battery will always be the same. What does that mean? Let''s suppose you have 3 different 12V batteries,
You should not connect different batteries in parallel. If you do, the battery with the highest voltage will discharge into the other one, until they end up with equal voltages. If the second battery (the lower voltage one) is a rechargeable, then it will be charged by the first one, again until the two have the same voltage.
You can safely have different "Packs" within a Battery Bank. A pack being an independent battery pack of cells with t''s own BMS. A Bank being the collection of packs assembled into a large power storage bank of batteries. Packs in Series increase voltage, Packs in Parallel increase Amp-hours.
Take two LiFePO4 batteries, even at different states of charge but at the same voltage. What happens if you initially parallel them? Answer: nothing. They''ll just sit there, both with their own BMS. Now you provide a
If you wanted to compare batteries with the same amount of energy but different voltages then you might compare a 12V 100Ah battery, a 24V 50Ah battery, and a 48V 25Ah battery. All three of those have the same energy, weigh the same, and cost the same. Or consider if you were building a battery. You might buy 16 3.2V 100Ah battery
1 Amp and 2 Amp chargers for a given battery type will produce the same final voltage, but the 2 Amp charger can deliver a higher currrent into a discharged battery. With both chargers, the actual charging current will decrease as the battery approaches full charge.
How do different batteries with the same voltage differ? While batteries with the same voltage may seem similar, they can actually differ in terms of capacity, chemistry, and
How do different batteries with the same voltage differ? While batteries with the same voltage may seem similar, they can actually differ in terms of capacity, chemistry, and internal resistance. For example, a lithium-ion battery with the same voltage as an alkaline battery will typically have a higher capacity and lower internal resistance
When there is no load current, the voltages of both of our batteries are the same. Open circuit voltages. Let''s gradually increase $I_{load}$. The voltage of the battery with higher $R_{series}$ will be falling more, and it will fall out of spec at a smaller current than that of a battery with lower $R_{series}$. _____ ** Battery is a
1 Amp and 2 Amp chargers for a given battery type will produce the same final voltage, but the 2 Amp charger can deliver a higher currrent into a discharged battery. With both chargers, the
A battery has internal resistance, that can be viewed as an "invisible resistor" wired sequentially with the voltage source. This resistance restricts the charging and
I have been running multiple batteries of different voltages in series with no issues what so ever. It''s all in the technique and extra steps required to successfully run different voltages in series. I currently run 84v on
Check this with a voltmeter or you will experience problems (covered in connecting batteries of different voltages in parallel above). It is for these reasons that you are advised to use batteries of the same brand, voltage and capacity. Failing to do so (if you don''t have the knowledge and tools to check what you are doing) could create a potentially
If you wanted to compare batteries with the same amount of energy but different voltages then you might compare a 12V 100Ah battery, a 24V 50Ah battery, and a 48V 25Ah
So what is the difference between these, and why would a designer require a couple big D cell batteries for a flashlight when a couple AAA have the same voltage rating? There are two main reasons. One is the total energy contained (a D cell is larger in volume, and thus has more room to store chemical energy, and thus can run a device longer

Let’s suppose you have 3 different 12V batteries, wired in parallel to supply 12V power to your RV. They can have different capacities on account of size or age, but the same chemistry (e.g. all flooded lead acid or all AGM). Before you start charging, the voltage across each of them is the same–even if one is fully charged and the others aren’t.
They can have different capacities on account of size or age, but the same chemistry (e.g. all flooded lead acid or all AGM). Before you start charging, the voltage across each of them is the same–even if one is fully charged and the others aren’t. Charge will flow from one battery to the other two until they’re balanced.
However, when connecting batteries of different capacities in parallel, the batteries will not discharge or charge at exactly the same rate. The battery with the higher capacity will contribute more to the total energy storage, while the battery with the lower capacity may reach its limits sooner.
Experts say "current depends on voltage". So, if the voltage is high, current would be high. Agreed; (I = V/R) If the voltage is low, the current would also be low. Agreed -> I = V/R
Yes, imho it can. (imagine charging a 1.5 V battery with a 12 V supply..) ( : You should not connect different batteries in parallel. If you do, the battery with the highest voltage will discharge into the other one, until they end up with equal voltages.
The people designing other stuff promise to pull less than some maximum current from the battery as long as the voltage applied is in the normal operating range. When these promises are violated, the convenient simple rules of thumb we use ("batteries put out a constant voltage") don't work anymore.
