Can You Connect Batteries in Parallel With Different Amp Hours?
When you're building a battery banking concern for your mobile or off-grid application, it can exist tempting to mix and match different battery sizes. Simply put, the answer is NO.
For the longer caption on why this is a very bad idea, continue reading.
Mixing Bombardment Sizes: What Happens?
You cannot connect batteries of different amp-hours in series with practiced results.
We strongly recommend you Practise Non try to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.
This volition cause the highest voltage battery to accuse the lowest voltage bombardment attempting to create balance in the excursion. The greater the divergence in voltage, the higher the probability of battery failure.
Tin I Connect 100 Amp-Hour Battle Born Batteries to the 270 Amp-Hour Battle Born Batteries?
Here at Battle Built-in Batteries, nosotros offer two different lithium battery sizes: our 100 Amp-Hour BB100 series and GC2 series, and the new 270 Amp-hour batteries.
These two different sizes of batteries should never exist connected. Any attempt to connect Battle Born Batteries of different amp-hours will result in a voided warranty .
You should simply ever connect batteries of the same size.
How Practice I Connect Aforementioned Sized Batteries?
Y'all may use two unlike types of connections for batteries of the aforementioned voltage and amp-hours together to make a larger bank.
Proper Battery Connections
Parallel Connections – These connections are used when y'all want to increase the amperage of your battery bank. Nigh ordinarily, parallel-just connections are found in 12V systems.
The connections on this type of battery bank become from positive to positive and negative to negative. Connecting this way will double your amps (come across diagram below).
Series Connections – This type of connection is used when you need to increment the voltage of your bombardment bank. These types of battery connections are found in all types of battery banks including 12V, 24V, and 48V systems.
For instance, making a connection to the positive and negative terminals in this orientation is dissimilar than a parallel connection. Doing so links the batteries together increases the voltage of the battery bank (run into diagram beneath).
*If you plan to wire your batteries in serial, please permit us know when y'all place your order so we tin can make sure to lucifer your capacity.
Mixing Connections Vs. Mixing Bombardment Sizes
In some instances with a larger size battery bank, it is common to have series and parallel connections in your bombardment bank.
However, y'all should never exist connecting different bombardment sizes together in the aforementioned bank!
