FAQS 4

Can you mix different capacity lithium batteries?

Yes, you can mix different capacity lithium batteries, whether a normal 12V 100Ah battery or a Lithium server rack battery. You can combine different capacity batteries in parallel. You cannot combine different capacity batteries in series. There are a few points you need to consider when wiring in parallel. Let’s explore these three points.

How to choose a lithium battery?

Replace all batteries when they run low. Use a lithium battery protection plate with corresponding parameters. Select batteries with consistent performance. Generally, lithium battery cells need to be paired for serial and parallel use. Pairing criteria: voltage difference ≤10mV, internal resistance difference ≤5m ω, capacity difference ≤20mA

What is the difference between lithium battery series and parallel?

Lithium batteries in parallel: the voltage remains the same, the capacity is added, the internal resistance is reduced, and the power supply time is extended. Lithium battery series and parallel: Both parallel combination and series combination are in the middle of the battery pack, which increases the voltage and capacity.

Are series and parallel connection of lithium batteries safe?

The series and parallel connection of lithium batteries is a key technology to increase voltage and capacity, but it also contains safety risks. This article will analyze in detail the principles, methods and precautions of series and parallel connection of lithium batteries to help you avoid potential risks and build a battery system correctly.
