Lithium battery and lead-acid battery share wiring

Can lithium and lead-acid batteries be used together?

Both lithium batteries and lead-acid batteries are energy storage batteries, but they also rechargeable batteries with completely different characteristics, so they cannot be used together unless they can be used separately. , but must meet the technical requirements, including protective measures.

How do you wire a battery together?

There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.

Are lithium batteries more expensive than lead-acid batteries?

Under the same voltage and capacity, lithium batteries and Lead-acid batteries have the same cruising range, but lithium batteries are more than twice as expensive as lead-acid batteries; Lead-acid is significantly damage the environment due to its production process or discarded batteries.

How many volts is a lithium ion battery?

Each Lithium ion battery (LFP) cell is 3.2 V and 105Ah in capacity --> 3 in parallel is 315Ah and -->30 in series will 96V for the Lithium ion pack. And Lead Acid bank is 12V and 100Ah. Is there any fundamental disadvantage to this solution? The devil is in the detail and you haven't provided enough detail about the batteries and load current.

What happens if you mix a battery?

With no resistance to slow this charging process, the charged units can overheat as they rapidly drain and the discharged battery can overheat as it attempts to charge at well above its design capabilities. If you mix batteries of different ages – the older batteries will always have a lower voltage as all batteries self-discharge over time.

How do you wire a battery in series?

For more information on wiring in series see Connecting batteries in series, or our article on building battery banks. 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:
