What Really Occurs When Lithium Batteries Are Paralleled? Uncovering Voltage and BMS Dynamics

Imagine two water buckets connected by a pipe. This is like connecting lithium batteries in parallel. The water level represents voltage, and the flow represents electric current. Let's break down what happens in simple terms:

Scenario 1: Same Water Level (Matched Voltage)

When both "buckets" (batteries) have identical water levels:

* Charging (adding water):Current splits evenly between batteries
* Discharging (pouring out):Both batteries contribute power equallyThis is the ideal and safest setup!

Scenario 2: Uneven Water Levels (Voltage Mismatch)

When one bucket has higher water level:

* Small difference (1V):Water rushes violently to the low bucketBasic protection shuts down the connection

Scenario 3: Different Bucket Sizes (Capacity Mismatch)

Example: Small battery (24V/10Ah) + Large battery (24V/100Ah)

* Same water level (voltage) required!
* Discharging at 10A:Small battery supplies ~0.9ALarge battery supplies ~9.1A
* Key insight: Both water levels drop at same speed!

NEVER Mix These!

Different pump types (discharge rates):

* Strong pump (high-rate battery) pushes too hard
* Weak pump (low-rate) gets damaged quickly
* Can cause overheating or fire!

3 Golden Safety Rules

* Match water levels: Check voltage with multimeter (difference less than or equal to 0.1V)
* Use smart faucet: Choose BMS with parallel current control

* Same bucket type:

* Identical capacity
* Same chemistry (e.g., both LiFePO4)
* Matching pump power (discharge rate)

Pro tip: Parallel batteries should behave like twins!
