It has also set a record of selling over 6000+ units during the 15-day pre-sale period, receiving high praise from the market. Read on the LiTime 12V 100Ah vs LiTime 12V Mini LiFePO4 battery to know the details.

Features of LiTime 12V 100Ah Mini

Small in Size & Light in Weight

Compared to the typical 12V 100Ah version, mini has 35% smaller in size, 10% ligher in weight (only 19 lbs) but the same capacity.

Internal Structure

LiTime's 12V 100Ah Mini boasts an optimized internal design with a compact and sturdy structure, ensuring rock-solid reliability that has been rigorously tested and confirmed to be the safest ever. With this level of safety, you can confidently install the battery in any direction that suits your application, without worrying about any damage from rough roads or bumpy rides.

Note: Other 12V 100Ah LiFePO4 batteries can only be installed upright with post bolts facing up or on its 2 smaller sides.

Battery Cell

Unlike other batteries, the mini uses pouch LiFePO4 battery cells while others use prismatic LiFePO4 battery cells.

Pouch cells are flexible and lightweight, making them ideal for portable applications such as mobile devices and power banks. They are often used when space and weight are critical factors for the application. Pouch cells are also known for their ability to maintain voltage levels and discharge rates at lower temperatures.

This is one of the reasons why mini can be lighter and samller.

FAQS about LiTime 12V 100Ah Sereis LiFePO4 Battery

1. Can I connect classic 12V 100Ah and mini in series or parallel?

No. Connecting these two batteries together would be detrimental to their individual lifespans, as they possess differing cells and internal structures.

2. Can these batteries be used as starting batteries for golf carts?

No. All of LiTime 12V 100Ah series are deep-cycle batteries currently. Deep-cycle batteries are designed to provide a steady amount of power over a long period of time, whereas starting batteries are designed to provide a burst of power over a short period of time.

Using a deep-cycle battery as a starting battery could potentially cause damage to the battery and decrease its overall lifespan.

3. Can I charge them with a lead-acid battery charger?

Not recommended. It may not be fully charged when using the lead-acid battery charger. And we do not recommend long-term use, it will affect the performance and life of lithium iron phosphate batteries.
