What is the difference between a lithium and an AGM or lead-acid battery?

-

12.8V 50Ah 600Wh Deep cycle battery pack

1. Light weight, it is 1/3 weight of an equivalent traditional AGM or lead-acid battery.

2. Compact size, it is 1/3 size of an equivalent traditional an AGM or lead-acid battery.

3. Built-in BMS, a AGM or lead-acid battery is without any protection board, so it will have serious over-charge and over-discharge phenomenon, and even it will be dead if the battery is over-discharged to 0 voltage. But a lithium battery is built-in BMS, it can offer over-charge, over-discharge, over-current, over-voltage, over-temperature and short current protection.

4. Long life cycle, a LiFePO4 lithium battery is about 4 times as long as an AGM or lead-acid battery. A lithium battery has above 80% of rated capacity after 3000 times and above 45% of rated capacity after 6000 times, but an AGM or lead-acid battery is 200-300 times, and it is at most 400 times even it’s the best quality.

Cycle life is the number of times a battery can discharge and then fully charge.

5. Deep cycle, a lithium battery is deep cycle, it can be charged fully and discharged fully ,it can’t be damaged even it is discharged to 0v. But an AGM or a lead-acid battery just can be discharge 85% of its rated capacity, it will be dead if it’s over-discharged. For example, if you use a 12v lead-acid battery, it will be damaged when it is over-discharged to 10-9.5v, it will be damaged completely when it is over-discharged to 9.5v below. So a lithium battery will store more power ,you’ll get more charges out of it

6. High usable power capacity, an AGM or lead-acid battery should be charged when its left power is 30-40% of rated capacity , otherwise it is be damaged easily. But a lithium battery power can be used 100% of rated capacity.

So our lithium batteries are usually a drop-in replacement battery, That's what makes these batteries so much better than the older technology. Our lithium deep cycle range offer unrivalled performance over other batteries.


Is a lifepo4 lithium battery heavy?

A LifePO4 lithium car battery that can discharge about 100Ah will weigh around 11 - 13kg, while an AGM or lead-acid will weigh around 28Kg. Almost 1/3 the weight. A LifePO4 battery recharges faster due to its lower internal resistance and makes it a far better option for camping.


Is a lifepo4 lithium battery safe?

A question we're constantly asked is 'a lifepo4 lithium battery is dangerous?' Firstly a LiFePO4 batterie has low energy density, it is about 100-110wh/kg, but other lithium battery is 200wh/kg; secondly it has best heat stability, its internal chemistry starts to break down when its temperature reaches 500-600, but other lithium battery will break down when its temperature reaches 190-250; at last a lifepo4 battery uses a battery management system (BMS) ,so it can offer many protection functions. So our lifepo4 battery is  more evolved and modified for our harsh outdoor enviro

 

How do I recharge a 12v lithium battery?

Due to its low resistance, a lithium battery is easily and rapidly rechargeable using solar panels, AC and DC to DC battery chargers. Safe to use even on the hottest summer day with operational temperatures up to 80C. Lithium batteries are maintenance-free. They're so much better than lead-acid batteries that may be in your kit now.

How to Charge a Deep Cycle Battery in a Car?

-

Deep cycle batteries   are designed to provide a continuous flow of power over an extended period. Unlike starting batteries that deliver a quick burst of energy to start an engine, deep cycle batteries are built to withstand deep discharges and subsequent recharges. They are commonly used in car, marine, golf cart, and renewable energy applications. Steps to Charge a Deep Cycle Battery in a Car Step 1: Safety precautions Before attempting to charge a deep cycle battery, it's essential to take safety precautions. Make sure you are in a well-ventilated area, wear protective gloves and safety goggles, and keep any open flames or sparks away from the battery. Step 2: Assess the battery condition Before charging, inspect the battery for any signs of damage or leaks. Ensure the battery terminals are clean and free from corrosion. If you notice any issues, it's advisable to address them before proceeding with the charging process. Step 3: Determine the battery's state of charge T...

Lithium batteries replacing sealed lead acid in float applications

  It is extremely typical for lithium batteries to be positioned in an application where a shantytown battery used to be maintained on a floating fee. There has been some problem, whether this is secure for lithium batteries. It is usually appropriate to make use of a basic continuous voltage SLA charger with our lithium batteries, as long as it abides by particular requirements. As a side note, some clever or multi-stage shanty town battery chargers have an attribute that detects an open-circuit voltage (OCV). An over-discharged lithium battery that is in defense mode will have an OCV of 0. This type of charger would presume this battery is dead as well as would not attempt to charge it. A battery charger with a lithium setup will attempt to recuperate or "awaken" an over-discharged lithium battery. Long term storage space If you need to maintain your batteries in storage for a prolonged duration, there are a few things to think about as the storage space needs are various f...

How Does Car Start/Stop Technology Work?

Starting a car eats up more fuel than letting it idle for an hour. While cold starts tend to suck down a fair amount of gas when you first turn the ignition key, it’s the exact opposite when the engine is at optimal running temperature. This is why so many new car manufacturers are incorporating start/stop technology into their automobiles. The Society of Automotive Engineers ran a study that found that modern stop/start systems actually help increase fuel economy by over eight percent when running in heavy traffic. Over time, this can add up to a tremendous amount of fuel—and money—savings. Read on to learn more about how to stop/start technology works and one critical component of that system that uses more power than you may realize.   Start/Stop Technology While each car manufacturer has its own proprietary system, they all work very similarly. When you apply the brakes, and your car comes to a complete stop, the ECU cuts both fuel and spark, thereby instantly shuttin...
