Knowledge base

Applications: Our products are used in hundreds of applications like electric vehicles, RV's, boats, cars, robots, telecommunications towers, Military and unmanned aerial vehicles, and much more. Our flawless track record of reliability, consistency, and quality is why we are the leading supplier of drop-in replacement lithium ion batteries worldwide.

Amp Hours: What many lead acid battery owners fail to realize is that its capacity (Ah) rating is usually specified at the 20 hour discharge rate. At high rates of discharge above 20A the usable capacity can be reduced to less than half due to "Peukert's Effect". A 225AH lead acid battery at an 80A discharge rate may only run for 53 minutes, whereas, a CHARGEX® 12V 225AH Lithium Ion Battery discharged at an 80A rate would last for almost 3 hours. When calculating amp hours with a CHARGEX® battery, you can use linear equations to size your battery bank. 

Significantly Less Weight: CHARGEX® Lithium Ion Batteries are about 70% lighter than the same size lead battery. 

Design: Our cells are bolted together to increase strength, conductivity, and quality design of our LiFePO4 batteries. The cells are bolted through length way circuit boards that provide additional strength, balancing, and short circuit protection. In the unlikely event one or more cells were to fail, the circuit boards will take that cell(s) off line and allow the battery to continue function normally at 12V with little reduced capacity. 

Cells: CHARGEX® batteries are built with 3.2V 5AH Cylindrical Lithium Ion Cells. Each cell is designed with explosion proof stainless steel, flame retardant electrolyte and a thermal fuse.

Consistency: Our 3.2V 5AH cells are mass produced with production capabilities reaching 500,000 cells per day.

Balancing:  Our cells are grouped together based on 10 consistencies when building each battery pack. The bolted cell design provides a stronger connection for less resistance and more current conductivity. Along with passive balancing through the lengthway circuit boards, these batteries maintain the highest overall pack capacity and are designed to last 3000 - 5000 cycles.

Charge Efficiency: CHARGEX® Lithium Ion Batteries are 99.1% efficient.

Rapid Charge: CHARGEX® Lithium Ion Batteries can be fully recharged from zero in as little as 1 hour.

No Voltage Drop: The voltage curve is nearly flat giving out higher voltage and power throughout the charge cycle.

Charge Algorithm: Our lithium batteries can be charged with a standard lead acid, gel, or AGM charger, however, we recommend using one of our chargers to get the best performance and longest life out of your CHARGEX® batteries.

Bulk, Absorb, and Float Charging: If your charger is programmable for different types of batteries you will want to choose either the “custom” or “AGM” setting.

No Self Discharge: Our batteries have little to no voltage drop and can hold a full charge for years. 

Orientation: CHARGEX® Lithium Ion Batteries can be mounted in any orientation. 

Vibration Proof: CHARGEX® Lithium Ion Battery cells are bolted together and made of solid construction. There are no fragile or brittle plates made of lead, which can be prone to failure over time as a result of vibration.

Higher Energy Density: CHARGEX® Lithium Ion Batteries have at least 4x higher energy density than lead batteries.

Capacity: Double the usable capacity of similar amp hour lead batteries.

Superior “Usable” Capacity: A CHARGEX® Lithium Ion Battery can be fully discharged down 100% without damaging the battery. Lead batteries typically only provide 50% usable capacity from the amp hour rating. This means that if your application requires 400 amp hours of usable capacity, you would have to size a lead acid battery bank of 800 amp hours.

Rated Capacity: CHARGEX® Lithium Ion Batteries have about 8% more capacity than rated (ex: a 100AH CHARGEX® Lithium Ion Battery can produce 108AH of usable capacity). 

Not Affected by Peukert's Law: Another huge advantage of CHARGEX® Lithium Ion Batteries is that Peukert's Losses are essentially non-existent. This means that a CHARGEX® battery can deliver its full rated capacity. 

Reliability: Thousands of CHARGEX® Lithium Ion Batteries are used all around the world for Commercial, Government and Military applications. Our proven technology and reliability has made us the Industry's Leading 12V Lithium Ion Battery Manufacturer.
