Bolted Together For Superior Strength
Chargex Lithium Iron Phosphate Batteries are manufactured contrastingly superior from the competition with our bolted 32700 Stainless Steel Cylindrical LiFePO4 Battery Cells.
Each cell is bolted through a rigid lengthway circuit board that strengthens the battery pack and provides superior current conductivity compared to tab welded cells. Chargex lithium battery packs are held together with thick, solid copper bus plates that prevent the pack from bending or warping in extreme conditions further maximizing current conductivity and strength to the battery pack.
Built Tough, Safe, and Dependable
The Chargex Battery Management Systems (BMS) sets itself apart with top tier MOSFETS and electrical components for maximum efficiency, performance, and reliability. Our BMS modules typically have higher charge and discharge current capability than competitor lithium batteries with the same capacity, this allows you to use our batteries for both deep cycle and starting applications.
Each BMS has standard features including short circuit protection, reverse polarity protection, low voltage, and over voltage protection. Chargex BMS modules vary across battery models, typically we do not add temperature features that can prevent you from using the battery in low temperatures, while this may reduce the life cycle of the battery, it allows you to keep running your Marine, RV, and electronics regardless of the temperature.
Lengthway Circuit Boards
Chargex Lithium Battery cells are bolted together through Lengthway Circuit Boards that provide rigid strength to the battery pack and connect to the BMS that balances individual cells.
The Lengthway Circuit Boards will shut down an individual cell in the unlikely event of failure preventing short circuit and allowing the rest of the battery to continue functioning normally, if a single cell fails with a tab welded battery pack, it can short circuit and will cause the whole pack to fail. Other lithium batteries are typically built with tab welded cells that are balanced together as a string of cells.
The 32700 3.2V 5AH LiFePO4 Lithium Iron Phosphate Battery Cell
Chargex batteries are manufactured with 32700 - 3.2V Lithium Iron Phosphate (LiFePO4) Explosion Proof Stainless Steel Cells. Every cell is bolted together for a firm connection and more electrical conductivity compared to the tab welded method.
Each cell has a unique built-in thermal fuse that in the unlikely event a cell is overheating, internally disconnects shutting down the cell and preventing it from overheating. In addition, a high pressure safety vent and flame retardant electrolyte make this one of the world's safest batteries.
- Explosion Proof
- High Quality Stainless Steel
- Thermal Fuse
- Flame Retardant Electrolyte
- Hight Pressure Safety Vent
Chargex is a division of our lithium battery engineering group founded in 2010. After 13 years' accumulation, growth and experience, we have developed into one of the industries leading battery manufacturers with offices, sales teams, and factories located around the world. In 2010 we pioneered plug and play, drop in replacement batteries for consumer applications, now, along with building customized battery solutions for telecom, (ESS) Energy Storage Systems, EV and industrial applications, our focus has shifted to supporting aerospace and defense projects, namely, with the US Naval Surface Warfare division, NASA-JPL, BOEING and the US Air Force. Chargex headquarters is located in Tampa, Florida with a sophisticated R&D engineering team for complex, integrated lithium battery systems.

CHARGEX® EnergyWave
Heavy Duty Battery Protection System
This highly advanced internal battery protection system automatically turns the battery off if it's drained below 8V or charged above 16V - preventing accidental over discharge. The Battery Protection System will turn off the battery by sensing a short circuit, reverse polarity, over and under voltage, as well as, over current. This Built-in Battery Protection System maximizes the efficiency and performance of the battery to increase its cycle life.

Our firm uses the 12V 100AH Group 31 Lithium Ion Battery in over 40 fleet vehicles and we love them. Currently we have to change out 3 batteries per vehicle every 6 - 8 months due to heavy amp draws our equipment placed on the lead batteries. The Lithium Battery is designed to handle these heavy loads without sacrificing life of the battery, we are expecting over 5 years in our vehicles that would require over 6 sets of lead batteries to last as long as one set of lithium batteries. Eliminating maintenance and downtime of our equipment. We also considered the environmental impact of switching to lithium batteries from lead acid batteries knowing the lithium batteries are non hazardous we are reducing our carbon footprint and getting a much better battery at the same time.

I required a high quality lithium battery to run electrical equipment and for emergency back up power. These guys were able to assist us in determining the best battery to use based on the power requirements should we experience a power outage. Having a reliable and practical solution is important to keep our systems running in the event of a power outage. Lead acid batteries are hazardous and cannot be used in our factory due to safety concerns with off gassing, Lithium ion batteries were the best option and finding this company was a quick and easy solution for us.

I am an artist and travel in my RV along with my wife Dawn and our dog Lucy. We are often camping off grid and run our lights and inverter off our lead batteries which would only last for a couple hours running lights and our TV. Our generator auto start turns on is very noisy so we were researching better lead acid batteries for our coach when we came across Lithium Batteries at an RV show in Florida. The benefits of lithium ion batteries vs lead batteries for our coach seemed like an obvious choice considering how much off grid camping we do. Our coach formerly required 4 - 6V lead acid batteries, The rep at their booth explained we only needed two of there 12V batteries to connect in parallel and that would replace all 4 of our 6V lead batteries due to the lead batteries not being able to be drained more than 50% of their rated capacity, leaving us with 50% unusable dead weight (literally). We decided to go ahead and purchased 2 - SB100 lithium batteries and have been happy we did. Our coach has enough battery power to run our lights and TV as long as we need and have not turned off on us yet. When we camp in cold areas the batteries keep our heater running all night whereas before our generator would cut on in the middle of the night to recharge the lead batteries. We absolutely love the batteries and recommend them for anyone looking to upgrade Their coach batteries.
