Li-ion, Li-NMC, LiFePO4 Battery Cells

Battery cells are the foundation of any power system—from drones and robotic platforms to electronic warfare systems (EW), energy storage units, and portable devices. The market offers dozens of form factors — 18650, 21700, prismatic, pouch — but one thing matters most: rechargeable batteries provide stable energy for your electronics.

Among the solutions we offer are Li ion, Li-NMC, and LiFePO4 cells from leading brands like Samsung, Molicel, Lishen, and EVE. Buy power cells with proven quality and reliability, trusted in military and engineering applications.

Battery Cell Applications

Power supply is needed everywhere — from household electronics to high-tech military systems. Thanks to a wide range of chemistries (Liion, Li-NMC, LiFePO4) and form factors, these cells allow you to build custom battery packs with the required capacity, voltage, and current — tailored to your project's needs.

Our rechargeable batteries are chosen to create solutions such as:

• FPV drone batteries — compact size, low weight, and stable voltage, which are crucial in flight;
• batteries for quadcopters and aircraft — high discharge currents and durability under load;
• power systems for EW and SIGINT — stable performance and chemical safety are essential;
• power modules for UGVs (unmanned ground vehicles) — high cycle life and durability;
• backup power systems where capacity and lifespan are key.

These cells form the basis of complete batteries and are used in the products featured in the following categories:

• “Batteries for FPV drones”
• “Batteries for UAVs and aircrafts”
• “Batteries for EW and SIGINT”
• “Backup power batteries”

All battery cells are sourced directly from manufacturers — no intermediaries. Each batch undergoes double quality control to ensure reliable specifications, safe use, and consistent performance.

Battery Cell Types at BTRY ENERGY

We offer battery cells in three main chemistries: Li-ion, Li-NMC, and LiFePO4 3.2v. Each has its own benefits, use cases, and technical specifications.

Li-ion (21700): Maximum Power and Energy Density

Li-ion 21700 cells are the optimal choice for battery packs that require compact size and stable discharge under load. At BTRY.ENERGY, you’ll find:

1. High-discharge cells:
   • Lishen LR2170LA – a solid balance between capacity and current;
   • Molicel INR21700-P42A – one of the best cells on the market for extreme discharge rates;
   • Samsung INR21700-50S – high capacity and reliable performance under load.
2. Low-discharge cells:
   • Lishen LR2170SZ – designed for long-lasting operation at medium current levels.

These cells are used in our battery packs: 6s2p, 6s3p, 6s4p, and 6s6p for drones, quadcopters, and aircraft.

Li-NMC: Stability and Density in a Slim Format

SK Innovation E603A is a pouch-type Li-NMC cell that we use for EW and SIGINT battery packs — ideal for applications requiring high energy density, reliability, and stable operation during long missions. Based on this cell, we’ve developed battery packs in the following configurations:

1. Standard:
   • 7s1p;
   • 6s1p;
   • 6s3p;
2. Custom:
   • 7s1p BAT.053 V1;
   • 7s1p BAT.095;
   • ENERGY MODULE – a cluster system with automatic switching and “hot-swap” functionality.

LiFePO4: Lifespan, Safety, and Reliability

For applications where cycle life and safety are top priorities, we offer EVE LF105 and LF280K cells. EVE LiFePO4 chemistry is a great choice for backup power systems, infrastructure projects, and long-term deployments.

These cells are used in energy supply solutions, mobile hubs, and backup battery systems — combining long service life with safe operation.
