LiFePO4 Prismatic Battery Module 3.2V 156Ah for Solar Systems, Safe and Scalable

Meet the LFP-3.2V-156Ah LiFePO4 battery module from Tewaycell — a robust, safe, and scalable energy solution for solar-powered systems in RVs, boats, and off-grid installations. Each module uses prismatic LiFePO4 cells with a nominal 3.2V per cell and a generous 156Ah capacity, delivering reliable power with a long life cycle. The compact aluminum shell keeps weight and space in check while offering strong durability for demanding environments. This battery is designed to be configured in common pack arrangements (4/8/16/32 cells) to meet different voltage and capacity requirements, making it adaptable to a wide range of solar PV, mobile, and remote power applications. Note: EU US Tax Free.

Benefits & Tips

• High safety and longevity — LiFePO4 chemistry provides stable performance, high cycle life, and enhanced safety for demanding off-grid power needs.
• Flexible configurations — Configure in 4/8/16/32 cell blocks to tailor system voltage and capacity for your solar, RV, or marine setup.
• Efficient and reliable — Low internal impedance supports stable charging and discharging, while wide operating temperatures keep performance consistent from -20°C to 60°C. Use with an appropriate BMS to maximize longevity.
