solar energy systems, RVs, marine applications, and backup power
setups.
With a robust nominal voltage of 12.8V and a large capacity of
250Ah, this battery supports continuous charge and discharge
currents up to 200A, ensuring dependable performance even under
demanding loads. Its compact dimensions and lightweight design
(approximately 21 kg) make installation and transport simple and
hassle-free.
Equipped with a high-quality JBD/DALY Battery Management System
(BMS), the Redway 12V 250Ah battery offers comprehensive protection
against overcharging, overheating, and short circuits, ensuring
maximum safety and longevity. It operates efficiently across a wide
temperature range—from 0°C to 60°C for charging and -20°C to 65°C
for discharging—making it versatile for diverse environments.
This battery supports up to 6 units in parallel, enabling scalable
energy solutions tailored to customer needs. Optional upgrades such
as Bluetooth monitoring, GPS tracking, self-heating, and LCD
display provide enhanced functionality. Certified to international
standards including UL1642, IEC62619, CE, and UN38.3, 12V 250Ah
Lithium Battery guarantees safe, reliable power for your customers.
