What are the key features of the 12V 90Ah LiFePO4 battery from Redway ESS?
This battery provides a nominal voltage of 12.8V and a capacity of 90Ah, storing approximately 1152Wh of energy. It supports continuous discharge currents up to 90A and peak currents around 180A. The battery is housed in a rugged ABS or metal casing with an IP65 rating for dust and water resistance. It weighs about 8 kg and measures roughly 306 x 168 x 211 mm. The integrated BMS offers protections against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes.
How does the Battery Management System (BMS) ensure safety and longevity?
The BMS continuously monitors cell voltages, current, temperature, and state of charge to prevent unsafe conditions such as overcharging, deep discharge, overheating, and short circuits. It balances cell voltages to maximize usable capacity and extend battery life. Advanced BMS versions provide Bluetooth and CAN bus connectivity for real-time monitoring and diagnostics.
Why is LiFePO4 chemistry ideal for reliable, high-capacity batteries?
LiFePO4 chemistry offers superior thermal stability, long cycle life exceeding 4000 cycles at 80% depth of discharge, and high energy density. It maintains stable voltage output, resists thermal runaway, and has a low self-discharge rate (~2-3% per month). Compared to lead-acid batteries, it is lighter, charges faster, and requires minimal maintenance.
What are the typical applications for a 12V 90Ah LiFePO4 battery?
Ideal for solar energy storage, recreational vehicles (RVs), marine vessels, off-grid power systems, backup power, and other applications requiring reliable, high-capacity, and long-lasting energy storage.
How do charging and discharging specifications impact battery performance?
The battery uses a CC/CV charging profile with a full charge voltage around 14.6V and a discharge cut-off voltage near 10V. It supports a standard charging current of 90A and continuous discharge current of 90A, with peak discharge currents up to 180A. These parameters enable fast charging and high power delivery.
