rechargeable deep cycle batteries 12V 50ah screwable case lithium
batteries for rv
Features of LiFePO4 Battery:
- Longer Cycle Life: Offers up to 20 times longer cycle life and
five times longer float/calendar life than lead acid battery, helping
to minimize replacement cost and reduce total cost of ownership.
- Lighter Weight: About 40% of the weight of a comparable lead acid
battery. A 'drop in' replacement for lead acid batteries.
- Higher Power: Delivers twice power of lead acid battery, even
high discharge rate, while maintaining high energy capacity.
- Wider Temperature Range: -20 C~60 C.
- Increased Flexibility: Modular design enables deployment of up to
four batteries in series and max ten batteries in parallel.
Application:
- Electric vehicles, electric mobility
- Solar/wind energy storage system
- UPS, backup power
- Telecommunication
- Medical equipment
- Lighting
