The Upower 12.8 V \/ 50 Ah battery is a high performance monoblock, designed to provide an energy storage solution that is efficient, durable and safe.<\/p>\n
Thanks to its lithium iron phosphate technology (LiFePO\u2084), this battery has a long service life and is virtually maintenance-free.<\/p>\n
It is widely used in caravans, tour buses, electric vehicles such as motorbikes and bicycles, emergency lighting, security systems and other equipment requiring reliable power.<\/p>\n
The Upower battery has a nominal voltage of 12.8 volts, a usable capacity of 50 amps, a discharge capacity of 100A and 640Wh of usable stored energy.<\/p>\n
Its cycle life is over 2,500 cycles at 100 % discharge (DoD), which means it lasts up to 10 times longer than many lead-acid batteries.<\/p>\n
In addition, its discharge curve is almost flat, so the voltage remains stable for almost the entire cycle, ensuring constant power even with demanding loads.<\/p>\n
The Upower battery is designed as a single block with lithium iron phosphate (LiFePO\u2084) cells, which give it high thermal and chemical stability, greatly reducing the risk of overheating or premature failure.<\/p>\n
In addition, it is configured in four cells in series (4S) and four in parallel (4P), offering balanced and safe performance.<\/p>\n
The Upower 12.8V\/50Ah has an integrated battery management system (BMS), which optimises the battery and automatically balances the charge of the cells, protecting it from overcharging and over-discharging.<\/p>\n
This ensures greater durability and safer, more uniform cycles.<\/p>\n
The Upower battery can operate in a wide range of temperatures, both charging (0 \u00b0C to 45 \u00b0C) and discharging (-20 \u00b0C to 60 \u00b0C), making it suitable for both indoor and outdoor use.<\/p>\n
For storage, it is recommended to keep it between -10 \u00b0C and 35 \u00b0C.<\/p>\n
This battery has protections against overcharge, over-discharge, over-current, short circuits and extreme temperatures, extending its life.<\/p>\n
In addition to an IP65 degree of protection, it includes several protections, such as high temperature thermal fuses, flame retardant additive and pressure relief valves, for added safety.<\/p>\n
Its monoblock format allows for easy installation.<\/p>\n
In addition, this battery is maintenance-free because it does not require ventilation, electrolyte recharging or periodic servicing.<\/p>\n
This Upower battery is ideal for a wide variety of uses, including:<\/p>\n
