Our portable DIGI MARKER 12.8V 45Ah (With 50A BMS) Lithium-Iron Phosphate LifePO4 Battery provides off-the-grid power supply for 4WD vehicles, caravans, campers, trailers, motor-homes, marine applications, and all 12.8V appliances including portable fridges and washers. The 45Ah 12.8V battery features an incredible cycle life of up to 5000 cycles, making it one of the most enduring in its class. What you get is a longer, consistent and more drawn out charge all the time. The integrated smart battery management system (BMS) not only protects this 12.8V 45Ah LiFePO4 battery from various abnormal conditions but monitors and manages the charging/discharging process. The state-of-the-art battery cells ensure a long cycle life and exceptional discharge performance. The maintenance-free deep cycle battery is completely sealed, spill-proof and does not leak gas for added safety and durable use. Lithium-Iron Phosphate battery is smaller and generally weights less than half of what comparable lead acid battery does. Less stress during installation, and less strain on wherever you end up installing it. Invest in this sealed, maintenance-free battery for your off-grid system today!
About our Battery's BMS
The unique built-in Battery management system (BMS) of our products lithium Battery can protect it from overcharge, deep discharge, overload, overheating and short circuit, and low self-discharge rate. Our BMS has a high temperature disconnect function. When the internal temperature of the battery reaches 75℃ ( 167°F ) it will automatically disconnect to protect the battery. With overcharge and over discharge protection functions, when the overcharge voltage exceeds 15V or the over discharge voltage is lower than 8.8V, the battery will automatically disconnect. Our recommended charging voltage and discharging voltage are 14.6±0.2V and 10v±0.2V, respectively. If the charging voltage is lower than 13.8V, the battery power (with a deviation of 1-2°/o) cannot be fully charged.
About our Battery's cell
Lithium-ion Batteries have high energy density and high average output voltage, The self-discharge is small and there is no memory effect. The wide operating temperature range is -20℃ - 60℃. Excellent cycle performance, fast charging and discharging, charging efficiency up to 100%, and high output power, long service life. It does not contain toxic and hazardous substances and is called a green battery.
About the parallel and series of our Batteries
Our Lifepo4 batteries can be connected in parallels and in series for larger capacity and higher voltage.
We suggest that:
1. The Max connection in series is: 4 Batteries to 48V
2. The Max connection in series/in parallels: Support 4 series and 4 parallel (in the case of simultaneous series and parallel connection)
3. The Max connection in parallels is (In the case of separate parallel connection, no series connection): it can connect multiple batteries, and no more than 10 batteries in parallel.
Products of different manufacturers and different capacity batteries cannot be connected in series or in parallel. When the batteries are used in parallel or series, the voltage must be the same. It can support fast charging and solar panel charging.
