12V 45Ah LiFePO4 Deep Cycle Lithium iron lightweight trolling motor battery BMS

  
About our Digi Marker Battery. Introducing our portable DIGI MARKER Lithium-Iron Phosphate Battery, a reliable off-the-grid power supply for a range of applications including 4WD vehicles, caravans, campers, trailers, motor-homes, marine use, and 12V appliances like portable fridges and washers.

This Lifepo4 battery boasts an impressive cycle life of up to 4000 cycles, ensuring long-lasting and consistent power. Equipped with an integrated smart Battery Management System (BMS), it provides protection against various abnormal conditions while monitoring and managing the charging/discharging process. The advanced battery cells deliver exceptional discharge performance and extend the overall cycle life.

Completely sealed and spill-proof, this maintenance-free deep cycle battery prioritizes safety and durability. Compared to traditional lead-acid batteries, our Lithium-Iron Phosphate battery is smaller and weighs less than half, making installation stress-free and minimizing strain wherever it is installed.

Invest in this sealed and maintenance-free battery today to power your off-grid system with confidence! Our lithium battery products feature a unique built-in Battery Management System (BMS) that provides comprehensive protection against overcharging, deep discharge, overload, overheating, and short circuits.

Additionally, our BMS ensures a low self-discharge rate. It incorporates a high-temperature disconnect function, automatically disconnecting the battery if the internal temperature reaches 75°C (167°F) to safeguard its integrity. The BMS also includes overcharge and over-discharge protection mechanisms, disconnecting the battery if the voltage exceeds 15V during charging or drops below 8.8V during discharging.

For optimal performance, we recommend a charging voltage of 14.6±0.2V and a discharging voltage of 10V±0.2V. Please note that charging the battery below 13.8V may result in incomplete charging, with a deviation of 1-2%. 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. 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. Q: Why choose Digi Marker battery over others? A: Higher energy intensity lighter weight compared with AGM or lead-acid battery 100% real capacity, each has been factory inspected. Q: Are Digi Marker Battries waterproof?

A: All of our Digi Marker LiFePO4 battery has an IP65 protection class, which sets you free from worrying to install it indoors or outdoors. But when charging or discharging the battery, please be careful not to let the post bolts or terminals come into contact with water, as this may damage the battery. Q: Can the battery be installed horizontally?

A: Yes, the Digi Marker ithium battery can be installed in any position as it does not suffer from safety issues like battery leakage or corrosion, commonly associated with lead-acid batteries. Q: Do I need a special charger for this battery?

A: You can use an AC-to-DC lead-acid charger that is mains-powered, but it should not have automatic desulfation or equalization modes. These modes can risk damaging the cells or the battery itself. It is recommended to use a charger with a simple bulk/absorption/trickle charge profile and disconnect it after charging, avoiding leaving it in trickle charge/maintenance mode. Q: Will the battery have enough power upon arrival? If you exhaust the initial 30% power, you can recharge the battery using solar panels or utility power.

Q: Is my device compatible with your batteries? A: Digi Marker battery can serve most of the normal devices if use the battery correctly under the instructions of the manual. If you're unsure whether your device is compatible with our batteries, please consult the load devices manual and verify if it supports the continuous charging and discharging current and power specifications of our batteries. Please carefully read the product manual before installation and use, ensuring correct battery usage as instructed. Ensure proper polarity: Never reverse the connection of the positive and negative terminals of the battery to avoid damage or malfunction.

Handle with care: Avoid knocking, throwing, stepping on, or subjecting the battery to physical impact, as it can cause internal damage and compromise its performance. Avoid direct metal contact: Never use metal objects to directly connect the positive and negative terminals of the battery, as it can lead to short circuits or damage to the battery. Avoid excessive heat or punctures: Do not directly solder the battery or pierce it with nails or sharp objects, as it can cause damage to the battery cells and pose safety risks. Prevent water immersion: Never immerse the battery in seawater or water, as it can lead to damage, corrosion, or electrical hazards. Not suitable for car starters: Do not use the battery as a car starter, jump starter, or engine starter battery, as it is not designed for such high-current applications. Avoid high temperatures: Do not use or place the battery in high-temperature environments, as it can lead to overheating, fire, malfunction, and reduced lifespan. HOW TO ACTIVE THE BATTERY. If the battery cannot be charged and the voltage is too low this is the time to activate. If the BMS has cut-off the battery for protection, you need to cut off the load of the battery and put the battery aside for 30mins. Then the battery will automatically recover itself to normal voltage and can be used after fully charged. If the battery is unable to recover itself and its voltage is too low to hold a charge, you can activate it in below ways.

Use the charger with 0V charging function(it can charge the battery starting from 0V) to charge the battery. After fully charged, the battery can be used normally. Use another 12V lithium battery to connect in parallel with the battery for a minute to activate the battery. (lead-acid battery with voltage more than/equal to 12V and less than/equal to 14.6V will also work).

After that, fully charge the battery and it can be used normally. Use an 18V solar panel to directly charge the battery so that the current does not need to pass through the controller and the BMS can be activated. You also can use a 12V solar panel to activate the battery's BMS, it takes about 3 seconds to fully activate. 12V 45Ah LiFePO4 Battery Pack 1. Please be noted: battery charger is not included.
