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? Excellent cycle performance, fast charging and discharging, charging efficiency up to 100%, and high output power. 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.

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. 150A (Duration: less than 5 seconds).

2, Discharge Temperature : -4°F -20? 3, If it is a 4-string lithium iron battery pack, the charge protection voltage is 3.65v=14.6v, and the discharge protection voltage is 2.5V4 = 10V. How to charge the battery?

Scheme 1: You can use a lithium iron phosphate 4-string(14.6V) charger to charge the battery pack. Scheme 2: You can use photo voltaic solar panels to charge the battery through MPPT. Scheme 3: You can use the inverter to charge the battery pack(note: the inverter needs a built-in AC to DC charging function). NOTE: It is recommended to set the 12.8V lifepo4 battery controller (MPPT) or inverter discharge cut-off voltage to 10.8V.

In this way, MPPT can give priority to the protection of the battery and extend the service life of the lifepo4 battery. (25.6V lifepo4 battery controller /MPPT or inverter discharge cut-off voltage to 21.6V). 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. These two steps are necessary in order to reduce the voltage difference between batteries, and through these, the battery system can perform the best of it in series or/and in parallel.

Fully charge your batteries separately. Connect your batteries one by one in parallel and leave them together for 12-24hrs. And then, you can connect your batteries in series or/and in parallel. Please read the product manual carefully before installing and using the product.

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.
