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? 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). Solar system + Wind Power system. Fire alarm and security systems.
Electric equipment and telemeter equipment. Portable power tools measuring and medical equipment. Wireless lawn movers vacuum cleaner. Portable video camera portable personal computer. Camper Trailer Caravan Camping Truck Bus RV etc.
Can be connected in parallel. Can be connected in series (up to 4). Heavy duty Removable M8 Bolt Battery terminals. Built in battery management system for safety protection.
Battery management system enclosed, no extra wiring needed. Built with LiFePO4 battery cells that are engineered to deliver superior performance&longevity.
Perfect replacement or upgrade for a traditional lead-acid battery. Connect in Series: Up to 4 identical batteries for up to 48V. This battery does not have a low temperature heating function. Please do not charge the battery in a temperature lower than 32°F 0?
To avoid damage to the battery. 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.
