Wide Applications

The long battery life and high durability, low weight and current parameters are the reasons why these batteries are used in leisure vehicles and campers and in photovoltaics providing power to homes using solar panels.

 

【Automotive Grade Lithium Battery】

12V 300Ah Lithium Batteries have superior quality since it is manufactured by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power. Highest-level safety based on UL Testing Certificate for the LifePO4 battery. 12V 300Ah Battery supports max. 3.84kWh usable energy, it is 3 times energy and running time than a 12V 100Ah battery directly. 

【Up to 6000 Cycles】

LiFePO4 Batteries provide up to 6000 cycles, which depends on your actual using depth of discharge (4000 cycles at 100%DOD, 6000 cycles at 80%DOD, 10000 cycles at 60%DOD). It is more than 20~30 times to Lead Acid with 200~500 cycles. LiFePO4 battery has a 10-year service life, which is longer 3 times than the Lead Acid Battery’s 3-year lifetime. 

【1/3* Lightweight】

12V 300Ah LiFePO4 Battery weighs only 26.3kg, compared to lead-acid batteries, lithium battery provides 56Wh/lb energy density, and only 1/3* the weight of the lead-acid battery, which makes it easier to install or move. It is a perfect upgrade for any 12V Deep Cycle battery. This makes Lithium batteries perfect for solar homes, RVs, campers, motor homes, and off-grid applications.

【Flexible Capacity Expansion】

Battery can be connected in parallel and series for larger capacity and higher voltage. The 12V 200Ah battery supports up to 4 identical batteries for up to a 48V 300Ah battery system in series or a 12V 1200Ah battery system in parallel. That also can be connected to 16 identical batteries(4P4S) to a 48V 1200Ah battery system, which supports max. 40.96kW load power and 61.44kWh energy. Various combinations make it more flexible to use.

【100% Protection】

Battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuits with ultra-low self-discharge rate. Built-in high-temp cut-off prevents charging over 167 °F (75 °C). Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. battery is IP65 level waterproof, which set you free from worrying to install indoors or outdoors.
