12v 300ah lithium ion battery apply with high-quality 4s lithium iron phosphate, the battery system come with built in BMS, possible for high power amps discharge. Total energy 3600Wh. This battery pack with built in LED or bluetooth function to monitor battery state.
high power 12v battery system build by 4S BMS. can effectively charge and discharge the battery pack . The BMS prevent any battery overcharge, over discharge caused by damage, And can control the battery charge, discharge current, Ensure that the battery pack and applications are not damaged；To ensure that in the event of a short circuit failure when the output off and automatic balance of the application of the battery pack at any time in the best condition. high capacity rechargeable 12v battery build with a metal casing. it provids strong protection from any physical damage.
If you are fan of DIY. This is the right site you are in. CMX also provide high Qaolity A grade prismatic 300ah and 310Ah large capacity LiFePo4 cells. Here for more details of the cell. Simply make your own battery pack with our large capacity LiFePo4 cells.
Built in Bluetooth easy to monitor the battery from mobile phone anytime. The high capacity 12v lithium ion battery with LiFePo4 battery cells. Battery cell is tested before assemble. It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons it’s safe for household use.
high capacity 12v battery With low internal resistance and high, flat voltage characteristics during strong current discharge, possible working in high temperature environment. which ensures a wider application field. Like outdoor UPS/Solar System/marine/lithium rv system.
12v 300ah lithium ion battery with long storage and long life cycles. It offers problem-free charge after long storage, permitting to use in a wide range of applications.
How long does it take to charge a smart battery 12v 300ah lithium ion battery
Just same like most of other rechargeable batteries. a 12v Lithium ion battery charging voltage is 12.6v if NCM cells inside. While if the battery form by LiFePo4, then it is 4 in series. Charging voltage is 14.6 volt. Charging time all depending on the Charger output current. For example, if we use a 12v 100A charger. Means we can fully charge the 12v 300 amp hours by 3 hours. If use a 12v 50A charger. we can fully charge it by 6 hours.
