About rechargeable lithium ion battery 11.1 v 4400mah

li ion battery 11.1 v 4400mah apply with high-quality 3s 18650 battery cells, the battery system come with built in PCM. Total energy 48Wh.

lithium 11.1v 4.4Ah battery structure.
The battery system build by 3S PCM. 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. The li-ion battery 11.1 volt 4400mah also come with ABS battery casing. Provide strong protection from any physical damage.

Safety and economical

Newest ICR18650 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.

Excellent discharge characteristics

11.1 volt  4400mah With low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field. Like UPS/Solar System/CCTV System/RF Power Meter

Long cycle life

Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.
