Battery size: 50.5*76.1*105.5mm

Battery internal resistance: ≤150mΩ

Battery weight: 1.2Kg

Charging current: less than or equal to 2.25A

Continuous discharge current: less than or equal to 9A

Protection current: 20A standard

Charging voltage: 29.2V

Discharge cut-off voltage: 20V

Discharge temperature: -20 ~ 60 °C

Storage temperature: -20 ~ 35 °C

Battery temperature protection: 70°C±5°C

·         PCM parameters: with single cell overcharge, over discharge, over current and short circuit protection. Specific requirements as follows:

·         single cell overcharge protection voltage: 4.22±0.25V

·         single cell overcharge recovery voltage: 4.15±0.50V

·         single cell over discharge protection voltage: 3.00±0.10V

·         single cell overcharge recovery voltage: 3.30±0.10V

·         over current threshold (10ms): 70A

·         charge balance current: 50±10mA

·         charge balance voltage: 4.18±25mV

·         battery temperature protection scope (recoverable): -20-60?

·         short circuit protection on battery pack.

·         Battery capacity monitor system function: with smart chip and LCD screen, monitor system could timely set display parameters, including battery current capacity, current capacity percentage, current battery voltage, charge current, discharge current, discharge remaining time, RSOC and ASOC.

·         Battery overall structure design: due to wide distribution area of cell phone tower and outdoor environment, insulation, damp-proof and ageing& deterioration proof should be considered on battery. Hence, glass plate and plastic bracket could be used as case body of lithium battery pack.

·         Secondary protection: the whole battery is equipped with protection fuse to prevent short circuit from abnormal over current. In the event of PCM system abnormity, fuse could cut off output circuit of the whole battery pack.

·         Lithium battery cell: use Japan original imported cell, 18650 lithium battery cell /2500mAh/3.7V, which has good safety and consistency to ensure reliability of the whole battery pack.
