Customize Any of The Following Battery Packs as Required
Can be customized according to the requirements of 3.7V, 7.4V,
11.1V, 14.8V, 18.5V, 22.2V, 25.9V, 36V, 48V, 60V, 72V
Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.
| NO | Items | Criterion | Condition |
| 1 | Internal Impedance | ≤20mΩ | Test the internal resistance of 50% SOC battery pack with 1 kHz AC
internal resistance test instrument. |
| 2 | Capacity | ≥100Ah | Rest for 1 hour after fully charged, then discharge with 0.33C
current until the battery reaches the discharge cutoff voltage.
Repeat above process for three times, if the discharge time is not
less than 180 minutes, you can stop and define the Discharging
current*time value (Ah) as battery capacity. |
| 3 | Short circuit protection | / | Not allowed. |
| 4 | MAX charge Current | 80A | Charging with this current for more than 0.5h and the added
temperature of battery pack less than 20℃. |
| 5 | MAX discharge Current | 100A | Discharging with this current for more than 0.5h and the added
temperature of battery pack less than 35℃. |
| 6 |
Cycle life (DOD%100) | ≥2000cycle | Discharge with the current of 0.5C until it can’t discharge, and
then rest it for 1h. Charge the battery following
CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h.
Repeat above process until full charged capacity is no more than
80% of normal value. Accumulated times is defined as cycle life. |
| 7 |
Discharge Temperature Characteristics | -20℃ | ≥70% | At 25±5℃ discharge the battery with the current of 0.33C to the
cut-off voltage. Store the battery at various temperatures for 2h
and discharge the battery with 0.33C to the cut-off voltage. Record
the ratio between discharging & charging capacity. |
| 0℃ | ≥80% |
| 25℃ | 100% |
| 55℃ | ≥95% |
| 8 | Charge Retention ability | remain capacity≥90% | Charge the battery to full capacity and store it for 28days, and
then discharge it with 0.33C to the cut-off voltage. |
Circuit Protection
The batteries are supplied with a LiFePO4 Battery Management System
(BMS)that can monitor and optimized each single prismatic cell
during charge & discharge, to protect the battery pack overcharge,
over discharge, short circuit. Overall, the BMS helps to ensure
safe and accurate running.
| Test item | Content | Criterion |
| Over charge | Over-charge protection for each cell | 3.80±0.03V |
| Over-charge release for each cell | 3.60±0.05V |
| Over-charge release method | Under the release voltage |
| Over discharge | Over-discharge protection for each cell | 2.00±0.05V |
| Over-discharge release for each cell | 2.30±0.05V |
| Over-discharge release method | Charging |
| Over current | Discharge over current protection | 350~550A |
| Protection delay time | 10~40ms |
| Over current release method | Release after cutoff the load. |
Over Temperature | Battery over temperature | Protection @65±5℃ |

Applications:
Golf trolly of 12v 1200w motor , Wireless camera, surveillance
cameras, wireless infrared detector, car LCD TV, portable DVD,
personal treatment system, PDA personal data assistant, personal
communications systems, walkie-talkies, digital cameras,
camcorders, video cameras, Bluetooth devices, CD players, MD
players, MP3 players, smart cards, aviation model LED lights and
other fields can be used in 12V power.
Features:
The battery uses original brand ion batteries, with a small
internal resistance, big capacity, cycle times and more, no memory
effect, etc; internal circuit for multiple protection design, can
prevent over charge, over discharge, over current; production
process quality inspection and monitoring the use of computers to
ensure superior battery performance.
How to choose a suitable battery pack?
- battery voltage is the same with the original.
- battery size same with the original. Or similar/smaller.
- battery plugs same with the original (check the plug diagram)
Match the above three conditions, in general, this battery can be
used.
The larger of MAH, the longer use time. Different voltage, battery
size, shape, can be same voltage, because the battery combination
of different ways, the shape is not the same. You can leave a
message about your old battery, please pay attention!!!
