Bestgo offers the "Preferred" series lithium ion battery packs to suit different kinds of applications. The chemistry of the battery pack consists of Lithium Iron Phosphate (LiFePO4) which is the safest li-ion battery. All battery packs are equipped with aluminum cases for strength and safety. They are light in weight, reliable in strength, with good thermal conductivity. They are also attractive in appearance with a rounded corner shape.
These Preferred battery packs are sealed to meet IP66 protection level so they can be used in many harsh conditions. To realize this design, Bestgo uses the most advanced cells which can offer superior performance that will generate much less heat than other competitor’s products. The Preferred packs feature passive cooling without a fan.
However, if the battery packs need to offer continuous high-power input and output (like within 2 hours charging from empty to full, or discharging from full to empty in 2 hours), and the surrounding temperature is high, please consider offering some air cooling or liquid cooling method to keep the battery pack within a reasonable temperature. If the battery pack is not overheated, it will have a long life.
The Preferred packs have handle(s) for lifting and carrying. In addition, they have an intelligent indicator to show the voltage, current, SOC and capacity etc. Red and black terminals with M8 screw holes build on top lid for power cable connection. There are 3 screw holes on each long side of the battery pack. Each screw hole has a size of M4*8. They can be used to fix the battery pack with bolts. Screw holes do not affect IP level as the end of hole is totally sealed.
Specifications:

Battery
Pack Weight: 89 Lbs. (40.5 Kg)
BMS
and Fuse: PCB BMS and fuse are built inside case. The fuse is 250A slow type.
Rated
Capacity: > 200 Ah at C/3, 73°F (23°C) (Measured as 2.5V cut off at cell level)
Operating
Voltage: 25.6 V (average) at C/3, 73°F (23°C); Working voltage range is 29.2 ~
20.8 V
Charging
Voltage: < 29.2 V at CC/CV charge mode (Can be charged to 28.8V for longer
cycle life.)
Discharge
Cut Off Voltage: 20 ~ 20.8 V (When any cell's voltage reaches 2.5V this
protection will be triggered) (Set device (like a controller) low voltage protection
much higher to avoid triggering this protection.)
Maximum
Charge Current: < 100 A at 60 min, 23°C, 20%< SOC <70%; < 200 A at 5 min, 23°C, 20%< SOC <70% (Please consider heat accumulation inside pack if charging with a large continuous current.)
Maximum
Discharge Current: < 200 A at 30 min, 23°C, 30%< SOC <100%; < 400 A
at 15s, 23°C, 30%< SOC <100% (Please consider heat accumulation inside pack if discharging with a large continuous current.)
Battery Cycle Life: > 3000 times at 80% DOD, C/3, 23°C (After test it can deliver > 75% rated capacity.)
Internal
Resistance: 10 milliohms (DCIR test method, at 10s, 50% SOC)
Temperature
protection for charging process: 0 ~ 5 °C < Sensor for cell < 65 ~ 70 °C (If inside sensor detects a temperature that is outside of range, the BMS will shut the pack off.)
Temperature
protection for discharging process: Sensor for cell: < 65 ~ 70 °C (If
inside sensor detects a temperature that is outside of range, the BMS will shut the pack off.)
Surrounded
working condition temperature: Charge: 41 ~ 113°F (5 ~ 45°C); Discharge: -4 ~
131°F (-20 ~ 55°C) (Suggested for charging: 50 ~ 104°F (10 ~ 40°C); Suggested
for discharging: 14 ~ 113°F (-10 ~ 45°C)
Storage
Temperature: 14°F ~ 104°F (-10°C ~ 40°C) (for < 3 months) Keep SOC at 40~60%
for long term storage.
Note: Inside the battery pack, the temperature sensors are attached to both the cells
and the BMS. However, the temperature measurements are not very accurate. As a result, the BMS may
trigger protection in a specific temperature range. Due to a passive
cooling design which does not have a fan for cooling, please consider the heat
accumulation inside the pack. When in a hot temperature please do not charge or
discharge the battery pack with a big constant current, it may trigger
temperature protection.
