51v 105Ah lithium golf cart battery

OSM Golf Li+ design for 48v golf cart, with nominal voltage 51 volt , are special design for electric golf cart. And it adopts the latest Lithium iron phosphate technology. With our own designed High quality BMS and LFP prismatic cells, the product has the features of the fashionable design, high energy , high power density, long service life, and easiness of installation and expansion, all of which reflect the real requirements of the end users and strongest technical capability of our company.

It is a kind of environmentally friendly backup power system. We use phosphates rather than cobalt to avoid environmental concerns, lower the possibilities of thermal runaway because of improper disposal, and save the production cost as well. Compared with other products in the market now, this kind of product experiences a lower rate of capacity loss.

We are Original Battery Factory in China Focus On LiFePO4 Battery Solutions, Welcome to contact us If You Have Individual Pricing for Large Scale Projects And OSM Wholesale.

BMS Protection of 48v golf cart batteries

OSM-gf48100 is deep cycle golf cart batteries for electric golf cart . This battery is equipped with a BMS protection circuit plate, which can monitor the running state of the battery in real time, provide protection such as over-charge, over-discharge, over-current, short circuit,over-temperature and equalization when necessary, and cut off the input and output of the battery for protection.
OSM™ lifepo4 battery 48 100ah have installation flexibility, fast-charging capabilities and are maintenance free.

FAQ:  How long to golf cart batteries last?

105Ah can run it for 10 Hours. If the discharge current is 10Amps. Battery capacity is rated in ampere hour (abbreviated Ah, or sometimes amp hour). It is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour.

Testing of OSM  battery

golf cart battery inside golf cart battery manufacture












golf cart battery testing

cell testing












Test based on 51v 105ah lithium ion deep cycle golf cart battery – OSM-gf4810.The test conducted at a temperature of 25±5 ℃, relative humidity of 45% ~ 75%, and atmospheric pressure of 86kPa ~ 106kPa. Room temperature as mentioned in this specification refers to 25±2 ℃.

(1).Standard Charge:

At indoor temperature, the golf cart battery pack is first discharged to the cut-off voltage with a current of 40A, and then charged to 13.8V with a constant current of 40A, and then charged in a constant voltage charging mode. The battery pack is stopped charging when the charging current drops to 0.01C, and then shelve for 1h after charging.

(2).Standard Discharge:

At indoor temperature, the OSM-gf48100 is first charged in the standard charging mode. After charging, the golf cart battery pack is discharged to the cut-off voltage with a discharging current of 40A. After discharging, the battery pack is shelved for 1h.

Test Conditions
Battery Resistance
≤ 100mΩ
Measure with 1kHz AC internal resistance tester at 50% SOC of the battery.
Battery Capacity
105Ah ± 5%
Charge and discharge in standard charge and discharge mode, and record discharge capacity.

Charge Retention

The discharge capacity is maintained no less than 85% of the rated capacity
fter standard charging, the battery shall be shelved for 28 days under ambient temperature of 25±5 ℃, and the discharge capacity
shall meet the test requirements at room temperature with 0.2C continuous discharge current to the discharge cut-off voltage.
Discharge recovery capacity is not less than 90% of the rated capacity
Then after standard charging again, and discharge to the termination voltage with 0.2C continuous discharge current at the ambient
temperature of 25±5 ℃. The discharge capacity should meet the test requirements.
