Now, we linked the battery to a 3000W (peak) pure sine wave inverter and to the inverter,we linked twoheaters as loadand set a present draw near 20A (19.6A) as this is the same as 0.2C. We attached a battery tester with a shunt to watch the battery parameters. The battery voltage was round 13.3V and with a load drawing 19.6A, the overall energy draw (mixture of heater and the inverter) was roughly 260W.
The over-discharge safety of the BMS kicked in and shutoff the output when the battery voltage fell to 10.3V though the specs say discharge cutoff voltage as 10V. The battery tester confirmed the capability as 99.04Ah and whole vitality as 1268Wh. That is simply 1% lower than the rated capability of the battery, which is suitable.
Now, we charged the battery utilizing the 20A lithium battery charger. It took nearly 5-1/2 hours to completely cost the battery. The open circuit voltage of a fully-charged battery was 14.3V.
We as soon as once more carried out a discharge take a look at however this time, we set the discharge present to about 40A (for a 0.4C discharge) by connecting a bunch of heaters and blower followers. The whole energy draw from the battery was roughly 524W.Even this time, the capability reported by the battery tester got here at 99.08Ah, which has similarities to the earlier take a look at.
Should you have a look at the specs of the GOLDENMATE12V 100Ah LiFePO4 Lithium Battery, it says the cost temperature vary is 0°C to 50°C, the discharge temperature vary is -20°C to 60°C and the storage temperature vary is 0°C to 45°C. Whereas exploring the heart of this battery, we observed two temperature sensors and thought one is for overheat safety and the opposite is for low temperature safety.
To check this, we linked the charger and whereas the battery is charging, we sprayed some freeze spray on the tip of the temperature sensor to immediately scale back the temperature of the sensor. As anticipated, the BMS shutoff the charging immediately. Very good to see low temperature safety being applied in “new” manufacturers.
An necessary level to recollect in regards to the GOLDENMATE12V 100Ah LiFePO4 Lithium Battery is it’s not a SLI Battery or Starter Battery. So, in case your intensions are to interchange your automotive battery with this, then it is not going to work.
