I purchased a 200Ah battery, and the seller told me that the instantaneous current of the 200Ah battery reaches 900A before it will activate the protection of the power failure, I asked about the safety issue, they told me not to worry, this battery also has high temperature protection and short circuit protection, it will also cut off when the operating temperature exceeds 65 degrees Celsius! I asked about the safety issue, they told me not to worry, this battery also has high temperature protection and short circuit protection, the battery working temperature exceeds 65 degrees Celsius will also cut off the power! Multiple protection rocks are very safe! The battery is now mounted on a ride-on toy and is flying happily!
