Pay attention to 6 issues of the use of lipo batteries

In the process of using lithium batteries, almost everyone will encounter these difficult problems. Here are 6 common questions for you.

  1. What type of battery should I use: 7.4V, 11.1V, 14.8V or higher?

You should check the ESC allowed input voltage in the ESC description. Your battery voltage must be in the ESC range.

  1. What do 12C, 15C and 20C mean?

The value of C (discharge rate) refers to the amount of electricity discharged by the battery and is related to the discharge limit of the LIPO battery. A high C value means that the battery has a high discharge load capacity, and a high C value also gives users a more explosive feeling when accelerating.

  1. Do I need to "balance" my LIPO battery?

Yes, if the batteries in the battery are unbalanced (or mismatched) with each other, they may not be used because such batteries are easily overcharged, overdischarged and may explode. A balancer can reduce this risk. Therefore, our LIPO will have a balanced platform or a balanced charging interface. You need to buy a charger with a balanced LIPO battery function. For the first time, you can use a balanced charger to charge a new battery directly. This can take a long time, but it can be better activated. The battery can achieve its best performance. For future use, you can use the discharge terminal to charge to about 4.1V, and then balance it with the balanced charging voltage, which can extend the battery life.

  1. Is a voltage limiter required in LIPO applications?

The limiter is actually a function that automatically cuts off the LIPO voltage used by the old ESC. Not LIPO.

When using LIPO to receive the battery, it is also compatible with the receiver. It is used to prevent the battery from being over-discharged during use during discharge, so that the battery can no longer be used.

The cut-off voltage of the battery is usually 6.25V or 3.0V per battery. As long as the voltage of the LIPO monolithic battery is below 3.0V, you may not be able to charge it.

  1. Does the battery need more time for maintenance?

It does not require more time, but it requires more care. Its maintenance is the same as ordinary LIPO batteries. But common sense is your best tool.

Unfortunately, tragedies often happen to those who do not pay attention and follow the rules of use set by battery manufacturers due to the abuse of LIPO and related disasters.

Examples of improper battery use include: running its motor at 80 ° C to overheat the battery; overcharging and overdischarging the battery under the wrong charging settings.

  1. Can I continue to use or repair the battery after the battery is damaged or mishandled?

If the LIPO has been completely destroyed or exceeds its recommended overcharge and overdischarge limits, and the battery has begun to swell, do not attempt to repair it.
