How to use the battery safely

The battery is one of the most frequently removed components when using an E-bike. There are quite a few issues in the daily use of the battery that deserve our attention. Maintain good battery use habits, which will help a lot with battery life and rider safety.

Please check device compatibility before charging

We recommend that all our riders use the official standard C3STROM charger (ASTRO/ASTRO PRO charger). This charger is a lithium-ion battery charger with an output voltage of 100-240V and is perfectly adapted to 52V ASTRO E-bike batteries. When there’s a situation where you have to use another charger to charge your battery, please check the output power of the charger carefully to confirm it is the same as the official charger.

However, we still do not recommend the long-term use of unofficial battery chargers to charge the battery, incompatible charging equipment will have a significant impact on the life of the battery, and there is also the possibility of battery damage due to incompatible equipment.

Safe charging procedure

Safe charging steps

When charging.

  • Plug the charger output into the socket
  • Connect the charger input to the AC power

To end charging.

  • Unplug the charger input from the AC power
  • Unplug the charger output from the socket

How to place the battery when charging

  • There should be no flammable or explosive items around the charger and battery.
  • The battery should be placed in a safe place where children cannot touch it.
  • The battery should be placed in a safe place that is ventilated and dry.

Charging abnormalities

Stop charging as soon as possible if any of the following abnormal conditions occur while the battery is charging.

  • Battery bulge
  • The battery emits a strange smell
  • Charging time exceeds the time limit and the green light is not yet on
  • The battery casing is damaged
  • Due to the different use scenarios, improper charging methods can cause the above problems, and if the power is not cut off in time, the battery may explode or catch fire.

Please do not charge in the open-air environment

Please do not charge the battery in the open air environment to avoid sudden rains that cause short-circuiting of the battery resulting in battery damage.

Charge the battery regularly

When you don’t use your E-bike for a long time, please charge the battery at least once a month to avoid battery power loss.

Regularly charging the battery for a short period can avoid damages caused by overcharging and transitional undercharging, and can effectively improve the service life of the battery.

Keep it at a certain temperature

It is recommended not to charge the battery at 7℉. This is because the C3STROM official battery has a low-temperature protection function. The normal temperature range for battery charging and discharging is 7℉~150℉. Above or below this temperature range, the battery may not be charged. Which is a new battery protection feature added by our technical team to protect the safety of our riders.

Also, when using the battery, when the temperature exceeds 150℉, the battery’s protection system will activate the over-temperature protection to cool down the battery to within 150℉.

When the outdoor temperature reaches 7℉, you can remove the battery and put it into a warmer and drier room for charging.

Storing the charger in a dry environment

Please keep the charger in a dry place and make an effort to keep rain and metal debris from getting inside. After a prolonged time of bumps, vibrations, and dampness, the charger will be easily destroyed if rain and metal particles penetrate.
