LED light - quick check of charging status
Fast and stable charging of 36V lithium-ion batteries with charge control
The estimated charging time for a 36V battery is on average between 4 and 6 hours. The charging time for an e-bike battery depends not only on the charger’s power, but also on the battery’s capacity and current charge level. Charging will take longer if the battery is completely flat. Thanks to the built-in LED, you can easily monitor the charging process: red indicates charging, whilst green indicates that the battery is fully charged. You don’t need to worry about overcharging the battery – the electronics will ensure the process ends optimally. Once full charge is reached, the charger automatically stops charging and switches to standby mode.

Waterproof to outdoor conditions - IP54 standard

Protection against dust and splashing
The Qoltec charger is designed for everyday practical use - even in less favorable weather conditions. The device's housing meets the IP54 standard, which means that you can safely use the charger in the garage, under a carport, or even outdoors - without worrying about accidental splashes of water or dust.

How long to charge the 36V battery ?

Charge the battery regularly, avoiding it being completely discharged
If you want to enjoy a long battery life remember a few rules:

Charge the battery regularly, avoiding discharging it completely, preferably after every ride to keep it at 30-60%.

Avoid charging in extreme conditions as this will negatively affect battery life,

Avoid charging the battery at night as this leads to overcharging - cells, fully charged, will wear out more quickly,

We recommend charging the battery to 80-90%, a partial charge is preferable to a full charge as this will avoid overcharging the battery and save more time.
