FAQ

Due to logistics restrictions, the battery has only 25~30% SOC before leaving the factory. We recommend that the battery be fully charged before use, and the battery voltage will return to normal.

If you have just received a new battery or the battery has not been charged for a long time, the battery SOC in the APP may be inaccurate. The SOC will be accurate after a week of full charge and discharge.

1. When the battery enters "under-voltage protection", please fully charge the battery (because the battery is large, charging will take a certain amount of time to fully charge).
2. If you still cannot fully charge the battery, please consider whether the charger does not match the problem.
3. If the above situation occurs, please contact Kanavano official customer service for consultation.

1. Connect old and new batteries in series and parallel. Generally speaking, as long as the voltage difference between the new battery and the fully charged old battery does not exceed 0.15V, both old and new batteries can be connected in series and parallel. We recommend confirming the battery voltage difference between the old and new batteries after they are fully charged before connecting them in series and parallel. Generally speaking, batteries purchased within three months can be connected in series and parallel. Because we currently cannot confirm the specific batch number of the current battery before shipment, we cannot accurately confirm whether the batch number of the battery you are currently purchasing is the same batch. Batteries from the same batch can definitely be connected in series and parallel. If you need to connect batteries in series and parallel in the future, please fully charge each battery separately and confirm the voltage difference before connecting in series or parallel.
2. Standard batteries can be connected in series and parallel with preheated batteries. We don't recommend this. When the cold weather is below 0°C, the preheated model can be charged, but the standard model cannot be charged. If two batteries are connected in series or parallel, the battery system will work abnormally.

Since the cable size is affected by factors such as cable length, cable current, inverter power rating, etc., you must check the total power consumption of the total power system and the operating voltage of the battery system (such as 12V/24V/36V/48V battery system) First, then the current in the battery system can be roughly calculated. Finally, refer to the Cable Sizes table in the Welcome Guide to select the appropriate cable size. You can also ask us for more advice on cable sizing.

The battery has a built-in BMS, which can protect the battery from overcharge, over-discharge, over-current, short circuit, and high-temperature environment.

If the battery enters low temperature protection and you want to restore the battery temperature as soon as possible, it is recommended to place it at least in a place with an ambient temperature above 20°C, so that the battery core temperature should be able to recover to a temperature above 0°C within a few hours. But if the ambient temperature is lower than 10°C, it will take at least half a day for the battery to resume charging.

1. Some chargers cannot activate our batteries. It is recommended to use Kanavano chargers. How to determine whether the battery can activate the battery, please send the charger model to Kanavano customer service.
2. If you use a solar charger to charge the battery, please make the charging parameters of the solar charger consistent with the settings in the manual.
