Dayi's 48-volt lithium battery can be fitted with a 20-watt LED bulb.
Since 2010, certain lamps can even replace higher wattage bulbs. For example, a 13 watt light bulb has about the same brightness as a 100 watt incandescent lamp. Typical efficiency standards for warm incandescent lamps are around 14 to 17 lumens/watt, depending on their size and voltage. According to European standards, an “energy saving bulb” equivalent to a 60 watt incandescent lamp must be able to produce at least 806 lumens.
Deep and long-term charging of lithium batteries:
Long-term charging of lithium batteries can cause overcharging. Lithium batteries or chargers automatically shut off once the battery is fully charged. There is no so-called “maintenance” charge that lasts more than 10 hours with battery chargers.nickel battery.
Lithium Battery If your lithium battery is fully charged, it will be charged in vain if you put it on the charger. And none of us can guarantee that the characteristics of the battery charge and discharge protection circuit will never change and the quality is foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long recharges.
