When Lesser Heat arrives, midsummer truly begins.  

"Lesser Heat arrives, midsummer begins." The ancients said, "The hottest days are in the dog days of summer," and the prelude to those dog days starts right with Lesser Heat. The wind carries the chirping of cicadas, the asphalt shimmers with waves of heat, and even the air seems baked to a tipsy warmth. The days of July burn hot, and all living things thrive in this heat—yet people just want to find a patch of shade and steal a moment of coolness.  

And you—every day, you ride that two-wheeled or three-wheeled e-bike through the city's streets and alleys. Delivering orders, commuting, picking up the kids, buying groceries—it travels the longest roads with you and carries the heaviest loads. Under the scorching sun, the seat is too hot to sit on, but you still swing your leg over, twist the throttle, and plunge straight into the heat.  

But have you ever wondered—that "heart" hidden beneath the seat, the one that runs with you every day—that lithium battery—is it still doing okay?  

In extreme heat, batteries have a harder time than people do.  

After a full day parked under the blazing sun, the internal temperature of the vehicle can easily exceed 50°C. If you then go home after work, plug in the charger, and start charging right away, the battery's internal temperature can spike straight past 70°C. Once or twice, you might not notice, but every single instance of "charging in high heat" quietly chips away at the battery's lifespan. Some calculations show that capacity degradation in high-temperature environments is three times faster than at normal temperatures. In other words, every time you let your battery "get heatstroke," it answers back with shorter range.  

It doesn't speak, doesn't complain—it just silently delivers its power so that you arrive at every destination on time.  

You probably haven't noticed how long that battery has been with you. Charged and discharged every day, through wind and rain—it never complains. It bears the summer heat and endures the winter cold. Unlike a smartphone, it doesn't flash a warning that says, "Temperature too high—please cool down before use." It just sits quietly under the seat—until one day, you realize that even with a full charge, you're only halfway through your trip when the low-battery alarm goes off. That's when you know: it's tired.  

And what Pucoon Technology wants to do is to make that "tiredness" come later—much later.  

We use brand-new Grade-A cells, sourcing the finest quality fresh cells from the very start, held to the highest standards. Every single cell undergoes strict matching to ensure consistent internal resistance, voltage, and capacity. Paired with our self-developed intelligent BMS (Battery Management System), we monitor the temperature and status of every cell in real time. When abnormal high temperatures occur, the system actively reduces current to protect the battery, guarding against overcharging, over-discharging, short circuits, and other risks.  

A truly reliable lithium battery shouldn't just look good in lab data—it should deliver that steady, dependable power the moment you twist the throttle, on every blazing noontime, so that you arrive at every place you want to go, right on time.  

As Lesser Heat brings the heat, take good care of yourself. Wear your helmet when you head out, drink plenty of water, and don't push yourself too hard under the sun. And take care of your battery too. Park in the shade whenever possible, and wait about half an hour after riding before you plug it in to charge—don't let it suffer "heatstroke" along with you. After all, it still has to take you to many more places—through the next midsummer, through autumn, through yet another winter, until every "destination" becomes a new "starting point."  

May Lesser Heat treat you well, and may peace and reassurance accompany you wherever you go.
