"The balcony at 3 a.m."

Father frowned beside the old electric tricycle:

"The battery can't be charged again... I have to deliver vegetables to the market tomorrow morning."

"The next morning"

Daughter handed over a new battery box with a protection board:

"Dad, this time it will accompany you to withstand 3,000 sunrises."

—— We believe that the warmth of technology is to make important people no longer worry

Core Value

"It is more afraid of battery damage than you are"

When overcharged, it is like a mother protecting a hot pot: "Stop! It's full!"

When short-circuited, it is like a father repairing a fuse: "With me here, sparks can't run wild!"

"Batteries quarrel? It will be the peacemaker"

Are the voltages of the 7 cells uneven? Quietly "cooking special dishes" for the weak and "stepping on the brakes" for the strong
Result: The whole family goes out with all the electricity in order, just like the slippers you put in place
"Time can't steal the youth of the battery"
Ordinary batteries decay by 30% in one year, but the batteries it manages can still say "I can still do it!" after 5 years
(Actual test: with balancing function, cycle life ≥ 2000 times)

Family protection moment
Sending children to the emergency room on a rainy night
The electric car ran wildly in the rain, and the protection board silently pressed the overcurrent: "Go steadily, don't cut off the power."
Grandpa's fishing energy storage box
The sun by the lake was baked to 50℃, and the protection board started the "cool heart" mode: "High temperature? I block it!"
The store's freezer backup power supply
The power outage on the typhoon day, the protection board gritted its teeth and held on for 8 hours: "The ice cream didn't melt, it must be done!"
Son's remote control racing car
The child reversed the wires and smoked, and the protection board instantly shut down: "Don't be afraid, Dad can't fix it, I'll save it."
"Its heart is like a Swiss watch"
120A high current = Power 10 air conditioners at the same time without taking a breath
Seven-layer protection = 7 layers of bulletproof vests for the battery, bullets from "overcharge" to "reverse connection" are fully protected
20℃ cold resistance = more resistant to freezing than polar bears, electric vehicles can be turned on in winter

User testimonials
Auto repair shop Lao Zhang:
"The board installed last year, jumping around every day to repair cars for others, and never entered my shop!"
