ip67 abs case
plastic abs shell, waterproof design, effectively ensure the safe use of the
battery pack in harsh and humid environments such as fishing boats and ships.
industry's first structural design of precision stainless steel fasteners
inside the battery box, which is fixed, sealed, and tightened by screws, which
is convenient for disassembly and maintenance; effectively protects the heavy
cells and the precise bms circuit board from shaking, and the battery box and
the internal cells and bms motherboard. Tightly connected and integrated, it is
not affected by the vibration of shipping and freight transportation, and in
the later use, along with ships and electric fishing boats, the long-term
movement of the rv will not affect the structural loosening and performance.
battery with top notch brand of bms to protect, it has low temperature cut off
protection, it means that when people charge the battery below 0°c, the bms
will automatically cut off and stop charging. Bt connect smartphone and monitor
battery at any time all parameters and indicators operate safely.
Battery characteristic curve
With a 100 amp continuous current, 200 amp surge current (30 seconds), and ½ second surge for higher loads.
Keheng lithium batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer ultra-fast charging and discharging, high efficiency, and longer cycle life – plus no maintenance!
Approximately 75-80% of the battery capacity will remain after 3000 cycles in applications recharging at 0.5c or lower. We have seen life spans well over 5000 cycles in our lab testing.
