The battery pack are made with high-quality LTO cells.

Specially designed BMS (Battery Management System) for ESS application, with over-charging, over-discharge, over-current, short
circuit or overheating protection, and RS485, RS232, Canbus communication.


KOK LTO ESS series adopt the world’s most advanced lithium battery technology - LTO battery:
With its stable 3D crystal structure, LTO (Lithium Titanate, LiTi5O12 ) chemistry is “zero-strain”, as it hardly forms unstable
SEI film during charging and discharging as opposed to the traditional graphite anode material, therefore,LTO batteries boast 3 extraordinary advantages as below:
(1) 30-Year Super Long Service Life:The LTO batteries have super long cycle life of 25,000 to 30,000 times, 100% DOD, equivalent to 30 years of service life.
(2) Amazing Low/High Temperature Performance at -50℃ ~60℃: The LTO batteries can be charged and discharged from extremely low temperature- 50℃ to ultra-high temperature 60℃, suitable for energy storage in extremely cold/hot countries and areas where other battery chemistry doesn’t work.
(3) Fast Charge/Discharge Ability:LTO is the fastest charge/discharge lithium battery at 10C continuously, which can be fully charged/discharged in 6 minutes, to support critical loads such as air condition, water pumps, EV charging, etc. in residential, commercial, industrial ESS applications.
Besides, KOK LTO ESS series are:
Wall-mounted modular design, allowing for 16 batteries in parallel max.
Wide Compatibility: KOK ESS batteries have commissioned for communication and compatibility with the major inverter and solar
charger brands such as Victron, Huawei, Goodwe, Growatt, Voltronic, Kehua, Kstar, East, Luxpower, Megarevo, INVT, Ginlong,
Sacolar, Sofar, etc. And the list is to be continued as our engineers are working on testing and commissioning with more inverter and charger brand.
20-Year max. Super Long Warranty: KOK offer 20 year max. Super long warranty period for LTO ESS battery series.

Company Introduction

KOK POWER LIMITED (KOK), founded in 2011, is pioneer of smart lithium-ion battery systems in China. Our smart batteries can display & monitor the batteries status and thus enable the devices to conserve and use power intelligently with a patented built-in battery management system (BMS) via blue-tooth or other communications through APP or on screen.

KOK is strong in R&D and manufacturing of smart battery systems, widely used in fields such as E-mobility (e-bike, e-scooter, e-skateboard, e-motorcycle, e-tricycle/rickshaw, e-wheelchair, e-golf cart, e-forklift, e-tourist vehicle, RV/caravan,marine,etc.), Energy Storage Systems (solar/wind system, telecom/base station, uninterruptible power supply/UPS/backup system) and engine starter batteries. KOK batteries can readily replace the outdated, bulky and pollutant Lead-Acid / AGM/ GEL/SLA batteries with the latest smart lithium battery technology.
