JK Smart ESS BMS 8-16S 100A (1A Active Balancer)
The JK Smart ESS BMS 8-16S 100A is a smart energy-storage BMS for lithium battery banks built from 8 to 16 cells in series. It offers 1A active balancing, a 100A current class, Bluetooth, CAN and RS485 communication and a colour LCD, and it supports LiFePO4, NMC and LTO packs. Yati Infotech Solution Pvt. Ltd. supplies it from Noida to pack builders, solar installers and service workshops across India.
Product Overview
Home and business storage batteries need more from a BMS than a basic cutoff. They need clear data, balanced cells and a way to talk to the inverter. The JK ESS BMS is made for this kind of stationary, smart-energy work.
This board watches each group of cells in series and controls the main battery current path. It also exchanges operating information with the energy system. You set the active cell count and chemistry to match your finished pack, so the same board can serve small 24V banks and full 48V systems. Protection covers cell over-voltage, cell under-voltage, discharge over-current, short circuit and temperature faults.
You will see this product searched under many names, including JK ESS, JK Smart ESS, JKESS, JK ESS 8S 16S 100 Amp and 8S 16S JK ESS. They all point to the same board.
Who This BMS Is For
- Home solar owners who want a managed 48V battery with inverter communication
- Pack builders who assemble configurable 8S to 16S storage modules
- Installers who need quick commissioning through an app and an on-board display
- Workshops that build and service inverter and backup batteries
Key Features
- 8S to 16S range for 24V to 48V class systems

- 1A active balancing that moves energy between cell groups
- LiFePO4, NMC and LTO support
- RS485, parallel RS485 and CAN communication

What Does 100A Mean?
The 100A rating describes the current the board can carry, not the size of your battery. Amp-hour capacity is a separate matter, because it depends on your cells. A 100Ah pack and a 280Ah pack can both use a 100A BMS, as long as the load stays inside the current rating.
To see what that means for power, multiply voltage by current:
- A 24V pack at 100A delivers about 2.4kW.
- A 48V pack at 100A delivers about 4.8kW.
- A 51.2V pack at 100A delivers about 5.1kW.
If your inverter or loads need more than that, choose a higher-current board, and allow for surge current when large loads start.
What Does 1A Active Balancing Do?
Cells drift apart with use. Some hold more charge, some less, and the voltage gap between groups widens. A passive balancer burns off the excess as heat. An active balancer, like this one, moves charge from stronger groups to weaker ones.
The “1A” in the name is the balancing current, which is how much energy the board can move at one time. Active balancing manages normal divergence. It cannot restore lost capacity or fix a loose busbar, and a weak cell group can still reach a protection limit early. Good cell grading and solid connections remain essential.
Inverter Communication, App and Display
Communication is what makes an ESS BMS different from a basic one. This board offers RS485, parallel RS485 and CAN interfaces, so it can share battery information with a compatible inverter. The parallel RS485 interface supports addressed communication in expandable battery banks.
Choosing a protocol is a separate step from wiring. Your inverter must support the protocol, and the pinout, cable and settings must match. Check your inverter’s documentation before you buy.
The Bluetooth app and the colour LCD give two ways to see what the battery is doing. You can read cell voltages, total voltage, current direction, temperatures and alarms, which makes commissioning and fault-finding much faster.
100A or 150A: Which Should You Choose?
Pick the board that covers your continuous current with some headroom. A 100A board suits batteries that feed moderate loads, such as typical home inverters. A 150A board suits heavier loads and extra headroom. Balancing current also differs between models, so ask Yati to compare them for your setup.
Whichever you choose, the whole current path matters. Size the cables, busbars, terminals and fuse or breaker for the full current, and keep the board in a spot with good airflow.
Where You Can Use It
- Residential solar storage batteries
- Home ESS cabinets built from 8S to 16S modules
- 100A-class inverter and backup batteries
- Off-grid and hybrid solar systems
- Expandable parallel battery banks
- Battery assembly and service workshops
Commissioning Checklist
- Read the manual for your exact hardware revision before you start.
- Set the chemistry and active series count to match your cell stack.
- With chargers and loads disconnected, check each cell group’s voltage and connect the sampling harness in the correct order.
- Mount the display and interface board without stressing the connectors.
- Keep communication wiring away from high-current cables.
- Start with a low current, and check the LCD and app for voltage, current direction, temperatures and alarms.
- Confirm inverter communication before you raise the load.
- Check terminal temperature and voltage drop at full current.
- Set a realistic pack capacity, so state of charge reads accurately.
- Record your settings, including chemistry, series count, balance settings and inverter protocol.
