Every module is a drawer. A blind-mate connector at the back engages the rack’s high-voltage bus, balance bus and comms in one push — no cables to route or terminate.

Inside the rack
Three paths, zero cables.
Behind the drawers, copper busbars link the modules in series, a shared two-wire balance bus runs past every level, and CAN comms run up the rack to the controller.

Module balancing
Burns off the extra, one module at a time.
When one module’s highest cell passes 3.450 V while another’s stays below 3.400 V, the rack closes that module’s two balance contactors. Its extra energy runs up the shared balance bus into the controller’s 1000 W resistors for a 30-second window.

Bidirectional current limiter
Racks balance each other, gently.
Add a new rack to a live bank at a different voltage — no manual voltage matching, no tools. The limiter holds the equalising current in either direction until the rack voltages match, then the racks share the load.

Seamless CAN failover
If the master drops, a slave takes over.
One rack leads the CAN link to the inverter. If it goes offline, the next rack is promoted to master instantly — the inverter never loses its battery.

THE LBSA RHINO INTELLIFLEX HV
THE HV‑104‑14WFRE IS DESIGNED FOR SPEED, STRENGTH, AND SEAMLESS SCALABILITY.
A revolutionary battery born in the heart of South Africa, the HV‑104‑14WFRE is designed for speed, strength, and seamless scalability.
Its wire-free, plug-and-play modular design makes installation quick and clean, while built-in bidirectional current limiting allows effortless expansion - add new batteries without voltage matching or tools. Each module is hot-swappable and self-balancing, and if a Master battery fails, a Slave takes over instantly to ensure zero downtime. The system supports up to 60 units in parallel, delivering an impressive 5.4 MW of stable power with intelligent failover and monitoring.
Proudly designed and built locally, it's a future-ready solution engineered for reliability, simplicity, and South African resilience.

Revolutionize Your Grid-Tied System with The Rhino Intelliflex High Voltage Battery
Have you got a grid tied inverter or DC device that takes solar panels but cant benefit in terms of the high demand tariffs due to weak sun in those times?
Step into the world of Battery-PV DC coupling.
This revolutionary system allows customers to drastically reduce their power bill with their current grid tied setup by storing excess solar energy thought out the day and then only using it during the peak times, allowing for a much better ROI.
How this system works: when your grid tied inverters are not under load the battery will absorb all the excess power from the PV and when the sun goes down the battery will turn on its discharge contactor to allow discharging directly into the grid tied invertes PV port acting as your own little sun!
HOT-SWAPPABLE MODULES
Need to replace a module mid-operation? No problem. The HV-104-14WFRE allows hot-swapping of modules, regardless of their state of charge. The system's internal balancer automatically discharges higher-voltage modules to match the rest, ensuring seamless performance and minimal disruption.
WIRE-FREE DESIGN
Forget complicated wiring diagrams and tangled installations. The HV-104-14WFRE uses a wire-free design, reducing setup time, eliminating wiring errors, and ensuring a safer, cleaner installation.
SEAMLESS CAN COMMUNICATION FAILOVER
Downtime? Not on our watch. If a Master battery in your rack fails, the system automatically promotes a Slave battery to take over communication with the inverter. This failover mechanism happens instantly, keeping your system running smoothly with zero downtime. You can scale this setup up to 62 racks in parallel, reaching a massive 5.4MW capacity—without compromising stability.
EASY MODULE SECURING
Easily secure the controller and module in place with a secure drawer lock
HOT BATTERY SWAPPING MADE EFFORTLESS
Our bidirectional current limiter allows you to add a new battery regardless of its state of charge or voltage. It intelligently balances itself by either charging or discharging at up to 10A—no specialist tools or knowledge required. Future expansion or battery replacement has never been easier.
LARGE EXPANSION
Parallel up to 60 batteries with auto master-slave assigning
POWERFUL BIDIRECTIONAL CURRENT LIMITER
Current limiting
Our smart controlled current limiter can limit the current going in to or out of the battery at 15 amps to ensure your batteries, whether adding or servicing, can resynchronize effortlessly.
Module balancing
The current limiter doubles as a module balancer allowing your newly added battery modules voltage to be synchronized into the battery seamlessly.
INDEPENDENT CHARGE AND DISCHARGE CONTROL
Battery over discharged?
No problem with our double contactor diode approach. Your battery can continue waiting for a charge while not giving any power out, protecting your valuable cells.
Contactor AUX feedback
All contactors in the LBSA HV battery feature auxiliary feedback so that we are aware of any contactor failure.
Charge termination while allowing discharge
LBSA HV allows for your battery to be able to be discharge while not allowing charge in case of a cell over voltage. This comes in handy when you need your modules or cells to balance whilst not interrupting the rest of the battery banks.
Breaker with trip and feedback function
We will know if the breaker is not closed ensuring that little bit of extra safety by promoting you to close the breaker.
We can also disengage the contactors in the event the breaker has been turned off.
In the event of contactor failure the battery can trip the breaker if need be.
