Description
The 5.1kwh BSL Lithium Battery Rack Mount is engineered for South African load-shedding conditions where batteries cycle daily, often multiple times, and where the combination of high ambient temperatures and frequent charge-discharge cycling tests battery chemistry to its limits.
LiFePO4 (Lithium Iron Phosphate) chemistry was chosen for this application for good reason: it is the safest lithium chemistry available (no thermal runaway risk), it maintains a flat discharge curve (stable voltage throughout discharge rather than the steep drop of lead-acid), and it delivers 3 000–6 000+ cycles at 80% depth of discharge versus 300–500 cycles for an equivalent lead-acid battery.
The built-in Battery Management System (BMS) monitors every cell in the pack for over-voltage, under-voltage, over-current, over-temperature, and under-temperature conditions, disconnecting the battery before any condition can damage the cells. CAN bus and RS485 communication ports allow the battery to communicate its state of charge, state of health, cell temperatures, and cycle count directly to compatible hybrid inverters including Deye, Sunsynk, Victron, GoodWe, Fronius, SMA, and LuxPower.
Multiple units can be connected in parallel to scale the storage capacity to match your household’s consumption during loadshedding. Correct installation by a qualified electrician with a valid COC (Certificate of Compliance) is recommended and may be required for warranty validity.
End Loadshedding provides the 5.1kwh BSL Lithium Battery Rack Mount with fast courier delivery across South Africa.

Works well for backup
Good value for solar backup. It is not over complicated and works well with the system. Good buy, nothing serious to complain about.

Good backup for load shedding
Good battery for a home solar setup. It keeps the basics running when Eskom goes off and feels like a solid buy.

Battery works very well
The battery does what I needed. Good for load shedding, simple to use and no issues so far.
Sipho Dlamini (verified owner) –
Happy overall
The battery does what I needed. Good for load shedding, simple to use and no issues so far. Only giving four stars because I still want to see how it performs long term.

Happy overall
Solid lithium battery. It gives peace of mind when the power goes out and the quality feels proper. Delivery could always be faster, but the product itself is good.
