Description
The BSL Battery 51.2V Powerline 100Ah 5.1kWh Wall 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 BSL Battery 51.2V Powerline 100Ah 5.1kWh Wall Mount with fast courier delivery across South Africa.

Good battery so far
The BSL lithium battery works well for backup power. It charges properly and has been useful during load shedding. Happy with the quality. Delivery could always be faster, but the product itself is good.

Average but useful
Good battery for a home solar setup. It keeps the basics running when Eskom goes off and feels like a solid buy. Not bad, just not amazing.
