Overview
The Felicity FLA48100 is a 5.12kWh, 48V (51.2V nominal, 100Ah) lithium iron phosphate (LiFePO4) battery for home and small-business solar and inverter systems. It is Felicity's lower-priced 48V 5kWh model, with a built-in smart battery management system (BMS), breaker and fuse, an LCD + LED display, built-in Wi-Fi monitoring and a rating of 6,000+ cycles. Who it's for Homes, shops and small offices running a 48V inverter of about 3kVA to 5kVA, charged from solar panels, the grid or both. You can start with one battery and add more later: up to 15 can be connected in parallel (76.8kWh in total). What it can power At least 95% of the 5.12kWh is usable, roughly 4.86kWh. As a rough guide, that runs a 500W load (lights, 2-3 fans, a TV, a laptop and Wi-Fi) for about 9 hours, or a 1,000W load (adding a fridge or freezer) for about 4 to 5 hours. The recommended continuous output is about 5,000W (100A), with short peaks of 7,500W (150A) for 15 seconds. Running air conditioners, pressing irons, kettles or water heaters will drain it quickly. These figures are estimates; actual runtime depends on your appliances and your inverter's efficiency. Key specifications in plain language • Long life: rated for 6,000+ cycles (at 25°C, 0.5C, 90% depth of discharge), which is many years of daily use. • Safe chemistry: LiFePO4 is the most stable lithium chemistry for home storage, and the built-in smart BMS, breaker and fuse protect against over-charge, over-discharge, over-current and short circuits. It is certified to UN38.3, CE-EMC and IEC 62619. • Smart: an LCD + LED display shows the state of charge, built-in Wi-Fi lets you monitor the battery remotely, and RS485/CAN communication lets compatible inverters read the battery directly. • Flexible installation: 663 x 400 x 178mm and 48kg, wall-mounted or floor-mounted, indoors only (IP21). Compatibility Use it with a 48V inverter or hybrid inverter that supports lithium batteries, and set the inverter to the lithium (LiFePO4) battery type before first use. Felicity states it is compatible with leading inverter brands; use the right communication cable for your inverter (CAN or RS485). Connect batteries in parallel only, never in series. Install it indoors, away from water and heat. Installation should be done by a qualified installer. Cables, the mounting bracket and accessories should be confirmed when you order. Warranty & support Up to 7 years from Felicity Solar, the manufacturer. We supply this product through a partner supplier, so claims are handled by Felicity through that supplier; keep your proof of purchase and installation records.

Questions about this product
Which inverters is it for?
48V inverters and hybrid inverters of about 3kVA to 5kVA that support lithium batteries. Felicity lists compatibility with leading inverter brands; set the inverter to the lithium (LiFePO4) battery type and use the right communication cable (CAN or RS485).
How is it different from the Felicity LPBF48100?
Both are 48V (51.2V) 5kWh LiFePO4 batteries from Felicity. The FLA48100 costs less and, per Felicity's datasheet, has a longer warranty (up to 7 years vs 5), a higher recommended output (5,000W vs about 2,500W), built-in Wi-Fi monitoring and room for up to 15 batteries in parallel. It is heavier (48kg) and taller (663mm).
How many can I connect together?
Up to 15 in parallel (76.8kWh in total). Connect them in parallel only, never in series.
How long will it run my appliances?
About 4.86kWh is usable: roughly 9 hours for a 500W load or 4 to 5 hours for 1,000W. These are estimates; actual runtime depends on your appliances and your inverter's efficiency.
Where can I install it?
Wall-mounted or floor-mounted, indoors only (IP21). It weighs 48kg and measures 663 x 400 x 178mm, so a solid wall and two people are needed for wall mounting.
What warranty does it have?
Up to 7 years from Felicity. Claims go through Felicity via our supplier, so keep your proof of purchase and installation records.

Overall
We found no independent owner reviews of this exact model (FLA48100), so this summary reflects Felicity lithium batteries in general. Felicity is one of the most widely sold lithium battery brands in Nigeria, and buyers value its local availability, compatibility with popular inverters and long warranty. Opinions online are mixed: the most common complaints are about the battery not communicating with the inverter and about slow support.
Review 1
An installer who has fitted Felicity batteries said they work well and the customer support is good, but advised buyers to respect the battery's charge and discharge current limit and not pair it with an oversized inverter.
Review 2
A South African retailer's buying guide explains that most modern hybrid inverters such as Sunsynk and Deye talk to the battery over CAN, that RS485 is older but widely supported, and that buying the correct communication cable is crucial.
Review 3
Another buyer of a different Felicity battery said it began tripping its circuit breaker after a few months and that their refund request was refused, a reminder to buy from a seller that will handle warranty claims and to keep proof of purchase and installation.
