Felicity Solar FLB48100WG1-H 5.12kWh Lithium Iron Phosphate Battery features

5.12kWh nameplate energy at a 100Ah nominal capacity, with depth of discharge rated at >95%.

Cycle life rated at >6,000, so the FLB48100WG1-H is specified for daily cycling rather than standby duty.

100A of continuous charge and discharge current on the FLB48100WG1-H, rising to a 150A peak sustained for 15 seconds.

Up to 32 units in parallel, taking a single bank to 163.84kWh without changing the module.

Four protection layers sit across the FLB48100WG1-H's 100A current path: a built-in smart BMS, a breaker, a fuse and a Thermal Runaway Management System.

48.5KG net and 53KG packed, in a 650X450X174MM enclosure that is wall-mounted or floor-mounted.

About the Felicity Solar FLB48100WG1-H 5.12kWh Lithium Iron Phosphate Battery

The Felicity Solar FLB48100WG1-H is a 5.12kWh lithium iron phosphate battery with a 100Ah nominal capacity, a depth of discharge rated at >95%, a cycle life of >6,000 and headroom to parallel 32 units for 163.84kWh. Continuous charge and discharge current is 100A, peaking at 150A for 15 seconds. Protection is layered rather than bolted on: a built-in smart BMS, a breaker, a fuse and a Thermal Runaway Management System. CAN2.0, RS485, WIFI and Bluetooth are all available for monitoring and system integration. The enclosure measures 650X450X174MM and weighs 48.5KG, 53KG in its packaging, and it is rated for wall-mounted or floor-mounted installation. The working range is -20°C to +55°C for charge and discharge, with storage at 0°C to +35°C, relative humidity from 5% to 95% and altitude below 2,000m. We are the authorised Felicity Solar distributor for this model and supply it with a 5 Years warranty.

Frequently Asked Questions

5.12kWh, drawn from a 100Ah lithium iron phosphate pack whose depth of discharge is rated at >95%, so almost the whole nameplate figure is reachable on each cycle.

>6,000 is the rated cycle life of the FLB48100WG1-H, a figure that describes daily cycling rather than standby service, and we supply the unit with a 5 Years warranty.

100A continuous in both directions, with a 150A peak held for 15 seconds. A built-in smart BMS, a breaker, a fuse and a Thermal Runaway Management System sit across that current path, and CAN2.0, RS485, WIFI and Bluetooth report what the battery is doing.

32 units in parallel, for 163.84kWh in one bank. Each unit measures 650X450X174MM, weighs 48.5KG net and 53KG packed, and can be wall-mounted or floor-mounted, with an operating range of -20°C to +55°C and altitude below 2,000m.
