The EG4 WallMount 280Ah All Weather Battery is a 14.3kWh LFP (lithium iron phosphate) battery engineered for reliable whole home battery backup in demanding residential and light commercial environments. With integrated self-heating for cold-weather operation, EMP hardening, and dual fire arrestors, it is one of the most protection-hardened residential batteries available from a value-focused brand.
The 280Ah battery supports over 8,000 cycles at 80% depth of discharge, delivering a lifetime energy output of up to 82.6 MWh — significantly longer cycle life than NMC chemistry batteries at comparable capacity. Its 140A maximum continuous discharge rate supports heavy loads, and the 600A busbars ensure low-resistance, high-current connections for high-demand applications.
