LiFePO4 Battery Capacity Guide: From 6Ah to 400Ah
Capacity is the second choice after voltage, and this guide lays out the capacity ladder exactly as the listed models define it. The 12V family runs from 6Ah through 12Ah, 15Ah, 30Ah and 42Ah to 280Ah and 300Ah, each with a full table. The 48V family runs from 100Ah models with full tables through a 170Ah overview to 200Ah, 314Ah and 400Ah units as listed names. The home storage range adds 24V from 100Ah to 230Ah and a catalogue span from 50Ah to 400Ah as range descriptions.

This guide explains the ladder and links to the model pages. It does not assign a capacity to a model that does not list it: a capacity figure on a model page comes from that model's table or listed name, and nowhere else.

Reading the ladder
Small capacities (6Ah to 15Ah) fit small backup, device and lighting jobs, where the binding figures are current ratings as much as capacity: 3A to 21A charging across those models. Mid capacities (30Ah to 42Ah) fit general 12V use and small off-grid jobs. Large capacities (280Ah to 400Ah) fit golf-cart, RV, home backup and whole-home solar jobs, where dimensions, weight and terminal type join capacity as binding figures.
Intermediate capacities — 50Ah, 80Ah, 100Ah, 120Ah, 150Ah, 200Ah — are addressed here as ladder rungs, not as models. A 100Ah question, for example, points to the two 48V 100Ah models with full tables, and a 200Ah question points to the 200Ah units as listed and to the 48V range description.
Where no model lists a rung exactly, this guide says so rather than inventing a model for it.
Energy figures follow capacity only where a model lists them: 76.8Wh at 6Ah, 153.6Wh at 12Ah, 192Wh at 15Ah, 384Wh at 30Ah, 537.6Wh at 42Ah, 5120Wh at 48V 100Ah, and 3840Wh as listed for both the 280Ah and the 300Ah 12V models. The twin 3840Wh figures are recorded exactly as listed and are not reconciled. Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Before ordering
Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Confirm the specification for the model actually ordered, not for a neighbouring model or a series range.
