About 2.5-5.4kWh Batteries

2.5-5.4kWh batteries

Small-format batteries cover the jobs that do not need a whole-home bank: a cabin, a shed, a telecom cabinet, a single critical circuit. This collection carries 139 SKUs in the 2.5-5.4 kWh range.

What to check

  • Usable kWh, not nameplate. Plan on 80-90% depth of discharge for LFP; an AGM unit in the same class gives roughly half that usable.
  • Output vs capacity. A 5kWh battery with a 2kW inverter cannot run a well pump; check continuous and surge output.
  • Voltage and chemistry. 12V, 24V and 48V modules are not interchangeable - match the inverter/charger and its lithium profile.
  • Expansion. Confirm series/parallel limits and whether the BMS supports the intended bank size.

Ordering

Send the load, runtime and inverter model to the quote desk and we will confirm the battery count and BMS compatibility.
