Saltra LFP / Charger Guide

The charger must match the battery, not just the plug.

LiFePO4 charging depends on the correct voltage, current, connector, charge profile, and safety behavior. A wrong charger can create nuisance trips or damage risk.

Buyer pain point

Voltage confusion is common.

12V LiFePO4 packs are usually charged around 14.6V. 51.2V LiFePO4 packs are usually charged around 58.4V.

Guide

14.6V chargers

Used for 4S / 12.8V nominal LiFePO4 packs. Current rating should match the battery capacity, BMS, wiring, and use case.

Guide

58.4V chargers

Used for 16S / 51.2V nominal LiFePO4 packs. These are common in storage, inverter, and backup systems.

Guide

Current rating

Higher current charges faster, but it also increases heat and stress on connectors, wiring, and the BMS.

Guide

Connector choice

The connector must match the pack design. Saltra reviews connector style, cable size, polarity, and customer use case.

Common charger path.

ItemWhy it matters
12V / 4S LiFePO4Typically uses a 14.6V LiFePO4 charger.
51.2V / 16S LiFePO4Typically uses a 58.4V LiFePO4 charger.
Fast chargingRequires checking BMS, wiring, connector, heat, and cell limits.

Next step

Do not guess the build.

Tell Saltra what you are building, your target voltage, application, capacity goal, and whether you already have an inverter, charger, or BMS. We will use that information to recommend a cleaner battery build path before you buy.
