About this model
This charger's listing describes it as a fast-charging smart charger for 12V (12.8V) LiFePO4 battery packs, for RVs, marine use, trolling motors, off-grid systems and related applications. Its description covers four qualities. Output: 14.6V, 40A and 584W, fully charging a 12V 100Ah battery in approximately 2.5 hours by the description, or approximately 3 hours by the listing's charging-time reference table — a difference this page notes rather than resolves, since both figures come from the same listing. Charging intelligence: three-stage intelligent charging with 0V and deep-sleep BMS activation for batteries requiring recovery from low-voltage or sleep mode. Safety: five-layer safety protection covering over-temperature, short-circuit, over-voltage, over-current and reverse-polarity protection. Construction: a durable aluminium alloy housing with a cooling fan and a portable handle, designed for indoor and dry environments and not waterproof.
The table's most useful rows for a buyer are the charging curve, the efficiency and the environment rating together. The charging curve runs pre-charge, then constant current, then constant voltage, under MCU control, at 90% efficiency or higher; the AC input is 100–240V at 50/60Hz, so the charger suits mains supplies in most markets without a voltage converter; and the protection class is indoor use only, with fan-assisted active cooling and an operating temperature range of -20°C to +40°C. The output connector is a 50A Anderson connector plus an M8 ring terminal, which must match the pack's input — a charger with the wrong connector is a mismatch even when its voltage and current are right.
The listing states the charger is CE, FCC and RoHS certified with a 2-year warranty, and that OEM and ODM customisation is available for bulk orders, including custom voltage and current specifications, connectors, housing colour and private labelling. It also states that additional country-specific certification support is available on request for qualifying order volumes. Those are this listing's statements, and a buyer who needs a specific certification for a target market should ask for the documents for that market rather than assuming the standard certifications cover it. The charging-time reference table, as listed, gives approximately 3 hours for 12V 100Ah, 5.5 hours for 12V 200Ah, 8 hours for 12V 300Ah and 10.5 hours for 12V 400Ah, while the description's prose gives 2.5 hours for 100Ah and 5 hours for 200Ah; a buyer planning charge schedules should confirm which figure applies to the order's conditions.

How to read this table
Read the table as a specification for this listing alone. The rated capacity and nominal voltage describe the pack's energy class; the maximum charge voltage and discharge cut-off voltage describe the charger's and the device's voltage limits; the charging current and maximum continuous discharge current describe how fast the pack fills and how hard it can work; the cycle life describes the listing's stated durability; and the dimensions and weight describe the physical pack. No row in this table describes any other model, even one with a similar voltage or capacity.
Two rows deserve a direct question before ordering. The certificate row states what this listing claims, and the certificate set for the exact model should be confirmed in documents, since certificates are available upon request. The delivery and warranty rows state this listing's terms, and they should be confirmed for the exact order quantity, because terms stated for one listing do not transfer to another. A buyer who confirms those two rows in writing has removed the two most common sources of dispute in battery orders.
Confirm before you order
Send the device facts with your inquiry: device type, space, voltage, capacity, peak current, and this model description. Ask for the certificate set for this exact model, confirm the minimum order, price basis and lead time for this listing, and confirm payment and warranty terms before you pay. If the device's space, voltage or peak current differs from this listing, say so in the first line — the custom route, not a forced fit, is the honest next step.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the chemistry. If a page on this site matches, quote its model description and listing details. If nothing matches, say so and describe the chemistry and voltage you need, so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the price basis and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom design, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model description if you have one, and the documents you need. That is the whole inquiry — no separate form, no account, no extra step.
What to send us now
Send one message with your device type, the space the pack must fit, the voltage and capacity you need, the peak current if it matters, and the model description if a page on this site already matches. Add the documents you need — certificates are available upon request — and whether you need a listed model or a custom design. Use the contact page or write to [email protected], or call +86-755-25629920. A specific message like that is what turns a range of hundreds of models into a short, answerable question.
