48V (51.2V) LiFePO4 Forklift Battery Series — 200 / 300 / 400 / 500Ah (400Ah Reference Model)

LJY-48V400-FLT 48V (51.2V) 400Ah LiFePO4 forklift battery, front view, white background — Appearance, color and logo customizable per customer request.

Product Overview

A 48V-class 400Ah LiFePO4 traction battery for electric counterbalance forklifts (typically 1.5–2.5t class), reach trucks and heavy pallet stackers — the largest installed base of electric warehouse trucks. Forklift dealers, rental fleets and battery service companies replace lead-acid trays truck model by truck model, which makes 48V 400Ah a high-repeat lithium SKU.

Fit is decided by the tray dimensions, the minimum battery weight (counterweight) and the charger/controller interface — all configured per project. For 80V trucks see the 80V 400Ah forklift battery; for an overview see the 48V–80V forklift guide.

Appearance, color and logo customizable per customer request.

Specifications

How to read Status — three classes: [Industry reference] = standard reference parameter common to this product class (not an LJY test result). [Optional configuration] = configurable per OEM/ODM project (BMS communication, parallel/series setup, heating, enclosure, logo). [Confirmed per project] = fixed only in the datasheet issued with your quotation. Arithmetic: energy = nominal voltage × Ah.

Group	Parameter	Value	Status
Electrical	Voltage class	48V class: 15S = 48.0V or 16S = 51.2V nominal	[Industry reference]
Electrical	Capacity / energy	15S: 48.0V × 400Ah = 19.2kWh · 16S: 51.2V × 400Ah = 20.48kWh (about 19.2–20.5kWh)	[Industry reference] — arithmetic
Electrical	Continuous / peak discharge	Sized to truck controller (lifting + travel peaks, regen)	[Confirmed per project]
Electrical	Charge profile / charger	LiFePO4 CC/CV; charger communication per project	[Confirmed per project]
BMS	Protections	Over-charge/discharge, over-current, short-circuit, temperature, balancing	[Industry reference]
BMS	Truck / charger communication	CAN to truck controller and charger — protocol per project	[Optional configuration]
BMS	Telematics / SOC display	4G/cloud monitoring; SOC display	[Optional configuration]
Thermal	Self-heating (cold store)	Available on request	[Optional configuration]
Mechanical	Tray dimensions	Matched to the truck compartment (DIN/BCI tray reference)	[Confirmed per project]
Mechanical	Counterweight / total weight	Ballast to meet truck minimum battery weight	[Optional configuration] · value [Confirmed per project]
Mechanical	Connectors	REMA / Anderson-type	[Optional configuration]
Mechanical	IP rating	Per enclosure design	[Confirmed per project]
Cells	Cell brand / traceability documents	Stated per order; documents on request	[Confirmed per project]
Commercial	Certificates / MOQ / lead time / warranty	Per model and order	[Confirmed per project]

Optional configurations (OEM/ODM)

LJY Energy supplies this model as an OEM/ODM configurable build. The items below are configured per customer project — they are not fixed catalog defaults.

Series count: 15S (48.0V) or 16S (51.2V) to match the truck controller and charger.
Counterweight: steel ballast to meet minimum battery weight.
CAN integration with truck and charger — confirmed per project.
Telematics and SOC display options.
Self-heating — available on request, to be confirmed per project.
Branding: Appearance, color and logo customizable per customer request.

BMS, communication & protection

Warehouse trucks combine lifting peaks, travel and regenerative braking; the BMS must cover controller peak and regen charge current.

BMS sizing guide

Load / use case	Suggested BMS rating
Single-shift counterbalance / reach truck	BMS sized to controller continuous and peak
Multi-shift with opportunity charging	Charger current and CAN per project
Cold store	Self-heating option

Send truck brand/model, controller, existing tray size and minimum weight, charger model and shifts per day.

Size, handling & fitment

Measure the compartment (L×W×H) and read the minimum battery weight from the data plate; ballast is often needed because lithium is lighter than lead-acid.

Final dimensions, weight and connector positions are fixed in the project drawing.

Series options: 200 / 300 / 400 / 500Ah (48V class)

This page covers the whole 48V forklift line as an OEM/ODM series. 400Ah is the reference model; the other capacities share the same architecture and are built to the tray and truck. Energy = nominal voltage × Ah.

Capacity	15S energy (48.0V × Ah)	16S energy (51.2V × Ah)	Typical use class (industry reference)
200Ah	9.6kWh	10.24kWh	Pallet stackers, light-duty trucks
300Ah	14.4kWh	15.36kWh	Reach trucks, light counterbalance
400Ah	19.2kWh	20.48kWh	Counterbalance (about 2–3.5t class) — reference model on this page
500Ah	24kWh	25.6kWh	Heavy-duty or multi-shift counterbalance
