LJY-START-SERIES 12V and 24V LiFePO4 starter cranking battery series, front view, white background

12V / 24V LiFePO4 Starter (Cranking) Battery Series — OEM/ODM for Vehicles, Marine & Equipment

LJY-START-SERIES 12V and 24V LiFePO4 starter cranking battery series, front view, white background
Appearance, color and logo customizable per customer request.

Product Overview

An OEM/ODM series of LiFePO4 engine-starting (cranking) batteries in 12.8V (4S) and 25.6V (8S): drop-in lithium replacements for lead-acid starter batteries in cars, light trucks, boats, generators and equipment. Starter batteries are built for short, very high-current bursts — a different purchase intent from our deep-cycle and house-bank models.

Distributors, marine and automotive aftermarket brands and equipment makers buy these as private-label SKUs in a few capacities. If you need a battery that both starts the engine and runs loads, see the dual-purpose model; for house banks see the 12V series and the RV & marine private-label program.

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 12.8V nominal (4S) or 25.6V nominal (8S, 24V class) [Industry reference]
Electrical Capacity ladder (reference) 12V: 30 / 60 / 80 / 100Ah · 24V: 60 / 105Ah [Industry reference]
Electrical Energy check 12.8V × 100Ah = 1,280Wh · 12.8V × 60Ah = 768Wh · 25.6V × 105Ah = 2,688Wh [Industry reference] — arithmetic
Electrical Cranking rating (CCA / pulse current) Public competitor listings quote about 600A (60Ah), 1,000A (100Ah) and 1,200A (80Ah) classes; rating basis and test method differ by supplier, so LJY values are not stated here [Confirmed per project]
Electrical Continuous charge / discharge Common market class ~100A charge / ~200A discharge [Industry reference] · [Confirmed per project]
Electrical Charge voltage About 14.4–14.6V class per 4S (alternator and charger profile confirmed) [Industry reference] · [Confirmed per project]
BMS Protections Over-charge/discharge, over-current, short-circuit, temperature protection, balancing [Industry reference]
BMS Cranking surge handling BMS surge current and cut-off behaviour during engine start [Confirmed per project]
BMS Communication Bluetooth monitoring; RS485/CAN where required [Optional configuration]
Thermal Low-temperature behaviour Charging typically blocked near 0°C; self-heating available on request, to be confirmed per project [Industry reference] · [Optional configuration]
Mechanical Case format Optional BCI Group-style or DIN-style formats (to be confirmed against the application and product design); no dimensions stated [Optional configuration]
Mechanical Terminals / polarity / vent Top-post, SAE, marine or stud terminals; left/right polarity; sealed case [Optional configuration]
Mechanical Dimensions / weight / IP rating Per model and format [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.

  • Capacity and case format: 12V 30–100Ah and 24V 60–105Ah reference; BCI/DIN-style formats as optional case formats.
  • Terminals and polarity: per vehicle or vessel.
  • Self-heating: available on request for cold-start use.
  • Dual-purpose configuration: start + house loads — confirmed per project.
  • Bluetooth/communication as an optional BMS configuration.
  • Branding: Appearance, color and logo customizable per customer request.

BMS, communication & protection

A starter battery must deliver a large current for a second or two without tripping the BMS, then accept alternator charging. The BMS surge rating, charge-voltage limits and low-temperature behaviour are the decisive project items.

BMS sizing guide

Load / use case Suggested BMS rating
Gasoline car / small engine Surge rating matched to engine size; confirm CCA basis
Diesel, truck, marine engine Higher surge and 24V option; confirm alternator voltage
Cold-start use Self-heating or low-temperature charge protection

Send engine type and displacement, existing battery group size and CCA, alternator or charger voltage, and climate. No CCA value is claimed on this page.

Size, handling & fitment

Lithium starter batteries should be fitted with a charging system whose voltage and regulation are compatible; a lead-acid charging profile (high-voltage equalisation, desulfation) should be disabled or confirmed per project.

Case format, hold-down and terminal position must match the vehicle tray; confirmed against the application and product design.

Applications

  • Cars, light trucks and vans (aftermarket)
  • Boats and marine engines
  • Generators, pumps and agricultural equipment
  • Private-label starter battery ranges for distributors

Application limits

  • Not a deep-cycle house bank unless configured as dual-purpose.
  • CCA ratings are never assumed from competitor listings.
  • Cold-start performance below 0°C is confirmed per project.

Frequently Asked Questions

What is the difference from a deep-cycle battery?

A starter battery is optimised for very high current for a short time; a deep-cycle battery for sustained discharge. Dual-purpose models combine both and are configured per project.

What CCA do your batteries have?

CCA is confirmed per project and test method; we do not copy competitor ratings.

Can a lithium starter battery replace lead-acid directly?

Often, once case format, terminals and charging voltage are confirmed. Disable lead-acid equalisation or desulfation modes.

How is MOQ set?

MOQ is confirmed per project stage (sample, pilot, production).

Which certificates apply?

Scope is confirmed per model, order and target market; none are claimed on this page.

Values marked [To confirm] or [Competitor public] are not LJY-verified defaults. Product images are product renders for illustration. Content as of October 2026.
