12.8V LiFePO4 Private-Label Program for RV & Marine Battery Brands (100–300Ah)
Product Overview
This page is for small and mid-sized battery brands — RV, caravan, camper-van and marine labels, wholesalers with their own brand, and pack assemblers — who want to launch or extend a 12.8V (12V class) LiFePO4 line under their own name. It focuses on the 100–300Ah range, where most RV house-bank and marine house/trolling demand sits, and on how a private-label SKU is specified and approved.
LJY Energy is a China-based LiFePO4 battery supplier and OEM/ODM solutions provider offering customization, project-confirmed specifications and export supply coordination. Every option below is configured per customer project; nothing on this page is a verified standard product unless stated in your project datasheet.
Appearance, color and logo customizable per customer request.

BMS, communication & protection
RV and marine loads differ: inverters, windlasses and trolling motors create short high peaks. Size the BMS to the real load, not only the Ah rating.
BMS sizing guide
| Load / use case | Suggested BMS rating |
|---|---|
| RV house bank with 1–2kW inverter | BMS ≥ inverter continuous current + margin |
| Marine trolling motor | BMS sized to motor max current |
| Windlass / thruster on the same bank | Confirm peak and duration with your design |
Bluetooth and CAN are optional configurations. Send the inverter, charger, DC-DC and alternator setup with your RFQ.
Size, handling & fitment
Buyers in the UK, Germany and Canada often choose the case format first and the capacity second. The matrix lists the common formats with their published reference envelopes. Every row is a project option: no LJY dimensions, stock or measured fit are stated, and the capacity that fits a given envelope is confirmed per project.
| Group | Parameter | Value | Status |
|---|---|---|---|
| DIN (EN) | LN3 / H6 case envelope | 278 × 175 × 190 mm (length × width × height). Reference: EN 50342-2 / IEC 60095-2 size table; the envelope of a lead-acid starter battery that a lithium pack is built to fit | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] (capacity and dimensions) |
| DIN (EN) | LN4 / H7 | 315 × 175 × 190 mm | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] |
| DIN (EN) | LN5 / H8 | 353 × 175 × 190 mm. Public competitor listings show this case at 172Ah (Fogstar Drift H8 DIN fit) and 180Ah (Powerkönig PK12180DIN); these are competitor figures, not LJY data | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] |
| DIN (EN) | LN6 / H9 | 394 × 175 × 190 mm | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] |
| BCI Group | Group 24 | Maximum overall 260 × 173 × 225 mm (10¼ × 6 13/16 × 8 7/8 in). Reference: Battery Council International group-size chart | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] |
| BCI Group | Group 27 | Maximum overall 306 × 173 × 225 mm (12 1/16 × 6 13/16 × 8 7/8 in) | [Industry reference] (envelope) · [Optional configuration] · [Confirmed per project] |

| Custom case | Own mould or marked-up drawing | Any other envelope, colour and label layout, for brands that want a case of their own | [Optional configuration] · [Confirmed per project] |
| What LJY fixes per project | Capacity that fits an envelope, final dimensions, weight, terminal type and position, hold-down method | Set against your drawing and the cell format; the quotation lists them. The envelopes above are references for matching a replacement size, not LJY product dimensions, and a case size does not by itself decide the Ah | [Confirmed per project] |
Sources for the reference envelopes: Battery Council International group-size chart; EN 50342-2 and IEC 60095-2 (LN size series). Competitor examples: Fogstar Drift and Powerkönig, public pages checked 15 October 2026.
Heated and low-temperature options are set the same way. LiFePO4 cells should not be charged below about 0 °C unless they are warmed, so the BMS can block charging below a set temperature and an optional self-heating function can warm the cells first. The cut-off temperature, heater trigger, heater power source (the battery itself or an external source) and the resulting charge time in the cold are confirmed per project and are not stated as fixed values here.
Documents for a UK, EU or Canada brand launch are agreed in the quotation: transport test summary and safety data sheet, the conformity documentation scope for your market (CE or UKCA, and the obligations of the brand owner or importer under Regulation (EU) 2023/1542, see the EU Battery Regulation guide), and, if a German vehicle-builder or dealer asks for an EMC report such as ECE R10, whether a report exists for the exact model. A document is listed only if it exists; none is implied by this page.
For marine use, confirm compartment ventilation, vibration and terminal protection requirements in the project specification.

EU brand owners: who is the “manufacturer”, and when do label, QR code and passport apply?
For a 12.8V (12V class) private-label RV or marine battery sold in the EU, the duties of Regulation (EU) 2023/1542 sit with the EU party that places the finished battery on the market, not with the supplier of components. This section sets out what the official texts say so you can brief your compliance adviser. It is not legal advice, and LJY makes no statement that it is an EU manufacturer, importer or authorised representative or that any model is compliant. The regulation itself is in the EUR-Lex text; our general guide is the EU Battery Regulation buyer’s guide.
| Group | Parameter | Value | Status |
|---|---|---|---|
| Roles | Definition of “manufacturer” (Art. 3(33)) | “any natural or legal person who manufactures a battery or has a battery designed or manufactured, and markets that battery under its own name or trademark or puts it into service for its own purposes”. A brand owner that markets a private-label battery under its own name falls within this wording; confirm with your adviser. | [Official text, EUR-Lex] |
| Roles | Finished private-label packs | The economic operator placing the finished battery on the EU market is responsible for the passport and the data in it. A non-EU supplier can be authorised in writing to create or update the passport, which does not make it the EU manufacturer or importer (FAQ 2.1, 2.4). LJY supplies the data and documents agreed per project. | [Commission guidance] · [Confirmed per project] |
| Roles | Cells, modules, BMS or enclosures for EU assembly | Imported cells or modules that are only components are not the finished battery; “the EU entity that completes the battery becomes the manufacturer” (FAQ 3.4). Imported packs plus a BMS assembled in the EU: the EU entity completing and placing the battery on the market is responsible (FAQ 2.5). Components for later assembly may be imported without a passport (FAQ 4.3). A limited exception applies to do-it-yourself kits. | [Commission guidance] · [Optional configuration] |
| Roles | Duty of the cell or module supplier (Art. 39) | “Suppliers of battery cells and battery modules shall provide the information and documentation necessary to comply with the requirements of this Regulation when supplying battery cells or modules to a manufacturer.” What LJY provides is listed per project in the quotation. | [Official text, EUR-Lex] · [Confirmed per project] |
| Roles | Two or more units | Packs sharing a common BMS or components that form one working battery count as one battery; complete, independently functioning units below 2 kWh are assessed individually (FAQ 3.2, 3.3). The assessment is made case by case. | [Commission guidance] |
| Group | Parameter | Value | Status |
|---|---|---|---|
| Dates | Separate-collection symbol | From 18 August 2025 all batteries carry the separate-collection symbol (Art. 13(4)). | [Official text, EUR-Lex] |
| Dates | General-information label (Annex VI Part A) | Art. 13(1): from “18 August 2026 or 18 months after the date of entry into force of the implementing act referred to in paragraph 10, whichever is the latest”. The labelling implementing act was due by 18 August 2025. We found a draft notified to the WTO on 22 December 2025 (G/TBT/N/EU/1181) and no adopted act, so the label date is not yet fixed. Check before you print labels. | [Official text] · [Partly verified: act status] |
| Dates | QR code on every battery | From 18 February 2027 all batteries carry a QR code (Art. 13(6)). For industrial batteries with a capacity greater than 2 kWh it gives access to the battery passport. | [Official text, EUR-Lex] |
| Dates | Battery passport | From 18 February 2027 each industrial battery “with a capacity greater than 2 kWh” placed on the market or put into service needs a passport (Art. 77(1)). The economic operator placing the battery on the market attributes the unique identifier (Art. 77(3)). | [Official text, EUR-Lex] |
| Dates | Passport content in 2027 | Carbon-footprint, recycled-content and due-diligence data are not required in passports created from February 2027 (FAQ 7.2); due-diligence reports are required from August 2027 (FAQ 7.3). | [Commission guidance] |
| Classification | Industrial vs portable (Art. 3(13), 3(9)) | “Industrial battery” includes “any other battery that weighs more than 5 kg” that is not an EV, LMT or SLI battery; a portable battery is sealed and weighs 5 kg or less and is not designed specifically for industrial use. Pack weight is confirmed per project and decides the category. | [Official text, EUR-Lex] · [Confirmed per project] |
The 2 kWh line for a 12.8V pack falls at 156.25Ah (12.8V x 156.25Ah = 2,000Wh). Art. 77 says “greater than 2 kWh”, so exactly 2,000Wh is not above it; 157Ah is the first whole-Ah size above. These rows are arithmetic, not product claims: capacity options are confirmed per project. For scale, the 12.8V 314Ah format on the 12.8V 314Ah model page (12.8V x 314Ah = 4,019Wh) is well above the 2 kWh line.
| Group | Parameter | Value | Status |
|---|---|---|---|
| Energy | 12.8V (12V class) x 100Ah | 1,280Wh — below 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 150Ah | 1,920Wh — below 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 156.25Ah | 2,000Wh — exactly 2,000Wh: not “greater than 2 kWh” | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 157Ah | 2,009.6Wh — above 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 172Ah | 2,201.6Wh — above 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 200Ah | 2,560Wh — above 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 230Ah | 2,944Wh — above 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
| Energy | 12.8V (12V class) x 300Ah | 3,840Wh — above 2 kWh | [Industry reference] — arithmetic (Wh = V x Ah) |
