BMS, Communication & Protection
Every pack uses a built-in battery management system with over-charge, over-discharge, over-current, short-circuit and temperature protection plus cell balancing. The BMS current rating sets what the battery can actually deliver, so it should be chosen from the load — not from the capacity. The guide below is general engineering guidance; the BMS rating offered for your order is confirmed in the quotation.
BMS sizing guide
| Load / use case | Suggested BMS rating |
|---|---|
| House loads, fridge, lighting, inverter up to ~1,500W | 150A BMS |
| Inverter up to ~2,500W | 250A BMS |
| Inverter ~3,000W | 300A BMS + Class T fuse and heavy cabling |
| Above ~3,000W | Move to 24V/48V system |
At this size the BMS, fuse and cable — not the cells — limit output. Pair high-current builds with a properly rated Class T fuse close to the battery. Charging sources: use a LiFePO4 charge profile (14.2–14.6V absorption, equalization off); a DC-DC charger for alternator charging. See the charging voltage chart.
Size & Fitment
This capacity is usually housed in an 8D-class or larger enclosure. When replacing an 8D lead-acid or a bank of smaller batteries, check tray size, hold-down, lid clearance and terminal spacing against the quotation drawing. Final dimensions, weight and terminal layout are confirmed per project in the datasheet issued with your quotation.
A battery of this size is heavy — plan for two-person handling or a lift; handle design is an OEM option.
Applications
- Large RV and motorhome house banks
- Yachts and marine house banks
- Off-grid cabins and solar systems staying at 12V
- Expedition and overland vehicles
- Mobile medical, broadcast and workshop vehicles
Application limits
- Not an engine starting battery.
- Heavy: confirm mounting strength and handling.
- Standard version should not be charged below 0°C without low-temperature protection or heating.

How we help new battery brands configure this model
- 1. Define the use case: application, largest load / inverter or controller, charging sources and climate.
- 2. Pick the configuration: we map that to cell option, BMS rating, monitoring and enclosure, and flag trade-offs.
- 3. Sample stage: evaluate samples against your own tests and documentation needs.
- 4. Pilot order: confirm labeling, packaging and document package.
- 5. Repeat supply: lock the specification so reorders stay consistent.

Frequently Asked Questions
Can it replace a lead-acid battery directly?
Usually yes, once three things are checked: the charger has a LiFePO4 profile, alternator charging goes through a DC-DC charger, and the battery box fits the dimensions. See our LiFePO4 vs lead-acid guide.
Are the specifications on this page fixed?
No. The exact cell option, BMS rating, dimensions and documents for your build are confirmed in the datasheet issued with your quotation.
Can you supply it under my own brand?
Yes — case color, logo, labels, manual and packaging are standard OEM options; electrical and monitoring changes are handled as ODM configuration.
Why one 460Ah battery instead of four 100Ah batteries?
One BMS, fewer interconnections and simpler wiring and monitoring. The trade-off is weight and less redundancy; some customers prefer two 230Ah units.
Can it communicate with my inverter?
CAN or RS485 communication can be configured as an option. Protocol compatibility depends on the inverter brand and is confirmed per project.
How is MOQ set?
MOQ is confirmed per project stage — sample, pilot and production — and depends on cells, tooling and branding scope. Logo-only changes usually differ from new-tooling projects.
Which certificates apply to this model?
Certificate scope is confirmed per model and per order (e.g. shipping documents such as UN38.3 / MSDS). Custom changes can affect scope, so we confirm it before quotation.
Can I get cell traceability documents?
Cell traceability documents (cell brand/model, batch information, codes where available) are provided on request and confirmed per project.
Is self-heating standard?
No. Self-heating is available on request and is to be confirmed per project.
