RV and camper van house banks
Replaces a lead-acid bank at roughly one third of the weight, with a usable depth of discharge lead-acid cannot reach.
12.8 V drop-in replacement · B2B and OEM supply
Models: FT-1250 · FT-12100 · FT-12150 · FT-12200 · FT-12300 · FT-12400
Six capacities on one 12.8 V platform, sized to replace lead-acid banks in RV house systems, marine, golf carts, trolling motors and off-grid solar. All models share the same charge profile and support up to four units in series or four in parallel, so a distributor can cover an entire capacity range from a single technical datasheet.
No public price. Quotation is based on model, quantity, application, customisation and delivery requirements.

Buyer decision points
This page is structured around technical review, procurement qualification and project conversion rather than retail pricing.
This page covers a whole capacity range. Quote against a single model code so the terminal, enclosure and current rating on your purchase order match what ships.
Charging must not start below 0 °C; the BMS blocks it to protect the cells. Discharge continues to -20 °C. For cold markets, ask about the self-heating option before you specify.
Recommended · continuous maximum 50 A
Confirm the continuous-current requirement against the final BMS build, and size cable and protection to the peak figure rather than the nominal one.
Up to in parallel
Review total current, busbar and cable sizing, protection coordination, address settings and topology for the specific project.
Protection rating: IP54
This range is rated IP54. Match that to where the battery actually sits — an indoor rating on an outdoor install voids the warranty and creates a safety risk.
Confirm which pack-level and cell-level certificates apply to the exact production configuration and target market before publishing or purchasing.

Application fit
Positioned for distributors, system integrators, installers and OEM brands specifying batteries into their own systems.
Replaces a lead-acid bank at roughly one third of the weight, with a usable depth of discharge lead-acid cannot reach.
50Ah to 100Ah for electronics and accessories, 200Ah and above for trolling motor runtime.
Four units in series for a 48 V drive pack, using the 4S support built into the BMS.
Small cabin, telecom and lighting systems where a 12 V bus is already established.
OEM / ODM capability
This platform can be reviewed for private-label projects and system-integration requirements. Optional functions should be defined before sample production and locked after approval.
Share target quantity, market, application, load and charging details.
Confirm battery configuration, BMS, terminals, housing and documents.
Review product label, packaging and functional requirements.
Assembly, functional testing, aging and final quality checks.
Prepare lithium battery shipping documents and agreed packaging.
Supplier verification
A B2B product page should help procurement teams verify who will build, test and support the battery. Safecloud Energy Inc. was founded in 2007 and operates two plants in henan and anhui, 48,000 m² total, with eight automated production lines, 30+ aging machines, in-house testing laboratory.
Verify cells, BMS, enclosure, wiring and purchased components against the approved configuration.
Review voltage, current, capacity, protection functions and communication according to the inspection plan.
Run configured systems through defined charge and discharge and communication checks before release.
Check firmware, label, terminals, accessories, manuals, carton marks and project-specific details.
Protective packaging with project-approved pallet or carton arrangement suitable for the order and route.
Buyer questions
Start from the load, not the capacity. Send the continuous and peak current, the daily energy requirement and the autonomy you need, and our engineers will map that onto a model code before quotation.
No. This is a drop-in replacement platform with a protection BMS, not a communicating pack. Bluetooth and an LCD display are available as options for state-of-charge monitoring. If you need RS485 or CAN reporting, look at the rack-mount or home ESS ranges instead.
Yes. The BMS supports up to four units in series and four in parallel. Use identical models, matched state of charge and identical cable lengths, and confirm the charger profile before commissioning. Mixing capacities or ages in one string is not supported.
No. Bluetooth, display, communication modules and low-temperature charge protection are options. Confirm what you need during quotation so the BMS, enclosure, wiring and documentation are configured accordingly. This model is rated IP54.

The warranty term is stated in the commercial section of the specification table. Warranty handling, spare-part supply and RMA turnaround are agreed per distribution or OEM contract, and depend on the installation staying within the stated temperature and current limits. For this model: 3 years / ≥ 3,000 cycles, to 70 % capacity retention.
