IP64 drop-in replacement · B2B and OEM supply
Models: FT12100-B · FT12200-B · FT-24200-B
The FT-B series is the sealed version of our lead-acid replacement platform. Where the standard ABS range is rated for clean indoor installation, FT-B uses a metal case at IP64 for dust ingress and splashing water, which is what RV underfloor bays, boat lockers, agricultural machinery and outdoor cabinets actually require. Three models cover 1.28 kWh to 5.12 kWh on one charge profile family.
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 three models across two voltage platforms. Put a single model code on the purchase order so the enclosure, terminal and current rating that ship match what was quoted.
IP64 covers dust ingress and splashing water from any direction. It is not immersion-rated and it is not a substitute for an enclosure in a permanently wet location. Confirm the actual mounting position before specifying.
Recommended · continuous maximum 100 A continuous
Each model carries a 10-second peak at twice its continuous rating for motor and compressor inrush. Cable, fusing and busbar selection must be based on the peak figure.
Up to in parallel
Charging must not begin below 0 °C. Discharge continues to -20 °C. For cold markets, raise the low-temperature charge cut-off or self-heating requirement during quotation, before sample approval.
Protection rating: IP64
The FT-B series ships as a protection-BMS platform. If the project needs RS485 or CAN reporting to an inverter, specify it at quotation stage so the BMS and wiring are built accordingly.
Pack-level documentation covers CE, FCC, UN38.3 and MSDS. Confirm which certificates name the exact production configuration and destination market before publishing or purchasing.

Application fit
Positioned for distributors, system integrators, installers and OEM brands replacing sealed lead-acid banks in exposed installations.
Underfloor and external-bay installations where dust and road spray rule out an ABS-cased indoor battery.
Lockers and engine compartments needing a sealed enclosure, with peak current headroom for windlass and bilge loads.
12 V and 24 V buses in cabinets, huts and remote sites where the enclosure sees temperature and dust cycling.
Sprayers, feeders, gate systems and access equipment replacing sealed lead-acid with a longer-life pack at a third of the weight.
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, inverter model and charging profile.
Confirm cell configuration, BMS, communication protocol, enclosure and document scope.
Review label, packaging, firmware and functional requirements before mass production.
Assembly, functional testing, aging and final quality checks against the approved configuration.
Prepare lithium battery export documents and the agreed export packaging.
Supplier verification
A B2B product page should let a procurement team verify who builds, tests and supports the battery. Safecloud Energy Inc. was founded in 2007 and operates two plants in Henan and Anhui, 48,000 m² in total, with eight automated production lines, 30+ aging machines and an in-house testing laboratory.
Verify cells, BMS, enclosure, wiring and purchased components against the approved configuration.
Check voltage, current, capacity, protection functions and communication against the inspection plan.
Run configured packs through defined charge, discharge and communication cycles before release.
Confirm firmware, label, terminals, accessories, manuals and carton marks.
Protective packaging with the project-approved pallet or carton arrangement for the agreed route.
Buyer questions
FT-B uses a metal enclosure rated IP64 rather than an ABS case, and carries higher continuous and peak current ratings at the same nominal capacity. Choose FT-B when the installation position is exposed to dust or splashing water.
Send us the intended topology at quotation stage. Series and parallel limits depend on the BMS build for your order, and we confirm them per configuration rather than publishing a blanket figure. Use identical models at matched state of charge with identical cable lengths.
Not as standard. Communication is available as a configured option — specify the protocol and the target inverter at quotation so the BMS is built and tested for it.
It is the current the pack will supply for motor starting and other inrush events, at twice the continuous rating. It is not a duty-cycle rating; sustained operation must stay within the continuous figure. This model is rated IP64.
Pack-level CE, FCC, UN38.3 and MSDS. Tell us the destination market and we will confirm which certificates name the exact configuration you are ordering before you place the order.
Model code, quantity, target market, continuous and peak current requirement, optional functions, logo or label files, documentation scope and target delivery date. For this model: 5 years / 6,000 cycles, to 70 % capacity retention.
Request for quotation
The model list is attached automatically. Share the technical information needed for a useful quotation rather than only asking for a unit price.
Three IP64 drop-in models on one platform: 12.8 V 100 Ah, 12.8 V 200 Ah and 25.6 V 200 Ah. Built as a direct lead-acid replacement for RV, marine, off-grid and backup systems where the battery sits in a dusty or splash-exposed location, with a 10-second peak rating at twice the continuous current for compressor and motor starting loads.
