The HSS Energy's China 12V 20Ah LiFePO4 Battery Pack is easy to judge when four figures are known: 12.8V nominal voltage, 256Wh energy, 20A continuous discharge and a 170 × 77 × 181mm case. If those figures match the equipment, the next checks are the charger, short-term surge current and terminal layout. HSS Energy can then prepare a sample or bulk quotation around the actual installation instead of offering a generic battery that may not fit.

Product appearance and headline specifications
The 12.8V 20Ah lithium battery format gives designers useful runtime without moving to a large enclosure. It suits solar lighting, security and monitoring equipment, portable instruments and selected backup loads. A quick runtime estimate starts with device wattage and required operating hours; surge current and temperature are checked separately.
A 20Ah LiFePO4 rechargeable battery is rated at 20A continuous discharge and 40A peak current. Recommended charging is 14.4V and the recommended discharge cutoff is 10.4V. Compare these limits with the equipment load and charger profile; provide a wiring drawing when the terminals must match an existing product.
The 4S4P cell assembly, busbars, insulation materials, BMS and top terminals form the working structure of this 26700 LiFePO4 battery pack. The plastic enclosure keeps the unit compact and easy to integrate. It is intended for protected installation; outdoor exposure, heavy vibration or waterproofing requires a separate enclosure solution.
Internal component illustration; final production structure follows the approved specification
For a 12V solar lighting battery project, lamp wattage and night-time runtime are the main sizing inputs. Monitoring and backup equipment needs both standby and active-load data. Portable systems are usually decided by space, weight and connection layout. These are application directions; final compatibility depends on the equipment specification.
HSS Energy handles incoming inspection, pack assembly, electrical testing, final inspection and packaging as separate checkpoints. For a 12V backup power lithium battery order, the approved sample becomes the production reference for voltage, capacity, BMS limits, polarity, dimensions, label and packaging. The workflow covers incoming inspection, assembly, electrical testing, final inspection and shipment packing.
Quality and delivery workflow
To quote the 12V 20Ah LiFePO4 Battery Pack accurately, send the application, quantity, normal and peak current, charger details, installation space and destination. Project options include RS485, CAN or Bluetooth communication, private labels and order-specific packaging.
OEM/ODM enquiry information
12V is the common product-class name. The specified nominal voltage is 12.8V because the pack uses four LiFePO4 cell groups in series.
Not automatically. Compare the charger, cutoff settings, continuous and surge current, terminal arrangement, compartment size and equipment control logic before replacement.
Only if its charging profile matches the approved LiFePO4 settings. The recommended charge voltage is 14.4V, with 14.6V as the stated upper cutoff.
Yes. RS485, CAN or Bluetooth can be supplied as project options.
The listed standard is 20A, with a 40A peak-current specification.
Send the application, load data, runtime target, charger, available space, connection drawing and environmental conditions. HSS Energy will use them to define the sample specification.
Xiamen HSS Energy Technology Co., Ltd. makes lithium battery packs and energy storage products. Established in 2023, the company is backed by partners with more than ten years of battery-industry experience. Multiple production bases in China support prototypes, OEM/ODM projects, batch production and export orders. We agree on one workable specification, build the sample to it and keep the production order consistent with that sample.
12V 20Ah LiFePO4 Battery Pack pricing depends on the confirmed electrical configuration, quantity, interface, communication, labeling, packaging and destination. Send your equipment requirements and expected order volume to receive a configuration review and quotation from HSS Energy.
