Use it where a lead-acid block is replaced every two years. The 10A BMS limits it to small loads: lights, cameras, pumps under 120W and standby power. For a trolling motor or an inverter above 150W, move to the 12V 100Ah model.
The 12.8V 10Ah LiFePO4 battery provides 128Wh of rated energy for compact auxiliary, fish-finder, lighting, CPAP and small backup loads. It supports up to 10A continuous discharge, 5A recommended charging, IP65 protection and a 151 × 66 × 95mm enclosure weighing approximately 1kg. It is intended for verified deep-cycle installation projects.
Common FAQs
The model is intended for compact auxiliary, fish-finder, lighting, CPAP and small backup loads. Confirm system voltage, load current, required operating time, charger profile, installation space and environmental conditions before selection. Rated energy is 128Wh, but actual runtime depends on the complete load and system efficiency.
Start with 128Wh of rated energy, then apply the selected depth of discharge, inverter or conversion losses, temperature effects, cable losses and reserve capacity. Divide usable watt-hours by the measured load in watts for an initial estimate rather than using Ah alone.
Use a charger compatible with the model's published voltage range. The technical table lists 2A standard, 5A recommended and 10A maximum charging current. Confirm charging voltage and current before installation.
The model publishes up to 10A continuous discharge and 128W continuous power. Check inverter efficiency, surge current, cable size, fuse or breaker rating and BMS limits. Do not size the load from Ah capacity alone.
Replacement requires checking nominal voltage, charger profile, alternator or DC-DC charging, inverter settings, low-voltage protection, terminals, physical dimensions and maximum current. A similar case size does not confirm electrical compatibility.
Only when the selected model and BMS support the planned configuration. Use identical batteries with matched age and state of charge, equal cable paths and correctly sized protection. Confirm maximum series or parallel quantity before installation.
The published charging range is 0°C to 50°C and discharge range is -20°C to 60°C. The enclosure is rated IP65. IP65 does not permit continuous submersion, and charging below 0°C is not supported without suitable low-temperature protection.
Documentation for UN38.3, CE, RoHS and FCC review is available, with a 5-year warranty. Confirm destination-market requirements and provide the application, quantity, charging system, installation environment and destination with the inquiry.
