12V 80AH LiFePO4 series connection capable battery

This 12V  80AH LiFePO4 series connection capable battery packs a big punch in a small package. Engineered in a SLA case, but with 80Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery has 2 times the power, half the weight, and lasts 4 times longer than a 80Ah sealed lead acid battery – providing exceptional performance & lifetime value. Combine 2 for 24 Volts or 4 for a 48 Volt system. 80 Amp hours of capacity provides a full day of power for high amp draw electronics like Garmin fish finders, ice augers, or anything where you need a longer run time.

Best Battery IP65 Waterproof Box

These ip65 waterproof battery box are made from hard plastics that ensure better durability and are strong enough to protect items kept inside them.

Lightest Battery

The energy ratio of lithium iron phosphate battery is 2 times that of lead-acid battery, it is the best lead-acid replacement battery, its weight is only half of lead-acid battery, it is currently the lightest lithium-ion battery.

The primary function of the BMS is to protect the battery cells from damage caused by being overcharged or over-discharged. Additionally, the BMS calculates the remaining charge, monitors the battery’s temperature, monitors the battery’s health and safety by checking for loose connections and internal shorts. The BMS also balances the charge across the cells to keep each cell functioning at maximum capacity.

If it detects any unsafe conditions, the BMS shuts the battery down to protect the lithium-ion cells and the user.

Battery management systems are critical in protecting the battery’s health and longevity but even more important from a safety perspective. The liquid electrolyte in lithium-ion batteries is highly flammable.

So, these batteries need to be operating optimally and within safety limits at all times to prevent a fire.

Batteries In Series And Parallel

12V 80AH LiFePO4 series batteries can be connected in a mixture of both series and parallel. This combination is referred to as a seriesparallel battery. Sometimes the load may .

Batteries can either be connected in series, parallel or a combination of both. In a series circuit, electrons travel in one path and in the parallel circuit, they travel through many branches. The following sections will closely examine the series battery configuration and the parallel battery configuration.


  • The voltage can be expanded from 12V to 48V to power various products.
  •  Support 4units in series connection, or 10units in parallel connection.
  •  LCD display optional, real-time understanding of battery voltage and capacity.
  •  100A continuous output voltage can continuously charge big-power devices.
  •  The intelligent BMS system can accurately control the battery to improve the lifespan, no explosion, no fire.
  •  Drop-in replacement for heavy lead-acid(AGM / GEL) battery,1/3weight but same capacity.
  • 2000times cycle life@100% DOD , 7000times cycle life@50% DOD , 10 years design lifespan.
  • Maintenance-free, fully sealed, and waterproof.
