12V 100Ah LiFePO4 battery

This Group 31 12V 100Ah LiFePO4 battery packs a big punch in a small package. Engineered in a SLA case, but with 100Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery has 2 times the power, half the weight, and lasts 4 times longer than a 100Ah sealed lead acid battery – providing exceptional performance & lifetime value. Combine 2 for 24 Volts or 4 for a 48 Volt system. 100 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.

This Deep Cycle Lithium Iron battery matches the dimensions of group size 31 and can be used as a drop-in replacement for equivalent lead acid batteries within the 31 group size.

100 ampere hours (Ah). Keheng Lithium batteries provide consistent power for all 100 amp hours. KH LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.

Group 31 Lithium Batteries

battleborn 100ah 12v lifepo4 battery ,Lithium group 31 batteries are becoming more and more common thanks to the advancements in chemistry and electronics.

Lithium Iron Phosphate (LiFePO4) group 31 batteries with protective Battery Management Systems (BMS) that monitor battery conditions including voltage, charging/discharging current, temperature, etc. prevent undesired events, often can directly replace lead-acid batteries in marine, automotive, off-the-grid, and other deep cycle applications.

When compared with lead-acid batteries, lithium batteries are 2-3x lighter, can withstand 5-10x more charging/discharging cycles, can provide almost fade-free power regardless of the charge condition, etc., but they are also more expensive than equivalent lead-acid batteries.

Also, lithium batteries must be recharged using dedicated lithium battery chargers or advanced AGM battery chargers that feature dedicated lithium battery charging modes.

Due to their price, lithium Group 31 batteries are used where weight savings are important and when their features justify the price difference – they are commonly used as RV house batteries, as lightweight trolling motor batteries, in the off-the-grid, medical and security applications, etc.

Batteries in series and parallel

The main difference in wiring batteries in series vs. parallel is the impact on the output voltage and the capacity of the battery system. Batteries wired in series will have their voltages added together. Batteries wired in parallel will have their capacities (measured in amp-hours) added together.

Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity. With a parallel battery connection .
