105 Ah with 12V nominal voltage is not the same as 12V 105 Ah with 12.8V nominal voltage. Both will work just fine in a 12 volt system. Nominal voltage is the average output voltage of the battery. The formula used to determine watts is watts = amp hour x nominal voltage. With 3 times the life!
(1) of AMPS Group 31 105 Ah Lithium. AMPS lithium battery can be discharged 100% without damage.
50% is the maximum recommended discharge. For AGM / lead acid batteries per Lifeline AGM lead acid tech manual. (2) of Lifeline GPL-31T AGM.54 cents per watt =. Voltage stays at 13.2 to to 12.8 volts throughout discharge cycle (up to 80% discharge) means more power! Equipment, motors, pumps, refrigeration, etc. 100 Amp BMS means battery is capable of taking a 100 amp charge or discharge. This is important because most alternators can produce 80 to 100 amps when charging. AMPS 105 Ah battery can be discharged up to 100% which means you can safely use 105 amp hours of energy.
Lead acid batteries should not be discharged below 50% or it will significantly reduce the life expectancy which means that a 105 Ah AGM lead acid battery has only 52.5 usable Amp Hours! (1) AMPS Group 31 105AH Lithium battery weighs 31 lbs.(1) Lifeline GPL-31T AGM battery weighs 64 lbs. (2) Lifeline GPL-31T AGM batteries weigh 128 lbs. Lithium batteries have a 99% charging efficiency.
Every amp that goes in is stored. The BMS allows constant voltage and constant current.Constant voltage is up to 14.6 volts. Constant current is the incoming amps, the recommended current for AMPS 105 Ah lithium battery is 30 amps. The BMS monitors the charge cycle and cuts of the charge when the battery is full. The BMS prevents over charging. A fully discharged AMPS 105 Ah lithium battery can be fully charged at 30 amps in under 4 hours!
AGM / lead acid batteries have a charge efficiency of 85% which decreases as the battery ages. 15% of the charging amps is lost to the chemical conversion and hydrogen gas production.
AGM / lead acid batteries have an initial high amp bulk charge for the first 80% of battery Ah capacity and then throttles down the absorption stage amp input for the last 20% of the battery Ah capacity. This means that the battery will take a long time to fully charge. Imagine going to bed with 13 volts and waking up with 13 volts after running the freezer all night.
Imagine not having to run a generator to charge up the battery bank, daily, weekly or maybe ever. Imagine never having to move a battery ever again.Imagine really being able to rely on just solar and wind to keep the battery charged. Imagine having the same amount of energy in ½ the space and ½ the weight. Imagine have twice the power in the same amount of space. What is peace of mind worth? Some offers are battery cells only - you need a BMS (battery management system) to protect the cells from.
Charge/discharge which will damage them. You need a quality BMS that will handle the maximum combined load of all that stuff you turn on.
A good quality BMS will handle periodic excessive loads but it will stress the BMS and. The BMS determines the charge/discharge capacity of a battery. A lithium battery with a. 50 amp BMS has a.Maximum charge/discharge of 50 amps. Maximum charge/discharge of 100 amps and so on. Most heavy duty alternator and charging systems found in automobiles and boats will exceed 50 amps.
AMPS Lithium Iron Phosphate batteries provide a quality, built-in BMS. Simply, a 12 volt nominal is a battery that has an average discharge voltage of 12 volts. Lead acid batteries are nominal 12 volts and at a 50% discharge are around 12.2 volts. AMPS Lithium batteries have 12.8 nominal.Maintain a discharge voltage of over 12.8 volts throughout the majority of the discharge cycle. Some lithium batteries offer a 12V nominal. Not all lithium batteries are the same. The BMS (battery management system) limits the charge and discharge abilities of the battery. The continuous charge or discharge amperage rate indicates the the BMS capacity. Lithium iron phosphate batteries are a popular way to power recreational and commercial boats, RVs, solar energy systems and other applications that require reliable, long lasting, quick charging and safe batteries. Although it costs a little more upfront, lithium provides superior longevity, efficiency and safety benefits compared to traditional, lead acid batteries. In the long run, lithium batteries cost less with the added benefit that you will not need to replace them every 3 to 5 years. Lithium batteries also maintain a consistent, higher discharge voltage over the course of the discharge.
50% DOD (depth of discharge) = 12.8 or more. Whereas the discharge voltage in lead acid batteries drops with the state of charge (50% DOD = 12.2V or less, 80% DOD = 11.7V or less - per Lifeline AGM lead acid manual).Lead based batteries vary in how long they last. It can be anywhere between 300 to 1000 cycles. Quality brands like Trojan and Lifeline Lead based batteries are not cheap. They cost more because they are made of better materials and have a longer life.
With up to 1000 cycle life, these quality AGM batteries can offer years of service. However, lead acid batteries should not be discharged below 50% or it will significantly reduce the life expectancy of lead acid batteries. All batteries have a lifetime holding capacity for a finite amount of energy. Lithium batteries just happen to be 5 to 10 times that of lead acid batteries.
Lithium batteries are perceived to cost too much. If you put an AMPS Lithium 105Ah Group 31 battery next to a Lifeline AGM Group 31 battery, they look a lot alike. That is where similarities end. Provides 105 Ah usable Ah and total energy of 1344 usable watts. The BMS allows the battery to be discharged 100% without damage.(2) of Lifeline Group 31 105 Ah. 105 Ah usable Ah and total energy of. 50% is the maximum recommended discharge for lead acid batteries. (1) of Lifeline Group 31. The Lifeline Group 31 battery will last a maximum of 1000 cycles (generally less) which means that the battery will need to be replace 3 times (or more) of the same life as a lithium. That is moving a lot of batteries. A single AMPS 105 Ah lithium battery can be discharged up to 100% providing the more energy as (2) AGM batteries. If the lithium battery was discharged 100% every day for 365 days for 10 years, that is a total 3650 days = 3650 cycles. Lithium batteries can last 3000 to 5000 cycles.

Lithium batteries are hassle free. AGM batteries are VLRA (valve regulated lead acid) and can vent explosive hydrogen gas when charged. Lithium batteries do not vent gas and can be kept in sealed environments.
