Why choose LiFePO4 to replace lead acid
Cycle life: Our lithium iron phosphate can achieve more than 6,000 deep cycles, while lead acid may only be around 500. Therefore, the new battery life is 10 times that of traditional lead acid.
100% usable capacity: This is a big advantage. Our 75Ah lithium iron phosphate battery can use almost 100% of its capacity. For a 75Ah lead-acid battery, you may only be able to use 50%-60% of its nominal capacity, which is about 37-45Ah.
Maintenance: Our lithium iron phosphate batteries are completely maintenance-free, so you can just install them and forget about them. However, many lead-acid batteries require regular checks of the liquid level and watering.
Safety: Our lithium iron phosphate batteries have built-in intelligent BMS, providing multiple protections such as overcharge, over discharge, over current, over temperature, short circuit, etc. Lead-acid batteries have the risk of acid leakage and flammable hydrogen precipitation.
Charging efficiency: The charging efficiency of lithium iron phosphate is over 95%, while that of lead-acid is about 80-85%, which means less energy loss during charging.
What can 12V 75Ah deep cycle battery work
Hongyitai 12.8V 75Ah lithium iron phosphate battery has obvious advantages. It is often used in recreational vehicles, RVs, ships, yachts, solar energy, off-grid energy storage, backup power, UPS, and golf carts. For these scenarios that originally used 12V 75Ah lead-acid batteries, it is an ideal or even the best replacement upgrade solution.
How to upgrade from AGM to lithium iron phosphate
Our 12V 75Ah lithium ion battery is designed according to standard size, which can be used as a drop-in replacement without requiring you to make major changes to the installation location. However, this also requires you to measure the size of the traditional battery again to confirm whether it matches.
The terminals on your new 12V 75Ah battery have bolt holes that match your existing cable glands, allowing you to connect your original cables directly.
The best option is to use a charger designed specifically for lithium iron phosphate batteries, with a charging current of about 30 A. You cannot directly use an ordinary lead-acid charger, which may not have a balanced charging function.
Our battery supports up to 12 batteries in series and 4 batteries in parallel. Before combining, it is best to choose batteries from the same batch, the same manufacturer, and with capacity and internal resistance differences within a certain range.
FAQs for 12V 75Ah lithium ion battery
Yes, in terms of chemical properties and structural design, lithium iron phosphate batteries are much safer than lead-acid batteries. They have very good thermal stability and are not prone to thermal runaway, leading to combustion or explosion.
We recommend that you use a dedicated charger for lithium iron phosphate and abandon the traditional charger. Our lithium batteries can be delivered with the corresponding charger.
The actual life of lithium iron phosphate batteries is very good. In terms of the number of cycles, our Hongyitai 12V 75Ah battery can reach 6,000 times or more under 80% depth of discharge (DOD) conditions.
