Q & A
12V 50Ah Lithium Battery
Compared with lead-acid batteries, Ampere Time LiFePO4 battery have the following characteristics:
Ultra-Safety /
Ultra-Light Weight /
Long cycle life /
Uncompromised Quality
【Similar Usable Energy but 5 Times Faster Charging】
Our 12V 50Ah lithium battery has 640Wh energy (12.8V×50Ah×100%DOD=640Wh ), which is close to the real energy of 12V 100Ah lead-acid battery (12V×100Ah×60%DOD=720Wh), as the depth of discharge (DOD) of lead-acid is about 60%. It means 12V 100Ah lead-acid battery can run an 80W load nonstop for 9hrs while 8hrs as our 12V 50Ah battery can. And it takes 10-20hrs to fully charge a 100Ah lead-acid battery while 1-2.5hrs of our battery. How efficient!
【Top Protection & 8 Times Lifespan】
Ampere Time LiFePO4 battery is made of automotive grade LiFePO4 cells, which has higher energy density, more stable performance & built-in BMS. Compared with the 200-500 cycles and 3-year lifespan of lead-acid battery, our battery has more than 4000 deep cycles and a 10-year lifespan, which means that the lifetime of one of our 12V 50Ah LiFePO4 battery is equivalent to the total lifetime of 3-8pcs 12V 100Ah lead-acid batteries. What a huge difference!
【4 Times the Value for Money】
Ampere Time LiFePO4 battery ensure you 5-year warranty while the best-selling lead-acid battery is only 1 year. In terms of lifetime use, the value of our 50Ah battery is almost 4 times than 12V 100Ah lead-acid battery. For example, the cost per use of our battery is $0.069（$219.99/5-year warranty/640Wh=$0.069), but $0.294 of a 12V 100Ah lead-acid battery ($211.57/1-year warranty/720Wh=$0.294). Data shows that buying our battery is the best investment for your money.
【1/6*Lightweight & More Flexible Applications】
Ampere Time 12V 50Ah LiFePO4 battery has an extremely lightweight of 11.57lbs, only 1/6 of a 12V 100Ah lead acid battery (about 60lbs), and a 10-year-old child may be easy to tow or move. Meanwhile, our battery has various connections in parallel (max. capacity of 200Ah) and series (Higher voltage of 24V, 36V, 48V), it’s ideal for home back up system such as security devices, lights, solar and outdoor activities like boat, camping, trailer, etc.
【Fast Delivery & Outstanding Service】
We are committed to providing you with satisfactory service. Fast delivery because the battery will be shipped from our local warehouse in Los Angeles, California or Dallas, Texas. Professional technical support, humanized return policy & customer service as we provide easy-to-understand operation manuals & online services with quick feedback within 24hrs. If you have any questions, please feel free to contact us, we will do our best to support you.
Cut 50 lbs or more off the weight
Compared with the 60lbs of a 100Ah lead-acid battery, Amperetime 50Ah LiFePO4 battery is only 1/6*(11.57lbs) the weight.
5X faster charging
It only takes 1-2.5hrs to fully charge the LiFePO4 battery while 10-20hrs of the 100Ah lead-acid battery, greatly saves your time.
Run your trip faster
LiFePO4 battery supports a maximum of 1C discharging current making it not suitable to be used as a starting battery or power a trolling motor. If you need to use it on these scenarios, please feel free to contact seller.

FREQUENTLY QUESTIONS ASKED
Q:
Can Ampere Time LiFePO4 batteries be mounted in any position?
A:
Yes, Ampere Time lithium battery is free from lead-acid battery safety issues such as battery leakage and battery corrosion, so it is perfectly fine to place the lithium batteries in any position. (
but it could not be mounted upside down
)
Q:
How long is the warranty?
A:
We provide a five-year warranty (for most of the battery products) for the poor performance of battery products when used correctly following the product manual instructions. The warranty is in effect from the date of purchase by the user.
Q:
How can I check my battery’s remaining power?
A:
Most of our customers will use a multimeter to check the voltage of their Ampere Tim LiFePO4 batteries. And you could roughly estimate your battery’s remaining power by its rest (open-circuit) voltage. Based on the characteristics of LiFePO4 batteries, the voltage measured by all LiFePO4 batteries during charging/discharging is not the real voltage of the battery.
Therefore, after charging/discharging and disconnecting the battery from the power source, the voltage of the battery will gradually drop/increase to its real voltage.
If you need to test the real voltage of the battery, please disconnect all the connections to the battery and test its voltage after putting it aside for over 30 mins.
Here take 12V 100Ah battery as an example, please refer to below SOC:
Capacity—Voltage
100%—13.5V
99%—13.4V
90%— 13.3V
70% — 13.2V
40% — 13.1V
30% — 13.0V
20% — 12.9V
10%—12.8V
1% —10.8V (recommend low voltage disconnect voltage)
0% —9.5V
Q:
Are Ampere Time batteries waterproof?
A:
All of our Ampere Time LiFePO4 battery has an IP65 protection class, which sets you free from worrying to install it indoors or outdoors. But when charging or discharging the battery, please be careful not to let the post bolts or terminals come into contact with water, as this may damage the battery.
Q:
Can Ampere Time batteries replace my lead-acid batteries?
A:
Ampere Time LiFePO4 battery is considered the perfect replacement battery for the AGM battery. The LiFePO4 battery will become the majority used in the future as it has superior performance compared with other AGM batteries. You can use it to replace your lead-acid batteries and start to enjoy a free & fruitful life.
Q:
Can I connect Ampere Time batteries with AGM batteries?
A:
We do not suggest you connect Ampere Time lithium iron phosphate (LiFePO4) batteries with AGM batteries, as they are two different types of batteries and their charging and discharging are very different.
