I started this whole process with a couple AGM batteries but quickly realized I wanted something with a much larger lifespan. I also wanted more capacity, so I went with a Chins 12v 300ah battery.

Here are also the batteries that I've come across for review that I recommend.

GoKwh 12v 100ah Lifepo4 Battery

GoKwh has a 12v budget battery that can perform. It passed the capacity test and I was able to pull over 200A! It does have a weird LCD display embedded in the battery case which is good to see voltage, but I wouldn't rely on the battery capacity percentage since it's not a true shunt monitor.
I my opinion this battery has some flaws so I don't want to promote it.

Here is the updated User Manual!

Here is an updated battery that really fits the bill! This one I can definitely say is a good product. It has low temp protection and Bluetooth. Link to Battery

Ampere Time 12v 50ah Lifepo4 Battery

This battery is perfect for replacing a 12v 100ah Lead Acid Battery. It's super light and has the same capacity!

Here is the official Ampere Time Website!

I did a second review on this battery just to show how light and powerful it is!

  • 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!
  • 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!
  • 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
  • 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.
  • 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
  • This 12V 50Ah battery is suitable for energy storage rather than start-up and supports a max. discharge current of 1C. Recommended: 12V 50Ah battery for 20~30lbs thrust trolling motor. (For recommendation on other models of trolling motors or starter batteries coming later this year, please feel free to contact Ampere Time.)
