Features

  • LiFePO4 Battery with Grade A Cells LiTime 12V 400Ah Lithium Iron Phosphate (LiFePO4) batteries have exceptional quality since they are assembled by Automotive Grade LiFePO4 Cells with UL Testing Certificated, which make them higher energy density (37.12 Wh/lb), more stable performance, greater power, and excellent 3% self-discharge rate.
  • 1/3 Lightweight & 10-year Lifetime LiTime LiFePO4 battery can run 4000-15000 cycles (10-year lifetime), which is quite superior to lead acid battery with 200~500 cycles (3-year lifetime). Plus, our 12V 400Ah lithium ion battery weighs 86.2lbs, only 1/3 the weight of lead acid battery at the same capacity. Besides, our LiFePO4 battery case is IP65 level waterproof, and you can move it by grabbing the handles on both sides, which will set you free from worrying to install indoors or outdoors.
  • 100% Protection from 250A BMS LiTime 12V 400Ah LiFePO4 battery has built-in 250A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current (250A), over temp (167 F) and short circuit. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged.
  • 3200W Power & Fast Charging With a 3200W high load power, our 12V 400Ah LiFePO4 battery is perfect for RV, marine, boat, fishing, camping, solar home, trolling motor, and off-grid applications. It can realize 100% SOC & DOD, providing astronomical boosts in lifetime compared with lead-acid battery. A 12V 80A/40A LiFePO4 battery charger is recommended; the lithium battery will be fully charged within 5hrs/10hrs.
  • Max. 1600Ah Expandable CapacityLiTime 12V400Ah LiFePO4 battery supports to be connected in series & parallel, and max. in 4S4P for a 51.2V 1600Ah battery system to get 51.2kW output power and 81.92kWh usable energy. They can definitely meet your need for building your battery system, and perfect for home energy storage. Besides, the BMS with equalization function to control the consistency of the battery cells, which will extend the batteries lifespan.

    • Forget AGM and lead acid - this is what you want to run your trolling motor
Style: 12V100Ah
First of all, it has more amp hours when compared to an AGM or lead acid of the same rating. How is that possible? Very simple: you should only run an AGM or lead acid down to 50% capacity or you will shorten its life. You can run this down to 20% without degradation. So a 100 amp/hr AGM or lead acid has 50 amp/hrs usable. This has 80 amp/hours usable. That’s a big difference! Next, at 50% capacity, both AGM and lead acid will give a noticeable drop in power of your motor. With this battery it’s about the same at 50%. And the weight. At 25 pounds this thing is no big deal to pull out of a storage well or compartment. I don’t store the battery on the boat, so this is a quite an advantage. After a season of frequent use, this battery shows no loss of capacity. It runs longer, performs better and weighs less. I only ever got 2-3 seasons out of lead acid, if this thing only accepts 1/2 of its advertised charges it will last 4-5 times longer than lead acid. ... show more

    • Exceptionally Good for It's Price Point
Style: 12V100Ah
I bought two of these batteries (12V 100ah). First ordered one to test, satisfied I ordered a second. Both Received On-Time, Good Packaging. Extra terminal bolts provided each. Documentation is good, clear values for User programmed chargers. These are setup in series now to form a 24V 100ah battery pack. I opted to pay more by having two batteries rather than one 24V battery for a few reasons. As stated above, I was concerned with the quality and wanted to test one battery before doubling down for twice the expense. Second, these batteries have a battery management system which is internal to the battery. If it goes bad, chances are the battery will be useless. Having two go bad is unlikely. So I can always reconfigure my system to run from the good 12V battery. Finally, I have a lot of 12V stuff and having a pair of very good 12V batteries gives me more options. These batteries are well built, case seems generic but sturdy. Especially happy with the Terminals, they seem very firmly mounted to the case and hold connections tight. I've run several capacity checks on this, but the only full capacity test I made would be characterized as a .1C test. That is a constant discharge of 100watts, but in my case it was a refrigerator with defrost so when it did run it was about 110watts and about 330watts during the defrost cycle. I was expecting it to run about 39hours but it only made 32 hours. However, then I worked in the inverter efficiency (90%) and the vampire power used by the inverter even when it is not generating wattage. I did several different discharge tests and always got above 95% of the rated watt/hours. That is excellent considering the price point on these batteries in comparison to other similar batteries. I DO NOT recommend any PWM charger with these. I tried charging the battery with a Renogy Voyager and the pulses exceeded the max voltage causing the Battery's Management System to disconnect. Even though this Renogy charger has a LifePO4 setting. I contacted Renogy they were no help, I also contacted AmperTime and the good news is they actually responded. But I knew what the problem was and it simply was not a battery or Battery Management System issue. Needless to say I bought an MPPT charger, EPEVER Triron and it works great. But that is for another review. Couple more notes. I am shocked at how lightweight this battery is, they weigh about a third of what a typical flooded battery would. Every time I pick them up I am surprised by their lightweight. I am sure RV people will appreciate this. The max voltage I got on these batteries is 13.5V after it settles, I was expecting 14.4V. Without making this longer, don't worry about it. It is a weird charge curve and 13.5V is basically 99% charge. My discharge test confirm these batteries will perform to there approximate 100ah rating. In Summary, very happy, highly recommended and I did buy two, perhaps get more in the future. ... show more

First impressions, 1.) Solid product but much lighter than you would imagine. 2.) Quality boxes that they were shipped in 3.) Customer support!!! and I can't express this enough Like most people I am using these batteries in a hybrid solar system for my home. After alot of back and forth and many excel sheets I settled on starting with a 24 VDC battery bank. I ordered 2x of their 300ah 12vdc batteries and planned on running them at 24vdc. So over the course of a few weeks everything started coming in and I got to work. Here are some things to look out for and why these batteries are my new go-to instead of AGM. Alot of people do not understand the chemistry involved in the PO4 batteries and steps that need to be followed for the battery to do what it does best and that's store lots of energy. 1.) These have to ship with a low charge and will need to be charged independently if setting up a large battery bank ( single battery system no need to worry) 2.) After each battery has been if fully charged you connect them in series and let them sit for roughly 24 hours. ( I left my mppt and shunt on so there was a light load during the balancing of the cells ) 3.) They cannot be charged when cold. These batteries have a BMS but it is a modified BMS so that you can discharge the batteries in the cold but for all that is good please make sure your charging system HAS a LOW temp cut off for charging. And or do what I do and have a sperate BMS for the battery bank and let the batteries manage them selfs with in the bank. So since I was not doing an off the shelf setup I had a lot of questions about voltage and charging characteristics of these batteries. There was not much online so I just decided to reach out to customer support and was put in contact with Panddy and it has been by far one of the most productive and useful chats with a customer support rep and it was on the First try. I didn't have to go through 3 or 4 associates before I got the answers I was looking for and they had me up I'm running within an hour. I will update with more information as I get to test these batteries but to break down the setup, Victron for inverter/charger and mppt/BMS, Ampere time for the batteries, and last Newpowa 9bb solar panels. ... show more
