LiFePO4 Battery - CTC LFP128075 Review

LiFePO4 Battery

I am writing a review of several lithium iron phosphate batteries. In this article, I will focus on the CTC LFP128075 LiFePO4 battery

Okay, so I bought the CTC battery for my equipment. Actually, before I did - I pestered SEP LiFePO4 BatteryBatteries’ customer service representative. I called to ask which battery will work for my equipment best. I suggest you do as well, before you buy.

The nice young man I spoke with recommended CTC 12.8v 7.5 AH 96Wh Deep Cycle LifePO4 Lithium Battery - LFP128075. The battery is designed to replace SLA-1270, NP7-12 and UB1270.

I was sold with the following features:

  • A replacement for the standard sealed lead acid (SLA) 12Volts - 7AH battery
  • Half the weight of its counterpart
  • Supposed to last longer, 5x compared to regular lead batteries
  • Low self-discharge rate
  • Environment-friendly
  • Nontoxic
  • Comes with overcharging, short-circuit and over-discharge protection.


It is the lithium technology that has me switch my old conventional batteries with the LFP battery. It’s quite expensive. It costs $103 per unit and $66 per piece if you buy a set of 8.


I have some comments about the features of the LFP battery. It was a perfect replacement for my old SLA battery. The reduced weight was a bonus I didn’t see coming. I was able to carry it quite easily and installed it in any direction I wanted.

Self Discharge and Battery

I used monitors to check the self-discharge rate and for a week of operation, I have no complains. Using a lead battery charger, I was able to get the battery at full charge state in less than 6 hours. But I am thinking of buying a special charger for it. I don’t want to mess up my batteries because of using the wrong kind of charger.

But that’s just me. The fact is, I am able to retain my old lead acid battery charging system. Despite using the charger, I monitored steady charge and discharge from the battery.


As for the safety features that initially had me switch to LFP, the device was only a bit warm at most when charging. I believe that I made a good choice because if it doesn’t overheat, it won’t explode or leak. It will keep my family and myself safe.

CTC did a good job in my opinion with the added protection feature. Charging stops automatically when the battery is disconnected. So, I’m guessing the ads that say it will also stop in case the battery short circuits will be true as well.

Note: CTC LFP128075 can only be used in 12v, 24v, or 36v systems. There are internal BMS controllers that allow a max of 36 volt series but connection only.

In a Nutshell

The battery was well packed, lightweight and obviously well-made. Customer service of both CTC and SEP Batteries made the purchase successful and easy at that. They were patient with my numerous questions. I was able to buy another LiFePO4 Battery.
