$229.00 – $916.00 (-12%)
Please identify the Positive and Negative terminals of cells before installation. (The Black one is Positive, the Khaki one is Negative)
Why LiFePO4?
Of all the lithium options available, there are several reasons why LiFePO4 has been selected as the ideal lithium technology for replacement of AGM DEEP CYCLE. The main reasons come down to its favourable characteristics when looking at the main applications where AGM DEEP CYCLE currently exists. These include:
- Similar voltage to AGM DEEP CYCLE (3.2V per cell x 4 = 12.8V) making them ideal for AGM DEEP CYCLE replacement.
- Safest form of the lithium technologies.
- Environmentally friendly –phosphate is not hazardous and so is friendly both to the environment and not a health risk.
- Wide temperature range.
Please note that these cells don’t have bolt holes on the terminals. We use laser welding machine to connect busbars to each cells. With this, please choose how you would want us to weld the busbars.
Kindly read the description below for sample photos of how these cells are stacked together. We can pack them if 4 cells, or more. Unless you have a preferred set-up, please let us know either by calling us or email. Installing of bus bars, packing & taping these cells are FREE of charge.
Warranty: None.

Battery Cells Features:
- 1 cell has 200AH 3.2V (4 cells = 200AH 12.8V total)
- Bigger cells mean better safety and more power
- Safety Pressure Release Valve
- Standard new safety technology for high quality batteries.
- Prevents explosion caused by excessive internal pressures due to overcharging, short circuit, excessive temperature, battery deformation or puncture.
- Safety valve on top if a very important for explosion-proof barrier. When pressure inside the battery is build up, the safety valve opens to avoid explosion.
- No Memory Effect
- Rechargeable batteries work under conditions that are often not fully discharged, and the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. There are memories like nickel-metal hydride and nickel-cadmium batteries, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used with charging, no need to discharge and recharge.

The purchase was simple but my complaint was that I received nothing by way of conformation from you that it had even been processed. It fact, the first conformation was a couple of days later from the courier saying the item was out for delivery that day. An email telling me what was going on would have been good.
Noel (store manager) –
Thanks for your feedback, we truly appreciate it! Regarding the email confirmation, we are sorry about that. We have checked it with our developer and found out that in December, there were issues with our SMTP server which caused some problems in our web email automated responses and/or order updates. Beginning of this year, we have already fixed the issue and everything is working normally.
