The Ultimate Flexibility: G4D Modular Prismatic Battery Platform
Why settle for a standard battery when you can have a custom power solution? Our G4D platform is built on a modular prismatic cell architecture, allowing us to engineer batteries tailored to your exact voltage and capacity needs—from 12V to 48V—quickly and cost-effectively.
The Advantages of a Modular System:
Design Flexibility:
Need a unique size, voltage, or terminal configuration? The G4D platform allows for rapid prototyping and customization, speeding up your product development.
Cost & Scale Efficiency:
By standardizing on high-quality prismatic cells, we achieve economies of scale, passing the savings on to you and guaranteeing faster production times.
One Platform, Endless Applications:
Perfect for powering everything from heavy-duty trolling motors and RVs to specialized industrial equipment and solar systems.
Uncompromised Quality:
Every battery, regardless of configuration, benefits from the safety, stability, and long life inherent in our prismatic LiFePO4 cells.
The LiFePO4 batteries VS Lead-acid batteries:
| Haicen LiFePO4 batteries | VS | Old technology-Lead-acid batteries |
| Stable discharge condition | Low temperature condition | Unstable discharge condition |
| 3,500 times | Cycle life | ＜500 times |
| Around 10 years | Design life | 3 years |
| As little as 3.5 hours | Charging time | Up to 8 hours |
| No memory, opportunity charge | Charge frequency | Must charge after use |
| Multiple built-in protections, high thermal and chemical stability | Safety | Gas inside may cause explosion |
| 85% or more nominal capacity achieved at high working load | Available capacity | Only 30%~50% nominal capacity achieved under high working load |
| Maintenance-free | Maintenance | Regular water-adding and inspection required |
| Pollution-free | Eco-friendly | Lead is a toxic substance, may cause human lead poisoning |
| Extremely low | Energy loss | 15% |
