High-Capacity Energy for Demanding Applications
Our Group 49 LiFePO4 battery delivers robust power in a compact cube form factor. Designed as a direct lead-acid replacement, it provides extended runtime for large golf carts, RVs, and marine use. Experience reliable starting power and deep-cycle performance with zero maintenance and a decade-long lifespan.
Benefits of Haicen Group49 Batteries:
Compact High-Capacity Design:
The Group 49 cube format offers superior energy density, providing substantial power for demanding applications without excessive size.
Perfect Lead-Acid Replacement:
Directly replaces traditional Group 49 batteries, delivering significantly longer runtime and deeper discharge capability.
Maintenance-Free Reliability:
Fully sealed construction with built-in BMS protection against overcharge, over-discharge, and short circuits.
Enhanced Cycle Life:
3,000+ deep discharge cycles provide years of reliable service, far exceeding lead-acid performance.
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% |
Key Points for Quality control:
Cell match: More strict cell matching standard, the difference of lnternal resistance is 1mΩ and voltage is 5mV.
Automatic cells welding: Cells are assembled by Automatic welding equipments to ensure the quality reliability and consistency.
100% Cycle test: All battery packs are 100% cycle tested (Fully Discharged→Fully Charged→Fully Discharged→60% Charged) before package and all test reports are stored.
Unique tracking number: All battery packs are lasered an unique number on the case side for quality tracking.
Certifications:
| UL1642(Cell) | IEC62619 (Cell) | UN38.3(Cell/ Pack) |
