Redway Power: Custom Lithium Battery Packs for Golf Carts and Utility Vehicles

Redway Power specializes in custom lithium battery packs tailored for golf carts and utility vehicles. Their LiFePO4-based systems prioritize safety, longevity (3,000–5,000 cycles), and rapid charging (1–2 hours), with modular designs supporting 72V–144V configurations. Pro Tip: Opt for NMC cells if energy density (200–300 Wh/kg) is critical for extended off-grid use. Understanding Lithium Golf Cart Batteries – A Comprehensive Guide

What are the key benefits of custom lithium battery packs?

Custom packs outperform lead-acid batteries with higher energy density, faster charging, and longer lifespan. LiFePO4 cells operate efficiently in -20°C to 60°C ranges, ideal for year-round utility vehicle use.

Redway’s batteries achieve 95% depth of discharge (DoD) versus 50% in lead-acid, effectively doubling usable capacity. Take a 48V 100Ah system: LiFePO4 delivers 4.8kWh actual energy vs 2.4kWh from similar lead-acid. But how does this translate practically? Golf carts gain 25–35% more range per charge, while maintenance costs drop by 70% due to no water refills. A proprietary battery management system (BMS) monitors cell voltages ±10mV, preventing over-discharge below 2.5V/cell.

Table 1 compares lithium and lead-acid performance:

For example, a Texas golf course reduced battery swap frequency from weekly to biannually after upgrading to Redway’s 72V packs. Pro Tip: Use low-temperature charging circuits if operating below 0°C to prevent lithium plating.

How are custom battery packs designed for specific vehicles?

Design starts with analyzing voltage requirements, peak current draw, and physical dimensions. Redway engineers match cell chemistry (LiFePO4/NMC) to duty cycles—frequent deep discharges favor LiFePO4’s flat voltage curves.

Take a Club Car DS upgrade: Original 48V lead-acid measures 33x19x11 inches. Redway’s lithium replacement uses prismatic cells in 30x16x9 inches, saving 40% space for added storage. Controllers need reprogramming since lithium maintains voltage above 50V until 90% discharged, unlike lead-acid’s linear drop. Why does this matter? Motors draw higher currents as voltage sags, causing premature shutdowns. Custom packs compensate with hybrid topologies—parallel cell groups for current (e.g., 4P16S for 600A peaks) and series for voltage. Table 2 shows design variables:

Pro Tip: Request vibration testing reports—poorly welded cells fail within 6 months on rough terrain.

Can lithium batteries integrate with existing charging systems?

Most lead-acid chargers lack lithium-specific CC-CV algorithms and voltage cutoff. Redway provides compatible 10A–30A chargers with CAN bus communication to optimize cycle life.

Standard golf cart chargers apply 59V (lead-acid) to 48V lithium packs, which fully charge at 54.6V. Using them risks undercharging by 10–15%, gradually causing sulfation in lithium cells. However, some modern chargers like Lester Summit II have selectable profiles. Always verify termination voltage—LiFePO4 requires 3.65V/cell (±0.05V). For a 16S pack, that’s 58.4V total. What happens if you ignore this? Continuous trickle charging above 58.4V accelerates electrolyte breakdown, losing 5% capacity monthly. Redway’s chargers include temperature-compensated voltage adjustments, critical for outdoor fleets. Pro Tip: Install a voltage logger for 48 hours post-upgrade to catch compatibility issues.
