Trojan 6 Volt Replacements: Redway Power’s Lithium Packs for B2B Use
Redway Power’s lithium packs replace traditional Trojan 6V lead-acid batteries with lightweight LiFePO4 solutions offering 4x cycle life (4,000+ cycles), 50% weight reduction, and maintenance-free operation. Designed for B2B fleets (golf carts, airport vehicles), these 6V 220Ah modules feature integrated BMS for temperature/voltage protection and seamless drop-in compatibility with Trojan T-105 sizing. Pro Tip: Lithium’s flat discharge curve maintains 48V system voltage even at 20% SOC.

Why switch from Trojan FLA to lithium?
Lithium-ion batteries eliminate lead-acid limitations: charge times drop from 8+ hours to 2.5, energy density triples, and self-discharge rates fall below 3% monthly. For fleet operators, this reduces downtime and extends vehicle availability.
Lead-acid batteries lose 30% capacity when discharged beyond 50% SOC regularly, while LiFePO4 handles 80-100% DoD daily without degradation. Consider a golf cart fleet running 40 miles daily: Trojan FLA packs require replacement every 18 months, whereas Redway’s lithium units last 6+ years. Pro Tip: Use lithium’s 2C fast-charging capability during lunch breaks to extend operational uptime. Real-world example: A Florida resort saved $11,200/year replacing 48 Trojan banks with lithium, cutting energy costs by 60%.
How do Trojan 6V lithium replacements handle high loads?
Redway’s LiFePO4 cells deliver 1C continuous (220A) and 2C pulses (440A), outperforming Trojan FLA’s 75A max. This supports steep inclines and payloads up to 1,100 lbs without voltage sag.
Mechanically, the packs use 8mm aluminum enclosures with IP67 rating, compared to Trojan’s 4mm ABS plastic. Electrically, the BMS monitors each parallel cell group for balancing—critical when handling 300A+ controller draws. For example, airport baggage tugs using lithium maintain 45 km/h fully loaded, vs. 32 km/h with FLA. Pro Tip: Install pre-charge resistors on controller lines to prevent contactor welding during high-current startups.
| Parameter | Trojan T-105 | Redway LiFePO4 |
|---|---|---|
| Peak Current | 75A | 440A |
| Cycle Life @ 80% DoD | 1,200 | 4,500 |
| Weight | 29 kg | 13 kg |
What makes Redway’s packs drop-in compatible?
Terminal spacing (116mm) and footprint (197x179x330mm) mirror Trojan 6V standards, avoiding retrofitting costs. The packs include threaded M8 terminals and dual-voltage telematics (CAN/RS485) for fleet SOC monitoring.
Electrically, the lithium modules maintain similar voltage profiles under load—system controllers don’t require reprogramming. However, why do some users report initial compatibility issues? Often, it’s due to legacy chargers left connected; lithium-ready chargers with 7.3V/cell cutoff voltages are mandatory. For instance, Club Car precedent models transition seamlessly when using Redway’s CAN-enabled packs, automatically adjusting charge parameters via OEM handshake protocols.

FAQs
Yes, if original Trojan bank uses 6V series configurations (e.g., 48V = 8x6V). Confirm terminal spacing matches T-105/125 models before installation.
Do lithium replacements reduce vehicle weight significantly?
Absolutely—swapping eight Trojan 6V (232kg total) with lithium cuts weight to 104kg, increasing payload capacity by 128kg.
What’s the warranty on B2B lithium packs?
Redway offers 5-year full replacement warranties for commercial fleets, contingent on using approved chargers and maintaining <85% DOD cycles.
