What Batteries And Chargers Are Included In V-Force Series?
The V-Force Series includes 72V and 60V lithium-ion battery packs (LiFePO4 or NMC) paired with smart chargers featuring CC-CV protocols. Batteries range from 30Ah to 200Ah, optimized for e-scooters, golf carts, and industrial EVs. Standard chargers deliver 10–20A output with adaptive cooling and BMS communication to prevent overcharging. For instance, the 72V 100Ah LiFePO4 bundle supports 200+ km per charge. 72V Lithium Battery Solutions
What battery configurations are available in the V-Force series?
V-Force offers 72V and 60V lithium batteries with capacities spanning 30Ah–200Ah. LiFePO4 variants prioritize cycle life (3,000+ cycles), while NMC packs focus on compact energy density (180Wh/kg). Modular designs allow series/parallel expansion up to 600Ah.
Battery configurations include single-unit 72V 100Ah packs for mid-range EVs and stacked 60V 200Ah systems for heavy-duty applications. Pro Tip: Use factory-supplied busbars for expansions—DIY connections risk resistance mismatches. The 72V 30Ah NMC battery, for example, weighs just 12kg, ideal for portable e-scooters.
Battery Type | Voltage | Use Case |
---|---|---|
LiFePO4 | 72V | Golf carts |
NMC | 60V | E-scooters |
LiFePO4 | 60V | Forklifts |
Beyond capacity, note that 72V systems deliver 20% higher torque than 60V equivalents. But why does this matter? For uphill climbs or heavy payloads, the extra voltage prevents motor stalling. Charging these typically requires 84V (LiFePO4) or 90V (NMC) cutoffs.
Which chargers are compatible with V-Force batteries?
V-Force includes smart chargers with CANbus or RS485 BMS communication. 72V models output 15A (default), adjustable to 20A for rapid charging. LiFePO4 chargers terminate at 3.65V/cell (87.6V total), while NMC units reach 4.2V/cell (88.2V).
Chargers feature IP54 waterproofing and temperature-compensated algorithms. For instance, a 72V 100Ah pack charges from 20% to 90% in 4 hours at 20A. Pro Tip: Avoid 3rd-party chargers lacking BMS handshake protocols—they’ll only bulk charge to 80% capacity. Practically speaking, using a 60V charger on a 72V battery risks undercharging by 15V, reducing runtime by 40%.
How does the BMS enhance V-Series safety?
The integrated 16S BMS monitors cell voltages (±0.02V accuracy), temperatures, and current. It disconnects loads at ≤58V (60V systems) or ≤68V (72V) to prevent deep discharge. Active balancing redistributes 200mA during charging, minimizing cell drift.
In real-world terms, if one cell in a 72V pack weakens, the BMS throttles discharge rates to maintain stability. Why is this crucial? Unbalanced cells can reduce total capacity by 30% within 50 cycles. Additionally, the BMS logs error codes (e.g., “Err03” for overtemperature) accessible via Bluetooth apps. 60V 100Ah LiFePO4 Battery – Smart BMS
What’s the lifespan of V-Force batteries?
V-Force LiFePO4 batteries retain 80% capacity after 3,000 cycles (10+ years at daily use), while NMC variants last 1,500 cycles. Depth of discharge (DoD) matters: cycling at 100% DoD halves lifespan compared to 80%.
For example, a 72V 200Ah LiFePO4 pack used in a golf cart with 70% daily DoD will last ~12 years. Charging habits also matter: consistently stopping at 90% instead of 100% adds 500+ cycles. Pro Tip: Store batteries at 50% charge if idle for >1 month—full charge accelerates electrolyte degradation.
Factor | LiFePO4 | NMC |
---|---|---|
Cycle Life | 3,000 | 1,500 |
Energy Density | 140Wh/kg | 180Wh/kg |
Cost/Ah | $1.80 | $1.50 |
Can V-Force batteries replace lead-acid systems?
Yes, V-Force lithium batteries are direct replacements for lead-acid in 60V/72V setups. They provide 2x the usable capacity at half the weight—e.g., a 72V 100Ah LiFePO4 (64kg) replaces a 150Ah lead-acid (210kg).
Retrofitting requires verifying terminal polarities and controller voltage limits. Some lead-acid chargers lack lithium profiles, risking overcharge. For instance, a legacy 72V lead-acid charger might apply 88V indefinitely, whereas lithium needs automatic cutoff at 84V. Pro Tip: Enable the BMS’s lead-acid compatibility mode to handle float charging if mixed systems are unavoidable. Practically speaking, upgrading cuts charging times from 8+ hours to 3–4 hours.

FAQs
No—proprietary BMS protocols ensure compatibility only with V-Force packs. Third-party batteries risk communication failures and incomplete charges.
Can I charge a 72V V-Force battery with a 60V charger?
Never—the 12V deficit causes severe undercharging, reducing capacity by 70% and triggering BMS undervoltage lockouts.
How to troubleshoot a V-Force charger showing ‘ERR 05’?
‘ERR 05’ indicates a faulty temperature sensor. Power cycle the system and inspect battery terminals for debris. If persistent, contact Redway support.
