The Bright Way Group BW EVGC8 is an 8-volt, 170Ah deep-cycle battery designed primarily for golf carts and applications requiring sustained power delivery. As a sealed lead-acid (SLA) battery, it utilizes AGM (absorbent glass mat) technology to deliver reliable performance in deep discharge-recharge cycles. Its nominal 8V output allows integration into 48V systems when six units are connected in series, aligning with golf cart power configurations. The 170Ah capacity supports extended runtime for electric vehicles and stationary equipment, emphasizing durability under repetitive energy demands.

What technical specs define the BW EVGC8 battery?
This 8V 170Ah battery operates within 1.210–1.280 specific gravity ranges for electrolyte optimization. Designed for 500+ cycles at 80% depth of discharge (DoD), it withstands vibrations up to 6G. Pro Tip: Maintain charge between 50–80% when idle to prevent sulfation in lead-acid chemistry. For example, a 48V golf cart system using six BW EVGC8s provides 8.16kWh total energy—sufficient for 18–25 miles per charge on hilly terrain.
How does it compare to lithium alternatives?
Unlike lithium-ion batteries, the BW EVGC8 sacrifices weight efficiency (35–40 kg vs. 15 kg for LiFePO4) for lower upfront costs. Its 70–75% energy efficiency contrasts with lithium’s 95%, but requires no battery management system (BMS). Pro Tip: Lead-acid remains cost-effective for infrequent users, while lithium suits daily operators needing faster charging.
| Parameter | BW EVGC8 (Lead-Acid) | LiFePO4 8V |
|---|---|---|
| Cycle Life | 500 cycles | 2000+ cycles |
| Weight | 38 kg | 12 kg |
| Peak Efficiency | 75% | 98% |
What maintenance does it require?
Monthly electrolyte level checks and terminal cleaning are mandatory. Equalization charging every 30–60 days prevents cell stratification. Warning: Overwatering dilutes acid concentration—refill only with distilled water after full charging. For example, terminals left uncleaned may develop 0.5–1V voltage drops, reducing runtime by 15–20%.

FAQs
Yes, but ensure charge controllers compensate for lead-acid’s lower absorption voltage (14.4–14.8V vs. 14.6V lithium). Avoid exceeding 25% DoD daily to extend lifespan.
What’s the recharge time for this battery?
8–10 hours with 17A chargers. Fast-charging above 0.2C (34A) accelerates plate corrosion—always follow manufacturer’s CC/CV profile.
