Customer Reviews
No false capacity marking. Long and real battery range. Mileage after full charge matches description, very satisfied!
Easy to install and remove. Plenty of power, real range matches description. Well-made and good waterproof performance, ideal for daily commute.
The declared power did not match, I asked for a partial refund to keep the goods, but they wanted to return 3.50 out of 180 euros, so I returned the goods.
The actual endurance is close to the seller’s introduction, fully competent for daily commuting and short trips. Matched charger works quietly without heating during charging. The waterproof outer casing prevents short circuit caused by rainwater infiltration. The battery maintains stable performance after multiple charge-discharge cycles with reliable quality.
Fast delivery with solid protective packaging and complete accessories. I finished installation within ten minutes by myself. It outputs smooth power during riding, with stable acceleration and steady power under full load. No bulging or liquid leakage of the battery. The seller provides thoughtful after-sales guidance and clear warranty policy, bringing great usage assurance. Suitable for people who need a replacement e-bike battery.
