The short answer: a 10 km one-way commute is a 20 km round trip per day. A pack of roughly 250-300 Wh (36V 7.5-10Ah) covers it with one charge a day; if you want two days between charges, hills on the route or a winter margin, step up to 500-700 Wh (48V 13-15Ah).
Matching battery size to a 10 km commute
Battery size is measured in watt-hours (V x Ah). What matters for a commuter is not the sticker range but the realistic figure - real riding delivers roughly 60-75% of the advertised number, as explained in why e-scooters rarely reach their claimed range. Here is how three SUNNIGOO commuters line up against a 20 km daily round trip, using the claimed figures from the product pages:
| Battery size | Example model | Claimed range | Realistic for 20 km/day |
|---|---|---|---|
| 36V 7.5Ah (270 Wh) | SUNNIGOO N5 350W ABE | 30-35 km | Covers it - one charge per day, thin margin |
| 48V 15Ah (720 Wh) | SUNNIGOO G7 500W ABE | 60 km | Covers it easily - about two days per charge |
| 48V 18Ah (864 Wh) | SUNNIGOO N8 650W ABE | 50 km | Covers it easily with headroom for hills |
The 270 Wh entry works, but with little slack: a hilly detour or a cold morning can push you close to empty. That is why the practical rule is: minimum 250-300 Wh for a 10 km one-way commute, comfortable from 500 Wh up. For the underlying arithmetic, see how to calculate real e-scooter range.
Three reasons to size up rather than size exactly
| Factor | What it does to your daily budget |
|---|---|
| Winter cold | Lithium packs deliver noticeably less usable capacity at low temperatures - budget roughly a third more consumption (x1.3) for winter riding, and check the winter service checklist. |
| Hills and stops | Climbing and accelerating from standstill draw far more current than cruising; a flat 20 km route and a hilly one are not the same battery load. |
| Battery ageing | After a few hundred cycles a pack holds less charge than when new (see how long an e-scooter battery lasts) - a bigger battery ages into the same commute instead of outgrowing it. |
One more reason not to oversize on paper: legal speed limits cap what speed - not distance - buys you. The country-by-country envelopes are summarised in e-scooter laws across Europe, and if you are comparing complete packages on a budget, the best e-scooter under EUR 1,000 shows how to weigh battery Wh against build quality.
Recommended SUNNIGOO models
Match the pack to your route - one charge a day or two:
- SUNNIGOO N5 350W ABE — 36V 7.5Ah, claimed 30-35 km, the lightest daily-commuter option
- SUNNIGOO G7 500W ABE — 48V 15Ah, claimed 60 km, two-day charging comfort
- SUNNIGOO N8 650W ABE — 48V 18Ah, claimed 50 km, headroom for hills and winter

FAQs
1. How many watt-hours do I need for a 20 km round trip?
At a typical commuter consumption, 20 km needs roughly 200-250 Wh of real energy use, so a 250-300 Wh pack is the workable minimum and 500-700 Wh gives you the margin that hills, headwind and cold quietly consume.
2. Does cold weather change the battery size I need?
It changes how far a given pack goes. In low temperatures lithium batteries deliver noticeably less usable capacity, so budget roughly a third more consumption in winter - a pack that comfortably covers your route in summer may only just manage it on a cold morning.
3. Is a bigger battery heavier - does it matter for commuting?
Somewhat. A 720 Wh pack weighs a few kilograms more than a 270 Wh one, which matters most when carrying the scooter upstairs or onto public transport.That weight penalty also explains why riders on longer routes start weighing a different vehicle altogether - the trade-offs are laid out in e-scooter vs e-bike for a 15 km commute. If you fold and carry daily, the smallest pack that covers your realistic route with margin is the right choice.
4. Can I charge every day, or does that wear the battery out?
Daily charging is normal and fine for lithium packs. What shortens life is habitually storing the battery at 0% or 100% for long periods and charging in freezing conditions - ride, charge, and store around half charge when the scooter sits for weeks.
