Batteries cause more "it arrived broken" emails than any other part of a small RC car, and almost none of those are actually broken. Ten minutes here will save you a support thread.

Four habits that do most of the work

1. Disconnect the battery from the ESC when the car is not in use. Leaving it plugged in is the single most common way to kill a pack slowly.
2. Use the supplied or manufacturer-recommended charger. Our micro cars charge over USB or USB-C; FPV packs need a proper balance charger. Do not improvise.
3. Let a cold pack warm up first. If your parcel arrives in cold weather, allow the battery to reach room temperature for at least two hours before charging.
4. Do not charge unattended, and do not store a pack flat. A partially charged battery stored somewhere dry and cool lasts longer than a full one left in a hot car.

What "runtime" really means

Our 1/43 cars list anything from 20–25 minutes (WHOOSH H4, 240mAh) to 30–35 minutes (Hstar D43-06S / 06Q, 300mAh) and about 30 minutes (JXC SP4301-GR, 380mAh). Those are best-case figures on a smooth floor with sensible throttle. Carpet, cold, full throttle and repeated full-lock slides all shorten them. Charge times vary even more: 50–60 minutes on the Hstars, about 180 minutes on the Supra. If long sessions matter, a spare battery is a better purchase than a faster car.

Why battery orders sometimes take longer

Lithium batteries need specialised carrier handling and compliant air routes. We dispatch within 1–5 business days, then tracked economy shipping takes roughly 7–18 business days depending on destination, or 5–10 by express. Battery-containing orders may need an extra 2–4 days for customs and safety scans.

Standalone LiPo packs are also restricted in some countries without a vehicle in the same shipment. If your destination is affected, we will contact you before dispatch to bundle the battery with a vehicle or adjust the order. For express DHL, UPS or FedEx shipments, the carrier may add a clearance handling fee.

Three quick answers

• Can I order a spare battery on its own? Sometimes. If your destination restricts standalone packs, we will tell you before dispatch.
• Is the car battery included? Yes on every RTR car we sell. The transmitter's AA batteries are the usual exception — check the product page.
• The car will not hold a charge. Email hello@gomnirc.com with your order number and a short video within 30 days. We will replace the part, the model, or refund it. No repair queue.
