Best RC Battery Chargers UK 2026 — LiPo Balance Chargers Compared

Four RC battery chargers: Etronix PowerPal Mini, PowerPal 3.0, PowerPal Compact X4 and Gens Ace iMars D300

The best RC charger for most people is the Etronix PowerPal Mini AC: a 60W mains balance charger with storage mode for about £37. On a budget, the G.T Power SD4 III Pro does 2S to 4S for under £30, and if you charge several packs at once, the PowerPal Compact X4 has four independent outputs.

The USB chargers that come with many ready-to-run cars work, but they are slow and tell you nothing. Any charger below is a real upgrade. They are ordered by price; for the method, see how to charge LiPo batteries safely.

What to look for in a charger

Balance charging. Essential for LiPo. Every charger here balances the cells as it charges.

Cell count. Make sure it covers your biggest pack. 2S to 4S suits most cars; 6S needs a charger like the Ultra-X 80.

Power. Watts decide how fast big packs charge. 50 to 60W suits most car packs; 100W and up for large 4S and 6S.

Mains or DC. Built-in power supplies are simplest at home. AC/DC chargers can also run from a 12V supply at the track.

Frequently asked questions

What charger do I need for an RC LiPo battery?
A balance charger with a LiPo program that covers your pack’s cell count. For most 2S and 3S car packs, a 50W to 60W charger like the Etronix PowerPal Mini is ideal.
Can I use the charger that came with my RC car?
Usually, yes, but supplied USB chargers are slow and have no storage mode. A proper balance charger charges faster and looks after the pack better.
How many watts does an RC charger need?
Enough for the current you want at your pack’s voltage. As a guide, 50W charges a 2S pack at about 6A or a 3S pack at about 4A.
Do I need a LiPo bag when charging?
Yes. Always charge on a hard, non-flammable surface in a LiPo safety bag and stay with it. Our guide to how to charge LiPo batteries safely covers the rest.
