Batteries
The longest-lasting RC car batteries
Two ways to read that: the pack that runs longest per charge, and the pack that survives the most charges. They are not the same battery.

For the longest run time, buy the highest capacity (mAh) pack that physically fits your car's battery tray. For the longest service life, buy a reputable brand and store it at half charge. Our pick on both counts is Gens Ace — but two Zeee packs for the same money will give you more total driving today.

Best balance of price and quality

The sensible middle: better built than the bargain packs, cheaper than the premium ones.
The two questions, separated
| You want... | Buy | Because |
|---|---|---|
| The longest single session | The highest-capacity pack that fits | Run time scales almost directly with mAh in the same car |
| The most total driving today | Two mid-priced packs | Two adequate batteries beat one excellent one every single afternoon |
| The pack that survives longest | A reputable brand, stored properly | Cell consistency is what separates a three-year pack from a one-year one |
| Zero setup hassle | A Traxxas iD pack with a Traxxas charger | The charger configures itself from the battery — nothing to get wrong |

#1 · The reliable default
Gens Ace 2S LiPo battery
The brand most people settle on once they have been burned by a cheap pack that puffed after a month.
8.7/10our score for this use
LiPo is the standard rechargeable battery chemistry for RC cars: lighter than the older NiMH type and it holds its power right up to the end of the run rather than gradually fading. 2S means two cells — the size most 1/10 cars take.
What it does well
- Consistent pack-to-pack quality, which is the whole argument for paying more for a battery
- Holds voltage under load, so the car feels the same on lap ten as on lap one
- Sold in all the common connector types and sizes
What it does badly
- Costs more than the budget brands for capacity you can measure but may not notice
- Like all LiPo packs it must be stored at partial charge, not full, or it degrades
- Needs a balance charger — it cannot be charged with the wall plug from a toy car

#2 · Traxxas owners
HOOVO 2S LiPo with a Traxxas-style plug
The straightforward LiPo upgrade for a Traxxas, in a hard case and two to a box.
8.3/10our score for this use
A pair of 7.4 volt 6200mAh 70C hard-case LiPo packs wired with the Traxxas-style plug, so they drop into a Traxxas tray and connect to a Traxxas car without an adapter. HOOVO lists them at 139 x 47 x 25mm and 290 grams each, sized for 1/10 and 1/8 vehicles. Two packs is the difference between half an hour of driving and an afternoon of it.
What it does well
- Fits Traxxas battery trays and connects to a Traxxas car with no adapter
- Two 6200mAh packs in one box, for roughly what one branded pack costs
- Hard case, so a crash does not deform the cells
What it does badly
- HOOVO says the plug is the older style and may not mate with a Traxxas charger — these need a standard LiPo balance charger
- No iD chip, so the charger has to be set by hand
- Same LiPo storage rules apply — it still needs care

#3 · Middle ground
Ovonic 2S LiPo battery
The sensible middle: better built than the bargain packs, cheaper than the premium ones.
8.4/10our score for this use
A mid-priced LiPo brand that has built a reputation for reliability without the premium price. For a car that gets used on weekends rather than raced, this is the tier that makes sense.
What it does well
- Noticeably better built than the cheapest packs on the shelf
- Widely available in the common sizes and connectors
- Good value if you want two packs instead of one premium pack
What it does badly
- Not the last word in performance if the car is being raced
- Quality is consistent but not at the level of the top-tier brands
- Still requires a proper balance charger

#4 · Two packs, low spend
Zeee 2S LiPo battery
Sold in twos for about what one premium pack costs — the reason so many garages have a stack of them.
8.1/10our score for this use
The budget end of the LiPo market, usually sold as a two-pack. For a gift where the goal is more driving time rather than maximum performance, two adequate batteries beat one excellent one.
What it does well
- Two-packs at a price that makes a spare battery an easy decision
- Perfectly adequate for bashing, which is what most of these cars do
- Widely stocked in the common sizes
What it does badly
- Pack-to-pack consistency is not at the level of the premium brands
- They tend to age faster if they are stored fully charged — which beginners do
- Not the choice for racing

#5 · Families new to this
Traxxas Power Cell NiMH battery
Slower and heavier than LiPo, and far more forgiving of the mistakes a first-time owner makes.
8.3/10our score for this use
NiMH is the older rechargeable chemistry. It gives less punch and less run time than LiPo, but it tolerates being left on a shelf half-charged, being fully drained, and being charged on a simple charger — all things that shorten a LiPo's life.
What it does well
- Far more tolerant of neglect than LiPo, which suits a household new to the hobby
- Can be charged with the simple charger that comes with many Traxxas cars
- Works with Traxxas' iD system, which sets the charger up automatically
What it does badly
- Heavier and slower than a LiPo of the same capacity — the car feels duller
- Shorter run time for the same size pack
- Most people replace it with a LiPo within a few months anyway
Specifications from Traxxas' batteries and chargers range.

Capacity is limited by the battery tray, not your budget
It is tempting to buy the biggest pack listed, but a LiPo's physical size grows with capacity and the battery tray on the car does not. Measure the tray — or check the manufacturer's stated maximum pack size — before ordering. A pack that does not fit is a pack that goes back.
How we picked
On published capacity and on each brand's reputation for cell consistency, which is what decides service life. We do not cycle-test batteries and do not claim to — see our methodology page.
