Our Arrma Mojave Grom 223S BLX need a high-capacity 3S LiPo! If you’re in the same boat, you’re in the right place.
After extensive market research, comparisons, and reviews, I’ve narrowed it down to the top three replacement 3S LiPo batteries. They not only extend runtime but also boost punch-out performance, making bashing even more fun.
Tips:
1. These batteries come with EC3/IC3 connectors, you’ll need an adapter or change the connector.
2. The Mojave Grom battery tray is approx. 130 x 38mm (L x W).
Read on to quickly make the best choice!
Best Long Run Time Battery
Powerhobby 3000mAh 3S 30C 11.1V Lipo with EC3 Connector
- Size: 104 x 34 x 25.5 mm
- Weight: 179g
Capacity: This is probably the highest capacity 3S Lipo with EC3 you can find for the Mojave Grom. At 3000mAh, it significantly extends run time, more than doubling the stock battery. With two of these, you’ll have enough power for a full day of bashing fun.
C-rate: Although its rated 30C discharge rate is slightly lower than other similar-sized batteries, the actual punch it delivers is on par. In my experience, it lasted through long periods of hard bashing.
Discharge Consistency: This battery shows minimal voltage drop during high-throttle runs, so you won’t feel any power loss when you pull the trigger hard. This is proof of its small cell voltage gap, and its quality really puts it ahead of the competition.
Best Budget Battery
HOOVO 2200mAh 3s 50C 11.1V Lipo with EC3 Connector
- Size: 104 x 34.5 x 24.5 mm
- Weight: 174g
This battery can be considered the best overall option. If you’re looking for lipos for mini-scale vehicles, it’s a good choice. From what I know, these batteries are widely compatible, working with the Arrma Grom series, Losi NASCAR, Traxxas Mini Maxx, MJX, Rlaarlo, and more.
Some might think budget batteries lack quality, but as long as you use this one correctly, it can handle over 200 cycles, giving it a battery life of up to 3 years, YMMV. You’ll never experience issues like a cell dropping to 0V, overheating, or swelling.
BTW, this battery provides enough wattage for the Mojave Grom 3S BL Power System, delivering a stable current for higher punch and reliable speed runs.
Best Performance Battery
Gens ace 2200mAh 3S 35C 11.1V Lipo with XT60 Connector
- Size: 75 x 34 x 25 mm
- Weight: 143g
For RC LiPo battery users, Gens ace is one of the most reliable options. Based on comparison results, Gens ace batteries outperform competitors in both cell voltage gap and internal resistance, allowing Mojave Grom models to achieve extended speed runs and handle high ramp sends effortlessly.
Additionally, when paired with Gens ace smart chargers like the iMars Mini and D300, these batteries offer automatic charging capabilities at a reasonable price. Unlike Spektrum closed-source technologies, Gens ace lipos compatible with most popular chargers on the market.
