There are plenty of options for a 3S LiPo battery for the Arrma Typhon Grom 223S BLX. After extensive comparison and testing of various 3S LiPos on the market, we’ve narrowed it down to three of the best replacement and upgrade options. These batteries not only significantly extend run time but also deliver more punch for bashing, reducing the need for frequent charging and maximizing your bashing enjoyment.
Tip: Typhon Grom battery tray size is appro. 110 x 40 mm (L x W)
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
My friend said, ‘The 3000mAh battery massively extends the run time for my Typhon Grom,’ and I couldn’t agree more. This battery has more capacity than two stock packs combined, meaning you’ll spend less time charging. When you take the backpack basher outdoors, you might only need this one battery.
Plus, the wattage output on this battery is noticeably higher than other lipos that claim a 30C rating, giving you sustained high punch without worrying about over discharge.
Best Budget Battery

HOOVO 2200mAh 3S 80C 11.1V Lipo with EC3 Connector
- Size: 75 x 33.8 x 26.4 mm
- Weight: 138g
What sets HOOVO apart from its competitors is the impressive balance it strikes between price and quality. One standout feature is its high C-rate, which truly surprised me. During actual runs, it gives the Typhon Grom a noticeable boost in acceleration. When I full pull the trigger, the 3S BL setup screams.
If you’re not a fan of big brands, give this one a serious look.
Best Performance Battery

Gens ace 2200mAh 3S 35C 11.1V Lipo with XT60 Connector
- Size: 75 x 34 x 25 mm
- Weight: 143g
Gens ace is a well-known name in LiPo batteries, and when it comes to quality, this brand doesn’t disappoint. From my years of experience, Gens ace LiPos stand out over competitors with better cell voltage gap, IR, and battery life. This translates to consistent discharge performance without the gradual decline over time.
What’s more, even under long, high-punch use, the voltage doesn’t suddenly drop but continues to deliver steady wattage.
One more thing I have to mention is that the new Gens ace batteries, including this one, now support automatic charging when paired with the Gens ace iMars Mini or D300 charger. Plus, they’re compatible with most RC LiPo chargers on the market—not limited like Spektrum batteries. I really appreciate this flexibility from Gens ace.
About Connector
Many people don’t realize that IC2 connectors aren’t compatible with EC2, and it’s a common mix-up to avoid. Finding an adapter for IC2 is also challenging, so you may need to swap out the connector to match your Typhon Grom. I recommend going with widely used options like EC3, XT60, or Deans connectors. These can handle high current, are more than sufficient for mini-scale vehicles, and are durable with excellent heat resistance.

November 20, 2024 at 12:04 amHello Vincent, I was very glad that I found your blog (I am a noooooob).
And although I couldn’t find your recommendations (within a reasonable price) in the Netherlands. I was happy with the guide.
I ended up buying some RC Plus Sigmas and now waiting for the Grom to arrive.
Regards,
Daryl.
