Best Sur Ron Battery Upgrade Options

We get a lot of comments that Sur Ron’s battery capacity isn’t enough for electric bikers to have a little fun. When we tried the Sur Ron X, we thought the same thing. If only there were better Sur Ron battery upgrades. Oh wait, there are. Let’s check them out.

Can I Upgrade My Sur Ron Battery?

Sur Ron’s battery design is a bit unique, and most aftermarket battery upgrades won’t work. But it’s not impossible to beef up your bike with an aftermarket Sur Ron battery upgrade. Later in this article, you’ll find out there are quite a few batteries you can use for your Sur Ron, or you can skip the jibber-jabber and find out how much is a Sur Ron battery.

Stock Sur Ron battery Specs

Here’s what the Sur Ron X’s stock battery looks like when you take it apart:

You can see the Sur Ron stock battery’s pretty simple, even if it looks a little high-tech. 176 Panasonic cells make up the battery, which can deliver 60V for a max of 90 amps. There’s also a pretty low capacity of 32ah and a max range of 50 miles. So this battery isn’t designed for long-range use. Instead, for quick bursts of power.

Stock Sur Ron batteries are approximately 14.5 inches high and 6.4 inches wide, so they fit perfectly inside the custom Sur Ron battery compartment. That’s also why most other battery upgrades aren’t compatible. They just aren’t the right size.

How Much Does A Sur Ron Battery Weigh?

Weight is around 20 lbs, so it’s still pretty light. Other dirt bike batteries tend to weigh around 30 – 40 lbs—which is a lot for the motor to handle.

This weight also includes the battery’s water-tight aluminum case, which keeps it from shorting out when it comes in contact with liquid.

To put it simply, here’s a table that shows the stock Sur Ron battery specs:

Cell brandPanasonic
Number of cells176
Power60V (90 amps max output)
Capacity32ah
Range50 miles
Dimensions14.5″ x 6.4″ x 5.5″
Weight20 lbs
Housing materialaluminum

It’s easy to tell the stock Sur Ron battery is minimalist. There are 176 Panasonic cells just strapped together to make a bigger battery, but it still packs some serious power. Amazing engineering.

To give you a better idea of what Sur Ron batteries are like, here’s a table:

ProsCons
Powerful enough for easy stuntsRange isn’t that great, so it’s not great for long distance riding
Easy to find a replacementStock replacements can be pricey (lowest we’ve found cost about $1599 USD)

I’d trade range for power if I could. Especially on stunt electric dirt bikes. I mean, who doesn’t love a 1/8 throttle twist power wheelie? Thanks to Sur Ron X, I don’t have to do much modding.

Sur Ron Battery Upgrade Options

Not satisfied with the Sur Ron range? We totally get it. Stock batteries can be a pain when it comes to how long we can ride. 

No worries, we’ve got you! Here are some of the best Sur Ron battery upgrades money can buy.

Sur Ron Battery UpgradeMain Feature
Sur Ron Battery 60v40ah capacity means more range 
Also heavier at 28 pounds
Sur Ron 72v Battery KitA higher voltage of 72V means more power output, paired with 45ah capacity for even better range 
Taller height of 18.5 inches, so you may have to modify your tank
Sur Ron Battery ExtenderThe 72V, 16Ah range extender gives you more range. 
You need an extra compartment or backpack to store the range extender

Not sure what to pick? I’d go with the Sur Ron 60v. You get the same power as the stock Sur Ron battery, plus a longer range, without having to modify anything. 

Sur Ron Battery 60v

It comes with the same voltage as the stock Sur Ron battery, but with a larger capacity of 40Ah. You get the same power output but more range. You can expect a range boost from 50 miles to around 70 miles.

The battery is the same size as the stock Sur Ron battery, so it fits right into Sur Ron’s battery compartment without any modification. Seeing as it weighs 28 lbs, acceleration may be a little sluggish, though. Also comes with a charger, so you don’t have to buy one separately. 

Cell brandChoice of Samsung, Panasonic, LG, Sanyo, or Sony
Number of cellsN/A
Power60V
Capacity40ah
Range~70 miles
Dimensions14.5″ x 6.4″ x 5.5″
Weight28 lbs
Housing materialAluminum

It’s nice to have a choice of battery cell brands. It’s always been Sony batteries for me because they last a lot longer and go through a lot more cycles.

Take a look at this list to see what the Sur Ron 60V battery has to offer:

Key Features

  • 1000 times battery cycle life
  • Charger inclusive on purchase
  • Same dimensions as stock Sur Ron battery

The fact that it’s just the same battery, albeit with a longer range, makes it the easiest one to put on your Sur Ron.

Check out this table for an overview of the Sur Ron 60V battery’s pros and cons:

ProsCons
Greater range for the same power output8 lbs extra weight may affect acceleration
Comes with its own charger so you won’t have to buy a separately

The extra charger is the best part. This means you won’t have to get a new charger or have your battery sockets modified.

You can get the battery at Alibaba for just $800.00 USD. It’s by far the cheapest option on this list.

Sur Ron 72v Battery Kit

Next up is a plus-size Sur Ron 72V battery upgrade from Lite Speed, specially designed for the Sur Ron X. 

The Sur Ron Lite Speed battery has a stronger voltage at 72V and a 45Ah capacity for improved power output and range. Expect 80 miles more of range and a slight increase in acceleration. 

There’s only one downside: It’s way too tall to fit in the Sur Ron battery compartment. There’s a chance you’ll have to remove the hatch entirely or modify the tank to keep the battery secure.

Check out this table for more information on the Sur Ron 72V battery kit:

Cell brandSony VT6
Number of cellsN/A
Power72V
Capacity45ah (3000mah)
Range~80 miles
Dimensions18.75” x 6.4″ x 5.5″
WeightN/A
Housing materialPolycarbonate

Although the Sur Ron 72V battery has a brittle polycarbonate housing, it still has pretty much the best power and range. I just wish they could’ve squeezed all that into a smaller package.

Check out this list to see what the Sur Ron 72V battery has to offer:

Key Features

  • 400A Bluetooth battery management system
  • Fast charging and regen up to 65A
  • Custom polycarbonate enclosure with rubber shrink finish and handle
  • Waterproof display with temperature and voltage readings
  • Fully programmable parameters 

I like the Bluetooth battery management system. You can optimize your bike’s performance on your phone. Fast charging is pretty awesome, too, since then you can just jump right back in after a few hours of chilling.

For a better idea of how the Sur Ron 72V battery kit works, here’s a table:

ProsCons
Greater power paired with longer range makes for a pretty good upgradeWay too tall for Sur Ron stock battery compartment

I don’t mind having more power on my bike, but I’d like to at least be able to close the battery hatch. Don’t wanna lose that power pack in the middle of a jump.

You can currently get the Sur Ron 72V battery kit from Lite Speed for $2,100.00 USD. It’s quite pricey but well worth it.

Sur Ron Battery Extender

This last one isn’t completely a battery replacer, rather it’s a piggyback Sur Ron range extender. Basically, it’s a second battery that you plug into your main battery to increase the amp hours or capacity and then extend range. That’s why it’s called a piggyback.

It’s made up of Molicel cells with a voltage of 72V and 16Ah of capacity that you add to whatever Sur Ron battery you’re using. This is a neat feature, but you’ll need an extra storage compartment or backpack to store it. You can expect a range boost of about 15 to 25%, depending on the main battery you use.

The Sur Ron range extender can also be used as a backup power reserve thanks to its on/off button.

Look at the table to see what’s in the Sur Ron battery extender.

Cell brandMolicel
Number of cellsN/A
Power72V
Capacity16ah
RangeMain battery dependent
Dimensions14.5″ x 6.4″ x 5.5″
WeightN/A
Housing materialRubber

Even though the battery extender is nearly perfect for long runs on mud flats, I hope that rubber housing won’t chafe in the water and heat.

The Sur Ron battery extender by LiteSpeed Bikes is made of what exactly? Let’s look at its key features:

Key Features

  • 300A bluetooth battery management system
  • 8awg silicone discharge bullets (compatible with stock Sur Ron plugs so no mods needed)
  • Piggyback extender (does not replace main battery but reinforces it)
  • Choice of 12ah or 16ah option

I like that piggyback feature. It’s good to have an extra battery that you can use right away without having to stop and pull it out.

To give you a better idea of what the Sur Ron battery extender is like, here’s a table:

ProsCons
Increases range by 15 – 25% depending on main battery usedIt won’t fit in the Sur Ron battery compartment, so you’ll need an extra bag/compartment to store it
Can be used as backup battery

I like the fact that it can be used as a backup battery. I’d love to have a little extra juice when my main battery dies.

Like the Sur Ron 72V battery kit, you can get the Sur Ron battery range extender from Lite Speed for a much cheaper $899.00 USD.

There’s a lot to consider when choosing the best battery upgrade for your Sur Ron, and there’s no one size fits all answer. Our suggestion? Choose one that best suits your riding style.
