The following information is based on information posted at the RothMotors.com website. Specifications, schematics, and building instructions are here. Charging information is located on the charger wiki page.

Road vibration caused by the relatively small 5" solid polyurethane wheels can not only cause electronic components to disconnect and fail, it can cause the battery malfunction internally. The 1500X with the stock front suspension has a rough ride that is so hard on the batteries that Roth would not warranty batteries unless the customer also purchased a suspension upgrade kit.

This replacement battery comes with a 30 day Warranty (see note below) against Manufacturing Defects. If the battery is defective, we will only replace it with a new one—sorry no refunds. The warranty does not cover normal wear and tear or abuse. Please read this article for information on how to best care for your battery.

Note:The 1500X will only work with this lead-acid battery pack, the NiMH battery used in the 2000X is not compatible with the 1500X.

IMPORTANT The 1500X with the stock front suspension has a rough ride that is very hard on the batteries. We will ONLY warranty these batteries for the 30 days if you have also purchased the 2000X suspension upgrade kit.

IMPORTANT Replacing the 1500X battery involves working around delicate electronic components. It is possible that if you are careless you could damage the circuit board, permanently damaging your Motorboard. We can no longer get circuit boards for the 1500X, so extreme caution must be taken!!!

If you have an existing battery pack, and would like it refurbished, you can contact a local NiMH battery supplier, and they should be able to break apart your dead pack and install new NiMH cells into the pack. The cells are industry-standard D-size 1.2V NiMH cells. The stock pack had 8ah capacity cells, but you may install higher capacity cells and they will work as well. The battery charger that came with your 2000X Motorboard will also charge the refurbished pack.

If you are in Southern California, contact www.batterystore.com, they are familiar with Motorboard packs and have done refurbs before.

Custom Made Motorboard 2000X Battery (14Ah NiMH)

Custom 14Ah NiMH Double Power Battery sold on ebay by stefanrahovean
Replacement battery pack installed in scooter
Original version

stefanrahovean on ebay writes "As most of you know by now, I've been customizing batteries and Motorboards for quite some time. This year though, since the economy is in the gutter, I decided to give you the option to customize your own battery following my advice, saving you about $50 (my profit/battery sold). I have to warn you that if you don't have the confidence that you can do it, you're better of buying a battery from me. For $19.99 I will give you all the details necessary to put together your battery. All you need is a soldering tool, dc wires, some rubber and duct tape for isolation. I will also give you my supplier's website for you to buy the battery cells. This can take some work but it will save you $50. As for the battery itself, it will give you double the range and a small, but noticeable increase in speed."

"It comes with 14000mah which is twice as much the original battery offers. The voltage is the same (14.4 volts) therefore, you don't have to purchase a different charger. It is very easy to install and you'll be out riding in no-time. Please let me know if you have any other questions regarding this product. Once again, the battery costs $249 if you want to purchase it already customized by me. If on the other hand, you think you are capable to put together your own battery pack, I will give you all the insights for the price of $19.99 paid directly via PayPal"

This is a custom made battery which I designed for the 2000X Motorboard. It has five times the range of the original 2000X battery (13miles tested on a 160lb rider).Also the speed is increased with my battery because the F cell NiMH battery cell delivers a higher amperage discharge rate than the D cell used in the original battery. In addition, you would not need to purchase another charger since my battery is 100% compatible with your original charger. Simply replace the old battery with the new one and you're good to go. Another quality of this battery is the fact that I purchase the battery cells directly from a reputable manufacturer at the time of your purchase, therefore, eliminating the self discharge problem due to shelf time associated with this type of battery. The manufacturer has a 6 month warranty on these battery cells. This is my offer to all of those thousands of Motorboard passionates who bought the 2000X model and don't really enjoy the 2 mile range of their Motorboard. Please contact me for further info, suggestions or even complaints :) Ride with passion!!!!

More information on Custom Made Motorboard 2000X Battery

I had a green light + flashing red on the throttle. Turns out it was a faulty battery cell. I sourced some Cyclon batteries here in the uk which had to be modified as the shape of the top is now different. This was an easy mod with a dremel. The scooter is now working again.

I got them from Budget Barreries in the UK, at the time it was the lowest price I could find,

All that needed modifying was the shape of the plastic top and the two plastic strips down the sides. The original batteries were rounded to suit the shape of the bottom of the Motorboard, these batteries have an oblong shaped top and the plastic strips are a little longer.

This just needs to be cut to match the shape of the original batteries and can be done without damaging the actual battery itself as the plastic is outside the actual battery cell. It took me about 20 minutes to do the 4 batteries using a dremel and a small blade.

Tried it out yesterday and with both me and my 6 year old son on it we rode about 5 miles with a slight wind and the green light was still lit and power seemed fine. Maybe this will help anyone else out that just needs new batteries. These seem to last much longer than the later 2000x batteries.
