There are two categories of vehicles in the market. Low speed and high speed. The subsidy is offered by Central Gov only on High speed vehicles, which comply with CMVR rules and registered with RTO. Low speed vehicles are exempted from RTO registration and there is no subsidy on it by the Gov. Our’s are low speed vehicles therefore no subsidy from the Gov.
Allow partial discharges and avoid full discharge (usually).
Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles. There is one exception. Battery experts suggest that after 10 to 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.
Now our batteries come with a mobile app, which will show you accurate SOC(state of charge) in Ah and %.
If a lithium-ion battery is discharged below 2.5 volts, a safety circuit built into the battery is activated and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery. Also, for safety reasons, do not recharge deeply-discharged Dexpress battery if they have been stored in that condition for several days. In case if it doesn't start charging after few hours please send an email on firstname.lastname@example.org with a screenshot of the app for our engineer to identify the issue and provide you with a solution as quickly as possible.
Store your battery at room temperature preferably between 20 °C to 25 °C. The worst thing that can happen to a lithium-ion battery is to have a full charge or full discharge and be subjected to elevated temperatures. Oxidation of lithium-ion is at its highest rate in such condition. Storing lithium-ion batteries at 40-60 % SOC in a cool and dry room is recommanded.
Think about getting a high-capacity lithium-ion battery, rather than carrying a spare. Batteries deteriorate over time, whether they're being used or not. So a spare battery won't last much longer than the one in use. Larger capacity battery will remove range anxiety and last longer if charged in between 20 to 80% SOC.
One of the biggest things that reduces the life of a battery is temperature. A battery loses charge capacity when temperatures are extreme. As temperatures increase, especially over 100 °F (38 °C), so does internal discharge of your batteries. If a new fully charged battery is left sitting 24 hours a day at 43°C for a month, it would most likely not start at all. Cold weather isn’t nearly as hard on batteries as hot weather. Still, cold weather can also be very hard on a battery.
- Always charge your battery directly after each use. One of the most damaging things you can do to any battery is leave it in a discharged condition. It is recommended that you recharge your battery within a maximum of 24 hours after its last use.
- Your battery should be stored and recharged in a dry environment between 0 °C to 35 °C. It can be used in temperatures of -10 °C to +45 °C but any long term storage at extreme temperatures i.e. car boot at the height of summer, should be avoided.
- To clean your battery. just use a damp cloth. Do not use any solvents or abrasive cleaners.
- Do not short the terminals or open the casing. There are no serviceable parts inside and to do so would invalidate your warranty.
- Do not drop, throw or puncture the battery.
- Do not disassemble the battery.
- Do not use or store in extreme temperatures.
- Do not charge through the discharge outlet. Unless they are same port
- Do not solder anything directly to the terminals.
- Do not charge with any other charger other than Dexpress charger.
- Do not immerse in water or other liquid
- Do not short the battery terminals.
We warranty Battery capacity not the range. Our new batteries have mobile app, which shows the battery capacity and drop in charge in % and Ah as you ride the vehicle. Range depends on many factors as follows;
- Traffic conditions have the worst impact on the range. The range may reduce at least 20 to 30% of the maximum range, in heavy traffic condition compared to empty road.
- Double seat can reduce the range by 20% over only rider weighing less than 70kg.
- Rider's riding behaviour‐Frequent and sudden braking, rash driving will reduce range substentially.
- Road conditions‐Uneven and rough will have more road resistance and reduce range.
- Wind conditions‐Head wind will reduce the range.

Lead acid batteries are comparatively cheap to bring down the initial cost of the vehicle, but there are following drawbacks;
- Lead acid have the shortest cycle life. It can't last more than a year. There is a recurring cost every year which is almost equivalent to cost of new battery.
- Lead acid is very heavy therefore difficult to carry for charging purpose.
- Lead acid is bad for the environment due to lead content.
Lithium Iron Phosphate(LFP) batteries can last 5 to 10 years depending on the use as described in the battery maintenance section. Weight of the Lithium batteries makes it portable (especially in 2-wheeler) due to its weight which is ½ to ⅓ of Lead acid. In the long run they are definitely very cost effective.
Life of the battery
It has a life cycle of 1500 to 2000 or more depending on use. With normal use and once a day charge it can last up to 5 years. This is one of the longest lasting battery type commercially available.
It doesn't catch fire or blast unlike Lithium Ion (NMC). This is one of the safest lithium chemistry.
It weighs around 12 to 18 kg depending on the size, which is portable for those living in apartments with elevators. It comes with a battery case, which has handle to carry comfortably.
DeXpress comes with the battery capacity ranging from 1.4 to 2.5 KW. The range of 70 to 160 Km can be achived depending on traffic, load and riding conditions. The fuel cost estimates to 2.75 Rs/Km. considering the average consumption of 1 litre fossil fuel for 35 to 40 km. Following savings are calculated on these basis;
70 Km / day 200 Rs/Day 73,000 in a year 6 days a week will save 62,000/year
50 Km /day 140 Rs/Day 51,000 in a year 6 days a week will save 43,000/year
30 Km /day 90 Rs/Day 32,000 in a year 6 days a week will save 28,000/year
The vehicle cost can be recovered in 1 to 2 Years. The vehicle is designed for delivery of goods by the shops and restaurants. They use much more than the average per day.
The above calculations are just an indications and not a claim for Dexpress vehicle and/or battery. These calculations may vary substentially depending on various variable factors.
DeXpress doesn’t have engine, gearbox, spark plug etc. which are prone to mechanical wear and tear and require maintenance. Our scooter has BLDC (Brushless DC) Motor. These motors run by change in magnetic field and hence there is no friction. There is no mechanical wear and tear. Apart from this, all other parts are electronic which controls the speed, brake lights etc.
Therefore it doesn’t need any service like oil change, spark plug change etc. It is maintenance free. Whatever little maintenance needs to be done is self-maintenance.
This vehicle is designed for delivery or shopping within the city limits and mostly within 5 to 10 km radius, though it can be used for long distance as well. Therefore, the max speed is limited to 25 Km/hr. It reduces the chance and severity of an accident.
The body is designed with least use (negligible) of plastic. The tubular High Carbon Steel body doesn’t get damaged with minor collisions and also acts like a protective gear to the rider.
The vehicle is certified by ARAI and ICAT under max speed 25 km/hr category; it doesn’t fall under motor vehicle act and therefore doesn’t need any license, RTO registration or mandatory insurance. We recommend third party insurance or full insurance as per the customer choice. We don’t include insurance in the price.
The warranty is strictly against any manufacturing defect. It excludes any damage due to electrical fluctuation, accidents, and natural calamity. The warranty doesn't include anything that can't be manufacturing defect. Please see Warranty page for more details
