A battery is only as good as its installation. ChamRider accessories — chargers, battery cases, cables, and controllers — are spec’d for actual operating currents, not theoretical minimums. No melted connectors, no charger cutoffs mid-session, and no compatibility guesswork between pack and drivetrain.
Frequently Asked Questions
What accessories does Chamrider offer for e-bikes?
Chamrider offers fast chargers, connection cables, LCD displays, safety contactors, and mounting kits compatible with the battery range for simplified installation.
Are Chamrider chargers fast?
Chamrider chargers offer power from 2A to 5A depending on the model. A 5A charger charges a 48V 15Ah battery in about 3 hours, versus 7.5 hours for a standard 2A charger.
Are Chamrider LCD displays compatible with all motors?
Chamrider LCD displays use the standard UART protocol. They are compatible with most 250W-750W brushless motors equipped with a standard controller.
Does Chamrider offer frame mounting kits?
Yes, Chamrider provides mounting brackets adaptable to frame tubes of 35 to 80 mm diameter, with stainless steel clamping for secure attachment without frame drilling.

Chamrider Charger
The charger is the accessory most often overlooked when assembling an e-bike kit, yet it directly determines how long your cells will last. A charger that pushes individual cells beyond 4.2 V in CC/CV mode causes irreversible lithium plating and capacity loss from the first charge cycle. ChamRider chargers are voltage-matched to 36 V, 48 V, and 52 V packs with selectable charge current — 2 A for maximum longevity, 5 A for faster top-up — and a cutoff precision of ±0.5 %, sharp enough to avoid the top-of-charge stress that degrades cells fastest.
A BMS-connected control display turns range guessing into data-driven riding. With a Bafang-compatible display (DP-C18, SW-102, or DPC-14) connected via UART, you read current voltage, remaining watt-hours, speed, and assist level in real time. For daily commuters, knowing that 180 Wh remain at the halfway point — not just a vague three-bar indicator — changes how you manage assist selection and effort over the route. Many Bafang displays also allow field reprogramming of assist ratios and speed limits to adapt the bike to specific routes.
Cables and connectors are the most common failure point in hand-assembled e-bike kits. An improperly crimped XT60 or undersized battery cable carrying 25–30 A peak on a 750 W system generates resistive heat at the junction, eventually creating intermittent contact that triggers BMS cutoff at the worst possible moment. ChamRider supplies packs with XT60 or Anderson SB50 connectors depending on rated power, minimum 12 AWG wire cross-section, and heat-shrink over every solder joint — details that matter on a 60 km ride with no backup.
Made from sturdy materials, ChamRider cases are lightweight yet resistant to shocks and weather conditions. This ensures the durability of your installation. Each case is designed to accommodate different cell configurations, offering maximum flexibility to suit your specific needs. Whether you want to increase the range of your electric bike or simply replace a damaged case, ChamRider battery cases meet the highest standards.
ChamRider takes pride in supporting its customers in their projects. ChamRider provides guides and helpful resources to facilitate assembly and repair. This makes the process accessible even to beginners. Thanks to smart design, ChamRider cases allow adequate ventilation, reducing the risk of overheating and prolonging the life of your lithium-ion cells.
ChamRider Tools and Kits
The cables, battery connectors, and control displays from ChamRider are essential elements for those who want to build their own electric assistance system for bikes. Designed to ensure optimal compatibility with ChamRider batteries, these components enable smooth and efficient integration, facilitating the assembly of your custom project.
The cables are highly robust and made with high-quality materials. They ensure optimal conductivity and resistance to weather conditions. These cables are available in various lengths and sections, providing you with the flexibility needed to adapt your installation to your needs. Battery connectors, whether XT60, XT90, or Anderson models, guarantee secure and reliable connections, minimizing energy loss and maximizing your system’s performance.
The ChamRider control display is an essential addition for e-bike enthusiasts. It is easy to install and use, allowing you to monitor your battery’s status, speed, and remaining range in real-time. With its intuitive interface, you can adjust settings according to your preferences, optimizing your riding experience.

Frequently Asked Questions about Chamrider Accessories
Which charger do I need for my Chamrider battery?
Always match the charger voltage to your battery voltage: 36 V batteries require a 42 V charger, 48 V batteries a 54.6 V charger, and 52 V batteries a 58.8 V charger. Chamrider supplies compatible original chargers for all models. The connector type must also match — most models use a standard 5.5/2.1 mm DC barrel connector or XLR.
Do I need a mounting kit for the rack battery?
Yes, if your bike does not already have a compatible rear rack or mounting point. Chamrider offers universal mounting kits compatible with the most common bike frame standards. Ensure the rack is rated to handle the battery’s weight safely — most Chamrider rack batteries weigh 2–4 kg.
Is the Chamrider battery display compatible with all models?
Chamrider displays show charge level (%), voltage, and estimated remaining range. They are compatible with the JST connector system on all current Chamrider battery models. Check your battery’s specification sheet for connector type if you own a model produced before 2022.
