We provide professional battery diagnostics, repair, and replacement for electric bikes and scooters. Services include BMS replacement, cell balancing, faulty cell replacement, jumpstarting, and full battery rebuilds. Restore range, performance, and reliability with expert care for your battery pack.
A healthy battery is essential for the performance and range of your eBike or eScooter. If your battery is losing power quickly, won’t charge, or shows inconsistent performance, our expert technicians can help. We specialize in full diagnostics, component-level repair, and battery pack rebuilding. Whether you need a simple fix, BMS replacement, or a brand-new battery, we ensure your ride stays reliable and safe. We also offer mobile service, bringing expert care right to your location across the Bay Area.
Battery Diagnostics & Testing: We start by running detailed diagnostics to measure voltage, capacity, internal resistance, and charge/discharge behavior. This helps identify issues like unbalanced cells, BMS faults, and degraded capacity before recommending next steps.
BMS Replacement: A faulty battery management system (BMS) can prevent your pack from charging or discharging properly. We replace damaged or outdated BMS units with reliable, compatible replacements to restore safe and stable operation.
Cell Replacement & Rebuilding: We replace damaged or weak 18650/21700 lithium-ion cells inside your battery pack. If enough cells are failing, we rebuild the entire pack using brand-new, high-quality cells for improved performance and extended lifespan.
Battery Balancing: When cells in a pack become imbalanced, it affects charge efficiency and reduces range. We balance each cell group to ensure your battery charges and discharges evenly—improving performance and safety.
Battery Jumpstarting: If your BMS locks out charging due to over-discharge, we can safely jumpstart your battery to recover functionality without requiring full replacement.
Professional Replacement: For batteries that are beyond repair or when performance upgrades are desired, we install new, high-quality packs that meet or exceed OEM standards. All replacements are tested, secured, and calibrated for your specific ride.
From repairs to upgrades, we offer comprehensive solutions for eBikes and eScooters.
View All ServicesAdvanced Battery Expertise: We go beyond simple swaps. Our team understands the internal structure of lithium-ion battery packs used in eBikes and eScooters, allowing us to diagnose and fix issues others might miss.
Full Rebuild Capabilities: Instead of replacing your entire battery, we can often rebuild it from the inside out—replacing only the necessary components. This saves you money and reduces environmental waste.
Mobile Service Available: We bring battery diagnostics, repairs, and replacement directly to your location. Whether you're at home, work, or stranded mid-ride, our mobile techs are fully equipped to help.
