EVDrive is a Portland manufacturer of ultra-high-performance EV battery systems and powertrain components. We design, build, and validate battery modules, liquid-cooled packs, the BetterBMS, and complete drive systems in-house, for OEMs, startups, and builders in specialty vehicles, racing, marine, and heavy equipment.
Start with a quote: tell us your envelope, energy target, and timeline, and we will tell you honestly whether EVDrive is the right fit.
Every module, pack, and controller is developed, validated, and built under one roof. The same team that designs the cell architecture writes the firmware that protects it. This is what a procurement engineer can specify with confidence.
Ten years of in-house R&D on the standard 21700 cell, engineered for class-leading power and energy density. Priced for performance buyers who need the cell to keep its promise lap after lap, not the cheapest watt-hour on the table.
Complete packs designed, thermally managed, and validated in-house. Liquid cooling holds cell temperature where the chemistry stays happy under sustained load, the difference between a number on a dyno and a number that survives a full session.
Our flagship battery management system, hardened across five years inside EVDrive packs before it ever shipped. Sold to builders and small OEMs alike, with cell-level monitoring and fault tolerance carried over from real performance deployments.
The Smart Power Distribution Unit brings contactor control, fusing, and power management into one integrated module alongside the BMS. In active development toward commercial release, available now by inquiry for programs that want to design it in early.
As battery prices have fallen, most of the market has chased the low end. The buyers who genuinely need maximum power and energy density, performance programs, integrators, and manufacturers, have fewer and fewer suppliers built for them. That demand has not gone anywhere.
That is the tier EVDrive is built to serve. We are not competing on price with commodity packs. We build the cell architecture performance work demands, for buyers a commodity pack was never meant for.
"Most of the market optimizes for price. We optimize for the performance a serious build cannot get anywhere else."

BetterBMS is the battery management system EVDrive spent five years developing inside its own performance packs. It now ships on its own line to builders and small OEMs who want the same supervision EVDrive trusts on record-setting hardware.
Real differences in how the system monitors, protects, and integrates, not a checkbox war.
BetterBMS monitors and balances at the individual cell, surfacing a weak or drifting cell before it drags a whole series string. Where a sport-tuned controller is built around engine and powertrain logic first, battery supervision is the entire job here, so the resolution and balancing headroom are sized for large performance packs, not retrofit onto an EMS.
Five years of real performance deployments shaped the fault handling: redundant voltage and temperature sensing, defined safe-state behavior on a sensor or comms fault, and contactor control that fails closed-down rather than guessing. The protection logic was tuned by packs that actually ran hard, not only on the bench.
Cell chemistry, series and parallel layout, current limits, thermal thresholds, and charge profiles are all configurable, so the same controller fits a one-off build or a small production run. You are not locked to a single pack topology or forced into a closed ecosystem to make changes.
BetterBMS is engineered to drop straight into EVDrive modules and packs, the tightest pairing on the market because both come from one team. CAN-based integration, field-updatable firmware, and direct support from the engineers who wrote it mean you talk to the people who built the system, not a reseller's queue.
From a single validated pack to a complete integrated driveline, EVDrive engineers to the program's requirements with the discipline an OEM expects.
Battery and powertrain engineering guidance on a time-and-materials basis: architecture review, cell selection, thermal strategy, and BMS integration. Typical rate $150–$200/hr.
Under our engineering services, EVDrive takes on a small number of fully engineered custom builds each year. These are not budget conversions. You are paying for engineering that shows up on a record sheet, and you pay accordingly.
EVDrive's 45 kWh liquid-cooled pack set a top-speed record on its very first run. The thermal and energy budget held under maximum load, exactly what the pack was engineered to do.
Also in the portfolio: a Pikes Peak hill-climb racer and marine electric conversions, shared as sanitized case studies to protect client detail. Full write-ups added as photography is released. See all custom premium builds →
Share your envelope, energy target, and timeline. We need the specifics so we can understand the scope and tell you, honestly, whether EVDrive is the right partner for the work.
