Dengera Pro. Battery Recovery System.
An active capacity recovery device engineered specifically for the punishing ultra-high current discharge profiles of agricultural drones. Going beyond simple voltage balancing, it diagnoses and corrects thermally-induced asymmetric internal resistance (IR), coulomb drift, and lithium plating.
Batteries Pushed to the Limit.
Heavy payload maneuvers demand massive current draws (High C-Rate) in seconds. The core issue is not just chemical fatigue, but that this fatigue happens asymmetrically across the pack, leading to a compounding cell imbalance.
Thermal Gradients & Asymmetric Aging
In tightly packed drone batteries, core cells dissipate heat slower than outer cells. This thermal gradient under high currents leads to asymmetric cell aging, creating permanent capacity and internal resistance (IR) mismatches.
The Onboard Balancing Bottleneck
The passive balancing current of the onboard BMS (typically 50-100mA) is far too weak to correct massive voltage deltas during ultra-fast field charging. This voltage gap compounds with every flight cycle.
Premature Cut-off Limitations
As cell imbalance (Delta V) grows, the weakest cell hits the low-voltage cutoff during flight, or the strongest cell hits the high-voltage cutoff during charge. The BMS safely cuts power, creating a massive artificial loss in usable capacity even if the pack holds energy.
Industrial Battery Engineering.
The high-resolution hardware architecture we developed for defense applications and giga-watt scale energy systems forms the core of Dengera Pro. We don't just build chargers; we engineer battery chemistry.
Active Repair Cycles
Instead of merely bleeding off high-voltage cells, Dengera Pro applies targeted charge-discharge micro-cycles to chemically refresh the pack.
1 mV (0.001V) Cell Precision
Commercial devices accept a 50mV (0.05V) delta as 'balanced'. Dengera Pro uses high-resolution ADCs to equalize the entire block with 1 millivolt (0.001V) accuracy. This extreme micro-precision at the end of the discharge curve prevents premature BMS cut-off, unlocking 100% of the true usable capacity.
Capacity Regeneration
Restores the usable capacity of batteries that have been prematurely locked out or flagged as 'damaged' by the internal BMS for safety reasons.
Scalable CMS Architecture
You are not limited to a single device or a single battery. Thanks to our distributed CMS infrastructure, you can connect multiple battery packs in your workshop simultaneously and balance them in parallel, multiplying your operational speed.
3 Simple Steps
No need to train your staff in advanced battery chemistry. Dengera Pro fully automates the industrial recovery process.
Open & Disconnect
Open the top cover of the drone battery and gently disconnect the original BMS socket from the cell block.
Plug Dengera Harness
Connect the cells directly to the Dengera Pro hardware using our provided plug-and-play intermediary cables.
One-Click Start
Select the batteries from the interface and click 'Start Balancing'. Our 1mV-precision system handles the rest.
Flawless Compatibility
Designed to work with all popular agricultural drones and cell chemistries (Chemistry Agnostic). Full support for up to 14S packs (18S coming very soon).
Supported Models: DJI Agras T20, T30, T40, T50, T70, T100 | XAG B13960S and all other standard 14S agricultural drone batteries.
Designed for Technical Services.
Don't scrap defective batteries returning from the field. Establish a high-margin 'battery refurbishment' model for your dealership or repair shop.
- Achieve massive operational profitability by recovering batteries destined for scrap.
- Provide clients with detailed cell-level analysis reports to prove capacity degradation and recovery.
- Despite advanced hardware, the minimalist operator interface requires zero specialized technical training.
