Description
⚡ PRE-ORDER OPEN — first run lands end of 2026
THE DON is our NMC line and the highest-voltage pack we build. Pre-order now to reserve a place in the first run — you will get a real build date as the run is scheduled, not a placeholder.
⚠️ Read this before you order
THE DON has no BMS cutoff. It runs an active balancer only. That means the pack will not shut itself down if voltage drops too low. You are responsible for monitoring voltage, and a voltmeter is not optional on this pack.
This is a deliberate design choice for maximum current delivery — no BMS in the discharge path means nothing limiting your output. It also means this is a pack for experienced installers, not a first lithium build.
Chemistry
NMC — nickel manganese cobalt. Higher voltage ceiling and higher power density than sodium ion or LTO.
Charging
- Charging window 14.8 – 16.6V
- Hard limit 16.6V — never above
- Nominal 15.3V
- Minimum 200A high-output alternator recommended
- Verify your regulator ceiling before ordering
Discharge
- Constant 24C
- Pulse 40C at 50% SoC to 2.7V per cell
Discharge figures are from cell-level testing and are confirmed on the production pack.

Cell Power Ratings**
15.3V Charging (Recommended nominal)
- 50,600W – Standalone (Burst <5s)
- 39,500W – Standalone (Burst <15s)
- 32,200W – Standalone (Constant)

* True Amplifier Rating is the expected power support at 80% amplifier efficiency — what your system actually sees.
** Cell Power Rating is the raw power pulled from the battery before amplifier efficiency is applied. Projected from cell-level testing (2,640A continuous at 24C, 4,400A pulse at 40C) and confirmed on the production pack.
Installation requirements
- Pre-charge to your system voltage and wait 24 hours to confirm no voltage drop before installing
- Negative cable off first, positive off second. Positive on first, negative on second
- Mount securely, away from heat and water
- Stand-alone pack — do not mix with other chemistries
- Professional installation required. This is not a beginner pack
- Never charge below freezing
Warranty
1-year limited warranty on defects in materials and workmanship. Not covered: over-voltage above the rated maximum, deep discharge below recommended levels, improper installation or modification, physical damage, water damage, or short circuits.
Register your pack after install — name, address, phone and installation photos showing battery placement, wiring and fuse location.
