Shipping note (important for international customers):
For regulatory reasons regarding lithium-ion shipping, we offer two variants:
-
“Complete set" (200 EUR, with 3x Nitecore batteries + charging distributor): shipping within Germany only.
-
“Cage only" (180 EUR, with charging distributor, without batteries): worldwide shipping. You buy the three Nitecore NL1411R batteries separately in your country — all sources (Nitecore Store, Amazon.com, eBay, etc.) are listed below in the "Shipping and international sourcing" section.
-
NEW in v2: High-current board with gold-plated contacts. Stable current flow even during short load peaks — the continuous mode runs reliably even with sticky motors.
-
NEW in v2: Nitecore 14500 USB-C batteries, 3A continuous discharge / 7A surge. Significantly more powerful than the previously used Keeppower cells (which shut off at about 2A) — no premature triggering during continuous shooting.
-
All three fuses included as standard + storage box. 0.8A, 1.0A, and 1.25A (slow-blow glass fuses) in a practical box set — you install the one matching your model, the others stay neatly stored for later.
-
Three individual batteries with their own USB-C charging electronics. No dangerous series charging, no overcharging, each cell has its own BMS — maximum safety for the camera circuit board.
-
Over 100 film rolls per charge. More than double the capacity compared to the original NiCd batteries — and half the weight.
-
Precise snap-hook mechanism. Secure hold in the battery compartment, quick change without tools.
Compatibility
The battery adapter v2 is designed for the Rolleiflex 6000 series. Which fuse your camera needs depends on the model — all three fuses are included, and the one matching your model is already installed.

Special case — not tested ourselves:
- Rolleiflex 6008 AF
- Rolleiflex 6008 Integral 2
- Rolleiflex 6001 RCC
These three models use a NiCd voltage reading circuit in the camera electronics, which historically had recognition problems with Li-Ion cells. We have not tested the v2 adapter ourselves with these models — it is possible that the new high-current board partially or fully solves the problem, but we cannot guarantee it. If you own one of these models and want to try it out: please contact us briefly beforehand. We will discuss the chances of success and offer a fair return in case of failure.
What's new in v2 (May 2026)
The second generation of our battery adapter brings three substantial hardware upgrades — developed after evaluating the first months of sales and direct customer feedback:
-
High-current board with gold-plated contacts. The new PCB generation also cleanly transmits short current peaks without the fuse mistakenly interpreting them as continuous load. This solves the most common residual problem of old cameras: previously, micro-triggers occurred when hardened motors started up, causing the fuse to trip prematurely — with the new board, the surge current flows cleanly, and the fuse still protects against real continuous load faults.
-
Nitecore 14500 1100mAh USB-C, 3A Continuous Discharge / 7A Surge. The previous Keeppower cells shut off at about 2A continuous current — with a 6008i in continuous mode, or if the grease inside the camera has hardened and the mirror/shutter motor draws more current, that was the limit. The Nitecore cells hold 3A continuously and tolerate short current peaks up to 7A. This ensures even an unserviced camera works reliably.
-
All three fuses + storage box included. Instead of one fuse per variant, you now get the complete set (0.8A, 1.0A, 1.25A) in a small hard plastic box. The one matching your model is already installed in the cage; the others remain safely stored in case you add another camera from the 6000 series later or need to replace the fuse.
Scope of delivery
Variant "Complete Set" (with batteries):
- 1× Battery cage v2 with high-current board (gold-plated contacts)
- 3× Nitecore 14500 1100mAh Li-Ion Battery (USB-C Port, Status LED, 3A Continuous Discharge)
- 1× USB charging splitter (charges all batteries simultaneously)
- 1× Fuse set in storage box: 0.8A, 1.0A, 1.25A (slow-blow glass fuses, IEC 60127)
- 1× Quick start guide (DE/EN)
Variant "Cage only" (without batteries, without charging cable):
- 1× Battery cage v2 with high-current board (gold-plated contacts)
- 1× Fuse set in storage box: 0.8A, 1.0A, 1.25A (slow-blow glass fuses, IEC 60127)
- 1× USB-A to triple USB-C charging cable (charges all three batteries in parallel)
- 1× Quick start guide (DE/EN)
Batteries and charging cables are purchased separately. We recommend the Nitecore NL1411R (1100mAh, 14500 format, USB-C, 3A continuous / 7A surge) — you need 3 pieces. Other 14500 USB-C cells with ≥3A continuous discharge also work technically but have not been tested by us. Any USB-C cable or multi-charger is sufficient for charging.
Where to get the Nitecore NL1411R?
What to do if the fuse blows in continuous mode?
If your camera triggers the fuse in continuous mode with the correct fuse (see compatibility table above), this is almost always a sign of dried grease inside the camera — the focus motor, mirror, and shutter then draw significantly more current than originally intended. Recommendation: schedule a service (CLA) at a specialized workshop like Wiese Fototechnik. During this, the aging capacitors on the camera circuit board are also checked — this is the most common real cause of failure in the 6000 series.
As a temporary solution at your own risk, you can use the next higher fuse rating (e.g., 1.0A instead of 0.8A for an SLX). This slightly reduces the level of protection — in case of damage, the fuse will blow later, which in the worst case can affect the camera circuit board. Acceptable for a transition period until your service appointment, but not recommended permanently.
Why this battery is safe
-
Three individual batteries, no series charging: Each cell is charged individually via its USB-C port. This eliminates the main risk of poor DIY adapters (overvoltage, fire hazard due to missing balancing).
-
BMS in each cell: Protection against overcharge, deep discharge, and overheating — integrated directly in the Nitecore cell.
-
Model-specific fuse: The slow-blow glass fuse matching your model reliably protects the camera PCB from real faults (short circuit, component failure).
-
High-current PCB v2: Separates surge currents (short, normal load peaks) from continuous load (real faults). This keeps the protection intact without the fuse tripping falsely during normal operation.
Important: The batteries must never be charged in the camera's original charger. Use only the USB-C ports on the cells.
