Viokef Rechargeable batteries

Reliable portable power lives or dies on chemistry, protection, and how charging is handled. Viokef’s range covers cells for tools and lights, hot-swap packs for equipment, and compact modules for ride-through and small UPS tasks. Below is a spec-driven map you can lift into tenders and maintenance notes.

viokef rechargeable batteries classes and compliance

For handhelds and small devices, viokef rechargeable batteries are grouped by Wh bands (≈10–30, 40–120, 150–500 Wh) with labels showing real watt-hours, recommended charge windows, and cycle life at stated depth-of-discharge. Certification includes UN38.3 for transport and IEC 62133-2/61960 for safety.

viokef lithium batteries chemistries and charge rules

NMC/NCA variants prioritise energy density; LFP focuses on thermal stability and high cycle counts (>2000 cycles at 80% DoD). viokef lithium batteries use CC/CV charging with OVP/UVP/OTP protection and cell balancing; typical charge 0.5–1 C, discharge up to 2–5 C depending on heat sinking.

viokef battery packs formats and connectors

Cartridge (18650/21700), sled (2S–4S) and brick (7S–15S) formats cover lamps, instruments, and carts. viokef battery packs add keyed connectors, recessed contacts, hot-swap options, and optional gas-gauge outputs (SoC/SoH via SMBus/Modbus) to simplify fleet management.

viokef rechargeable power cells field-replaceable options

Single-cell AA/AAA Ni-MH and protected 18650/21700 Li-ion are supplied with matched chargers and cradles. viokef rechargeable power cells are barcode-ready for inventory control and ship with MSDS plus storage guidance (30–50% SoC, cool and dry).

viokef ni-mh batteries low-temperature and trickle duty

When cold starts and simple chargers matter more than energy density, viokef ni-mh batteries with low-self-discharge chemistry handle −10…0 °C start-ups, ΔV/ΔT charging, and safe trickle at C/40–C/50—useful for signage, instruments, and long-stored spares.

viokef energy storage modules small UPS and DC rails

Wall or rack mini-cabinets (typically 12/24/48 V nominal) deliver 0.2–1.5 kWh with integrated BMS, pre-charge, contactor isolation, and communication (CAN/Modbus). viokef energy storage modules include thermal derating tables and cable-drop guidance for closet installs.

viokef backup battery systems ride-through and supervision

For routers, access heads, and control panels, viokef backup battery systems provide brownout ride-through, remote fault pins, and replaceable packs. Specify fuse ratings, permitted float policy (true float vs periodic top-off), and maximum lead length to maintain voltage at end-of-discharge.

Technical specifications and standards that matter

• Nominal cell voltages: Li-ion 3.6–3.7 V (LFP 3.2 V), Ni-MH 1.2 V.
• Charge: Li-ion CC/CV (terminate at set current); Ni-MH ΔV/ΔT with temperature sensing.
• Typical temperature windows: charge 0…+45 °C (Li-ion), −10…+45 °C (Ni-MH); discharge −20…+60 °C (observe datasheets).
• Safety/transport: IEC 62133-2/61960; UN38.3; chargers to IEC 62368-1.
• Protection set: OVP/UVP/OTP, short-circuit, balancing; event logs on smart BMS variants.
• Storage: Li-ion 30–50% SoC, periodic top-ups; Ni-MH cool/dry with occasional maintenance charge.

Applications and integration notes

• Portable lights/tools: high-rate Li-ion sleds with keyed docks; in-van or USB-C charging.
• Signs/controls: Ni-MH where trickle/temperature tolerance outweighs density.
• Small IT/controls: LFP modules on 12/24/48 V rails with monitored outputs and defined autonomy.
• Documentation: record fuse values, cable lengths (voltage-drop), and charger profiles in the O&M pack.

Selection checklist for B2B buyers

1. Define autonomy, load profile, and ambient—this selects chemistry first.
2. Choose format and connector standard; lock polarity and pinout.
3. Publish charging method (CC/CV or ΔV/ΔT), charger interface (dock, USB-C, fixed PSU), and safety timers.
4. Decide telemetry: none, fuel-gauge, or full bus; set test cadence and recordkeeping.
5. Set storage/rotation rules and barcode IDs so stores issue the right spare every time.

How Bankoflamps supplies battery categories without friction

Bankoflamps provides tailored pricing per request, rapid quotes by EAN/MPN, and live EU stock visibility before you place an order. In the client portal you’ll see current lead times, shipment status, and downloadable price lists with validity periods for planning. Trusted customers can operate with post-payment terms up to 30 days. Shipments are consolidated so cells/packs, cradles, leads, labels, and compliance papers (UN38.3, MSDS) arrive kitted the way you requested, and an account manager verifies connector types, charge profiles, fuse values, ambient notes, and documentation against your files so consignments are ready to use across France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands.
