Scope of delivery
- 1x Keeppower IFR26650 3.2V 4500mAh LiFePO4 battery in the selected variant
Note: Depending on the selected option, the battery is supplied as a cell with flat terminal, raised positive terminal or with solder tags.
*Furtheroptions:
- Without extras: Battery cell without additional options, as shown in the main picture.
- Raised positive terminal: A button top (nub) is attached to the positive terminal using a special welding process. This raises the flat positive terminal by approx. 2 mm, similar to a conventional battery. (for an extra charge)
- Solder lug: A metal lug(W: 7.0 mm × L: 30.0 mm × D: 0.15 mm) that is firmly connected to the positive and negative terminals. It is used to solder connecting wires or additional batteries. (at an extra charge)
Versions of the solder tag:
- U-shape: Both solder tags point in the same direction. Suitable e.g. for parallel circuits or for soldering to electronic components.
- Z-shape: The solder tags point in opposite directions. Suitable e.g. for series connections or design-related connection solutions.
Notes on use and distribution
This article is an industrial cell for further processing. The cell is intended for installation in battery packs, battery holders, energy storage devices and other technical applications with suitable protection and charging electronics.
Please note: The cell does not have an integrated electronic protection circuit (PCB/BMS). It is therefore not intended for direct household use without suitable protective measures. Industrial cells are intended for further processing or for integrated use in devices designed for this purpose.
Important: This is a LiFePO4 battery with a nominal voltage of 3.2V. Only a suitable charger for LiFePO4 / IFR batteries with the appropriate final charging voltage may be used for charging. Please also check whether the charger used can mechanically accommodate size 26650.
