This is a Pre-Assembled 6 cell, 4200mAh Nickel Metal Hydride Battery Pack.
NiMH Batteries Have A Different Chemistry Than NiCd Batteries So They
Require Different Charging Methods (See ADDITIONAL INFO).
PRODUCT ATTRIBUTES: Pre-assembled NiMH Sub-C size cells for use
with 1/10 scale R/C vehicles
Also great for electric airplane
Offers 50%+ longer run times verses 2000mAh packs
Great for endurance racing
Higher average voltage means more power verses NiCd packs
Ni-MH cells have no discharge memory so there is no need to deep
discharge them by shorting out the cells. This damages the cells.
No need to be recycled, NiMH cells are environmentally friendly
WHAT'S INCLUDED: One Assembled 6 cell, 4200mAh NiMH Battery Pack w/Tamiya Connector
WHAT'S REQUIRED: Charger: Having Negative DeltaV or Zero DeltaV Peaking capabilities
Discharger: Having capabilities to properly discharge batteries
PRODUCT SPECIFICATIONS: Charge Rate: 1A for extended life, 2A for improved performance
10-20 millivolts (.01 to .02V)
Height: 0.96" (24.5mm)
Width: 1.8" (47.1mm)
Length: 5.4" (136.3mm)
Weight: 11.2oz (317g)
Maximum Cycles Per Day: Three, with a 1 to 2 hour rest period
Dead Shorting: Not Recommended
ADDITIONAL INFO: Do Not dead short the cells after discharging or store them with a
resistor across the pack. They do not need this and it damages
the battery pack. Store cells with voltage in them.
Use a digital voltmeter if your charger does not have one, to monitor
the voltage. As soon as the voltage stops rising, the pack is
charged. Do not let voltage drop like you would with NiCd cells.
Charger MUST be able to adjust the negative peak charge rate.
Heat or overcharging will deteriorate or damage NiMH cells.
