8.4 volts
NiMH batteries can be discharged completely without harming the battery, and they do not need to be charged before storage. Traxxas NiMH batteries are offered with 6 cells (7.2 volts), 7 cells (8.4 volts) or 8 cells (9.6 volts).
How many cells are in a 7.2 V NiMH battery?
six AA cells
This is a rechargeable 7.2 V NiMH battery pack with a capacity of 2200 mAh. The pack consists of six AA cells in two rows and a 4″ lead terminated by a “JR”-style connector.

How do you charge a 7-cell NiMH battery?
How to Charge a NiMH Battery
- Press the [BATT TYPE] button enough times to see this screen. You should have the battery plugged in at this point.
- Press the [START] button.
- For this 7-cell 3000mAh battery, I usually recommend a charge rate of 4.0A; you can charge it slower, but I wouldn’t charge it any faster than that.
What amp should I charge NiMH?
High performance battery chargers like the Traxxas EZ-Peak line with a minimum charge rate of 4 amps are recommended to completely charge high-capacity (3000 – 5000 mah) NiMH batteries in one cycle.
What voltage should I charge a 7.2 V NiMH battery?
between 1.4 to 1.6 V
If the voltage goes beyond a certain specific limit, then it might cause multiple risks; therefore, it is essential to know the voltage at which you should charge your 7.2V NiMH battery. The range of charging voltage is between 1.4 to 1.6 V per cell.
How fast can you charge a NiMH battery?
Fastest Charging If a temperature monitor is used NiMH batteries can be charged at rates up to 1C (in other words 100% of the battery capacity in amp-hours for 1.5 hours).
How long does a Traxxas 7 cell battery last?
I have a Traxxas Slash 4X4 ultimate edition that came with a Traxxas 4 series 8.4 volt 7 cell 4200 mah battery that runs the heck out of my Traxxas for a good 35-45 minutes of pretty fast and steady driving up to around 30-40 MPH before it starts to run noticeably slower and with less power.
Why are LiPo batteries better than NiMH?
The weight/power ratio in LiPo batteries is significantly better. LiPo batteries are noticeably lighter and they can store the same amount or more energy relative to their capacity than NiMH batteries. The power output of LiPo batteries is greater in quality and quantity.
What kind of batteries are NiMH batteries?
NiMH Batteries. A nickel-metal hydride battery, abbreviated NiMH, is a type of rechargeable battery similar to a nickel-cadmium (NiCd) battery but using a hydrogen-absorbing alloy for the negative electrode instead of cadmium. As in NiCd batteries, the positive electrode is nickel oxyhydroxide (NiOOH).
Should NiMH batteries be discharged?
NiMH batteries should always be stored in a charged state. Low self-discharge batteries can be stored up to one year between charges, but standard NiMH batteries need to be taken out and charged every thirty to sixty days even while being stored.
Can NiCd Charger charge NiMH batteries?
A charger that can charge a standard capacity AAA NiCD battery (180 mAh) in just one hour might take 8 hours to charge a high capacity NiMH (1500 mAh) battery. It’s best to ignore such terms and make a rough calculation of how fast a charger can charge batteries.
What is NiMH battery pack?
NiMH stands for Nickel-Metal Hydride, the materials used in some battery packs. Unlike NiCad batteries, NiMH batteries do not use heavy metals that may have toxic effects. In addition, they can store up to 50% more power than NiCad batteries and do not suffer from memory effects.
