How much current can a NiMH battery supply?
You can charge up to 1.6V max. Only charge the cells after they drop down to about 1.1V. Fully charged NMH cell is typically at 1.4V. If you don’t have a BMS or charge controller, and assuming the 4 cells are all at the same voltage, then you can connect the 4 cells in series; and charge them with the 5V/2A charger.
What voltage is a 7 cell NiMH battery?
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).
What amp should I charge my NiMH battery at?
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.
How many amps does it take to discharge a NiMH battery?
NiMH batteries used to matched by discharging them at 20-30 amps. In general, higher is better with those.
What is 1C NiMH charge?
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).
What amp should I charge my 7.2 NiMH battery?
This means that if you have enough time to charge your 7.2V NiMH battery, then you must charge it around 3 amps or nearby, and if, in any case, you are in a hurry or rush, then, in that case, you can charge your 7.2V NiMH battery at 1.1 amps.
How many amps is a 7.2 volt battery?
Do NiMH batteries lose capacity over time?
NiMH batteries stay at about 1.2 volts for almost 80\% of their discharge cycle. Once alkaline batteries discharge to 50\% capacity, it will be delivering a lower voltage than a NiMH battery. Q: What you NEVER want to do with replaceable batteries? Q: Do NiMH batteries lose capacity over time? A: Yes, but nothing drastic.
What is the difference between alkaline batteries and NiMH batteries?
The main difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than 1.0 volts. NiMH batteries stay at about 1.2 volts for almost 80\% of their discharge cycle.
Does the mAh rating of a battery affect its performance?
A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use. Q: Why are AA and AAA batteries rated at 1.2 volts and alkaline batteries rated at 1.5 volts?
How do you determine the maximum current capacity of a battery?
So, the maximum current capacity can be ascertained by measuring the short circuit current. For a good quality battery, it may range anywhere from 4-7 A which won’t last for more than a few minutes or so.
