Traxxas 2972 EZ-Peak Plus 100 Watt NiMH/LiPo Dual Charger with iD System

Traxxas

Based on 492 reviews Check latest price

Product description

Simple. Fast. Just plug in a pair of Traxxas iD batteries and press Start. Traxxas’ exclusive iD technology eliminates complicated charger programming by automatically configuring and optimizing the charge settings for Traxxas iD batteries. The EZ-Peak Dual charges two batteries simultaneously at up to 50 watts (4 amps) each, or switch to High-Output mode to charge a single battery at the maximum 100 watt (8 amp) output. Faster charging means you get to spend more time behind the wheel. The EZ-Peak Dual puts out a full 100 watts of power that equates to 8-amps of charging horsepower. It’s a twin turbo-equipped charger. Traxxas iD LiPOs (4000mAh or higher) charge nearly 2x faster in High Output Mode. The EZ-Peak Dual isn’t just for iD LiPOs; the Multi-Chemistry nature of the charger means LiPOs and NiMHs can be charged at the same time. Advanced Mode opens the door for backwards compatibility. This allows EZ-Peak Dual to charge any Traxxas Power Cell battery equipped with a first-generation Traxxas High-Current Connectors and Traxxas iD batteries independently or simultaneously. There are two balance ports built into the charger for Traxxas LiPO batteries equipped with external balance leads. Take full advantage of the 8-amp output and experience the pinnacle of charger flexibility and power. With iD Auto-Battery Identification there’s no need to worry about the battery chemistry or capacity. EZ-Peak Dual identifies the type of battery and its capacity. EZ-Peak Dual also cuts down on wasted time by eliminating the hassle of programming and using complicated setups. Just plug an iD battery in and press Start. That’s it! Keeping with the simplicity and ease of use, the iD system eliminates fragile balance wires and clunky balance leads. The iD system streamlines the entire charging experience.

  • Charger recognizes Traxxas iD batteries to automatically program and optimize charger settings

User questions & answers

Question: Will this automatically determine the charge rate required for a different brand lipo batteries
Answer: No, you will have to select the proper Amperage, which is easy. Simply set it as close to the mAh rating of the battery as possible. If you have a 2000mAh LiPo, set the charge amperage to 2Amps. If you have a 4000mAh LiPo, set it to 4Amps, etc...
Question: Does it work for the Rustler batteries
Answer: In short, yes. It will work with any 2S or 3S LiPo (7.4V or 11.1V). It will work with any 5cell to 8cell NiMH as well. Your batteries do not 'need' to have the Traxxas ID plug. You can use the standard Traxxas Plug as well. And if you don't have either of those, then you can use an adapter to go from the Traxxas Plug to a plug of your choice. Here is a link to some adapters that you can use. (Keep in mind that there is a 2S and 3S JST-XH plug balance port behind the front flap/cover, which will allow you to connect your standard LiPo batteries)http://www.amazon.com/dp/B01605T9OQhttp://www.amazon.com/dp/B016065X72http://www.amazon.com/dp/B01606EC6Ahttp://www.amazon.com/dp/B01606KNKYhttp://www.amazon.com/dp/B016072F18http://www.amazon.com/dp/B016075GEGhttp://www.amazon.com/dp/B016078OF4http://www.amazon.com/dp/B01607BQTAhttp://www.amazon.com/dp/B01607M9C8
Question: How long would it take to charge a 25c 7.4v 2 cell 10,000 mah lipo battery
Answer: This charger can be switched to High Output Mode where 1 port will use all 8Amps/100Watts of power. So you can charge your 10,000mAh (or 10Ah) battery at 8Amps. 10Ah / 8A = 1.25Hours
Question: Will this charger work for Traxxas 7.2v 2200 mah Lipo batteries? Is there any mah that is too low
Answer: Not sure, but be careful with this seller. One side did not work and I sent back 3 days later in original box and they kept $20 from the refund!!

User questions & answers

Question: can you charge other brand batteries in this charger
Answer: I have this charger and it will not charge any brand battery except the Eneloop battery. Do not Buy it for other batteries, it will not work. I bought it based on reviews and that I have about 20 NiMH batteries of various brands. Not one of the 20 would charge on this charger.
Question: Must you charge 4 batteries at a time OR can you charge, say 2 with 2 open slots
Answer: The Panasonic BQ-CC17 can recharge 1, 2, 3 or 4 AA/AAA cells at once. You don't need to charge in pairs like in the case of old MQN06 charger.
Question: i just received the charger and i do not see any indicator lights on mine. anybody
Answer: Just to update this - the chargers shipping now have hidden lights (unlike the product picture). To see them charger must be plugged in with batteries in place. NOTE: To clarify the paper comment - the batteries are shipped in the charger in the charging position. Before first use, remove all four batteries and you will find a small piece of cardboard paper at the top covering the positive charging contacts. This paper is to be discarded. Put the batteries back in position, plug in charger to working circuit and you will then see the now hidden lights under the white plastic "skin" below each battery. This is still true as of 11/2018.
Question: What is the difference between the Panasonic K-KJ17KHCA4A Eneloop Pro vs the Panasonic K-KJ17MCA4BA? Which is a better choice to buy
Answer: The pro cells hold about 25% more capacity under use before you have to charge it. That translates to longer run times for things like hiking GPS and high powered flashlights and wireless microphones in constant use. The trade off is that the pro cells don't retain a charge when stored which is good if you normally plan to drain the battery within a few days of charging it. In a TV or DVD remote control, the pro cells would have to be charged at least once every several months, where the regular cells will last for years without charging in remote controls that are not used daily. So far, I have never had an Eneloop battery ever leak, where I have had several expensive remote controls and headlamp LED's destroyed by leaking modern alkaline batteries. Modern alkaline batteries will often start leaking while still performing and still many years before the best used date has arrived. Modern warrantees for alkaline batteries only cover the battery that fails to perform, not the expensive device that was destroyed by the leaking alkaline battery. I have had several Duracell batteries start leaking while still unused in the original package stored in a cool dry place (basement) and still have a few years before the best used date has arrived. Today's alkaline batteries are junk. The standard Eneloop battery seems to be the most dependable battery I have ever found. They cost more, but the extra cost is worth it. Other brands of NiMH batteries I use often don't hold a charge in storage. The supposed lower voltage compared to alkaline is not the whole truth. Under extreme low power loads, alkaline battery voltage is higher, but under higher loads like cameras and flashlights, the alkaline battery voltage drops lower than NiMH battery within a second of the time the load is applied and then goes back up to resting voltage after the load is turned off. After an alkaline battery looses around 20% of its original charge, it is performing worse than a rechargeable NiMH battery and many devices like cameras can't take that drop in voltage.

User questions & answers

Question: Can the charger be used to charge other brands of Ni-MH batteries. A little tired of each brand claiming only their charger will do it properly
Answer: Yes, a Ni-MH battery is a Ni-MH battery. They say that their charger can only charge their batteries because of legal liability reasons, and so you'll but more of their batteries after you buy the charger ;) Most chargers can detect when it's fully charged because the voltage drops a little when it is, as in 5 mv to 10 mv. The percentage of how much power a battery has is from the voltage. e.g. the peak voltage of most high capacity Ni-MH batteries is between 1.45 to 1.55 volts. I know it says it's nominally 1.2 volts but I think that's when it reaches 0% just like a lead acid batteries in vehicles, they're fully charged at 13.2 volts even though they're called 12 volt batteries. I don't understand the world! I mean a smaller number for gauge means it's thicker?! That doesn't make any sense at all! D: I like turtles.
Question: Are there any differences between this charger and the NC-MQN06U not in terms of form factor but in terms of functionality and charging
Answer: The new BQ-CC17 charges each cell independently. The old MQN06 charges in pairs only. Other than that, they have exactly the same charging current (hence charging time).
Question: Should you remove the batteries from the charger once they're charged or can you leave them on
Answer: Ditto the 11/30/2014 comment, no need to leave them on once they are charged; I usually remove them once I see they're charged.
Question: If I use these for photography flashes -- why would I use the pro version instead of the regular ones? I'm confused as to how they are better
Answer: The Eneloop Pro have a higher capacity than the standard ones (roughly 2,450 vs. 1900, about 29% greater); all other things being equal you will get more flashes per battery change. Note that different generations have different performance ratings. In some cases the Pro are rated for fewer charge cycles, however; the Lite versions when available have even less capacity per charge, but more charge cycles.

User questions & answers

Question: can this plug into a a standard 120v wall outlet
Answer: This is designed to plug into a standard wall outlet found in the US. Let us know if you have any further questions. Thank you,
Question: Will this work on lithium if it doesn't have a bms? will it recover dead batteries
Answer: It will work with a lithium battery that does not have BMS. The tender itself is designed to keep the charge at a safe level for a 12 volt lithium battery, so you can leave it plugged in. If you need to recover a "dead" lithium battery, I would go with a more advanced charger found that is built to not only maintain, but recover batteries, like an Optimate. Please contact us directly for more information. That doesn't guarantee that it will recover any low lithium battery as the cells could have been damaged in the process.
