NERF Rival Rechargeable Battery Pack

This battery is NiMH, which is a slight disappointment considering LiPo and LiFe batteries are common these days. NiMH is still decent technology and if you take care of it should last quite a while. It is 7.2 volts and intended to replace the 6 D batteries in your Nerf blaster. NiMH cells are 1.2 volts per cell and Alkaline batteries are 1.5 volts per cell, so by using this instead of Ds youre actually losing 1.8 volts. They could have made a 7 cell NiMH battery which would have been 8.4 volts... but they didnt. Compared to the D batteries, I really didnt notice a difference in rate of fire, accuracy or distance. D batteries are ridiculously expensive and heavy, so this is an upgrade in every sense... less weight, less expense long term. No regrets on this purchase, but Im pulling one star for Nerf using old technology and not having the forethought to add another cell to more accurately replicate the voltage of the original battery configuration. Keep in mind, 4 stars is great... a 3 cell LiPo or some more modern setup would be fantastic. TLDR version: Get it!

My son has the nemesis. Not only does it seem to have more power than the six d batteries, it is much lighter. For my son, this is a big bonus since the nemesis is already quite bulky and a bit heavy. It will also save you a fortune on d size batteries.

I purchased 2 of these and, if youve ever read any review, they work amazingly for any Nerf Rival Blasters that use D batteries. The product came just as advertised and extremely quickly. I plan on buying a couple more soon.

It is very loud and quite annoying. Works well though if you can handle the noise.

First the ad is full of default Hasbro blah blah blah about how great Nerf is. Should stick to the specifics of the item like in this case voltage and amperage on a battery pack. Had read that it was great for the Nemesis too and my Nemesis is what I bought this for. It fits perfectly however, quite a bit weaker then 6 D batteries which in series generate 9 volts. I tested everything fully charged with a multimeter. Batteries were a bit over 9 volts and around 2.5 amps whereas this pack I bought was just around 7.2 volts and just under 2 amps.

This improved our rivals so much. First of all, D batteries are SO expensive! We got this for our nemesis and it saves a lot of headache. I have yet to need to recharge it after countless battles with the kids. It slides in and out so easy! We loved it so much that we ordered another one when we bought the Hera. Works great in that too. My absolute favorite feature of it is how lightweight it is. About a third of the weight of D batteries. If you have any of the rivals that accept this battery pack then you NEED THIS.

Increase dramatically the rate of fire on any of the compatible model. Highly recommended. No longer Keen on using D9 batteries x 4 after bought this .

Totally essential for the Khaos, the power is anemic at best with D cells at full power, and they drain quick, and are expensive. This thing totally woke the gun up. Now auto fire actually hits hard, isnt strained, higher rate of fire, better fps. Glad I got it. There is a youtube review that shows the difference. Id recommend looking it up. Oh, and it weighs NOTHING, takes like 3-4 lbs off the gun.

This battery works great. I bought it with damaged packaging from Amazon and it still performed as it should. I however lost the instructions, so for those of you who may get frustration free packaging, here is how it works. 1) Plug it in 2) Light will be steady red on the charger 3) Blinking light on charger means ready to go In my exoerience a blinking light typically means charging and a steady light means charged. So this seemed backwards to me. The battery is more efficient and lightweight than using standard batteries. You will see a slight performance increase using this (despite the slightly lower voltage it higher current). This battery is also more stsble than doing something such as a lipo conversion. I havr no issues with my 8yo switching it out due to this. Just pick up one of these if you have any blaster it works with. Its well worth it! Here is a list the blasters this works with as well. Comoatible with: Nerf Nemesis Nerf Khaos Nerf Hera

A must have for Nerf Rival enthusiasts. This battery works in the Nemesis, Khaos, and Hera and also works in the Adventure Force Accelerator (non-Nerf brand). They charge in about 2 hours and you get hours and hours of play time without diminished performance at all. These batteries actually give the guns better performance in terms of power, speed, FPS, etc. They are also much, MUCH, lighter than putting D batteries in these guns. There is a significant difference in weight which is huge if you are in a prolonged Nerf game or if you are playing multiple rounds. $30 rechargeable battery trumps buying $15 packages of D batteries over and over again, any day.
