NERF Rival Rechargeable Battery Pack

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.

If you want to get the most out of your Nerf Rival MXVII-10K, youll want to get the rechargeable battery pack to complement the rugged and powerful look of this machine. Youll even save money over time by not having to frequently replace 6 D batteries when they lose power. The difference in velocity of the pellets when using the battery pack and the D batteries is night and day. Make sure you are wearing eye protection and you and your kids can take a small sting from the pellet if you have any exposed skin. More power equates to more fun! You wont be disappointed!

Love this!! If you have a battery operated Nerf rivals blaster that is compatible with this I HIGHLY recommend you invest in this. It slightly improves your blasters performance and makes it lighter (useful when running and dodging foam rival rounds) it comes with a charger for the battery pack and instructions.

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.

Great item dont know how long theyll last I probably longer than the gun. Would have preferred a better charging unit. But at this price you cant complain. My best advice just buy them you will not regret it.

Much better option than using batteries, which would cost a small fortune every time they need replacing

This rechargeable battery pack is compatible with a number of Nerf Rival blasters, including the Hera and Nemesis, the two I have used it with. Given that the Hera takes 6 C size batteries, and the Nemesis takes 6 D size batteries, this battery pack starts to pay for itself after the first couple charging cycles. Not only does it improve your pocketbook over the long term, it also yields slightly higher muzzle velocity (less 10 FPS higher than the regular batteries), and in the case of the Nemesis (it is full-auto while the Hera is semi-auto), a slightly higher rate of fire. The biggest improvement of this battery pack is the weight. It weighs in at about half the weight of its regular battery tray counterparts. Whether you are buying for a child or adult, this is an incredible improvement that will greatly increase the quality of your game. I cannot stress enough how much better the blaster feels in your hands with the extra weight taken off. This pack is a reasonable price at $30. I bought it at $15. Absolutely recommend.

It holds a charge, and is a must have. Unless you want to go broke buying your kid batteries, it’s a must have. My boy has had it a month, and it is still holding up. Well that’s my sales pitch.

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!

Worked for nerf rival mxvii-10k. Took a few hours to charge, but worked as promised.
