NERF Rival Rechargeable Battery Pack

I am using it in a Nerf Nemesis. It is much lighter than using 6 D batteries and much convinient. Also, shoots a bit harder with the battery pack, but not with much.

This thing powers the nerf gun to the lecture level. The rate of fire must have doubled and the velocity is significantly different than off the shelf batteries.

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!

Battery life is pretty good. I managed to use it off and on for a few weeks before it finally died. Highly recommend it will save you some money on batteries in the long run and maybe right from the start.

Excelente compra

I purchased 2 of these for guns. Charged them fully when they came and still havent recharged. It has been nearly 5 months. The boys go through streaks of playing for days with them and then intermittently. Added bonus is the gun is lighter with this rechargable battery vs regular batteries. Great purchase.

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.

for the ones who dont wanna mod or spend a ton on batteries. the writing was on the wall when I bought a hera, some random Saturday DAD my gun wont work can you get batteries? nope not this guy

I used it for my son right out of the box and it worked. So nice I don’t have to worry about those disposable batteries which will eventually kill our Earth. It will save a ton of money too. One charge lasts almost as long regular D batteries. Do yourself a favor and buy these. You won’t regret it. Don’t throw away instructions. Flashing light means it’s fully charged. The gun should be closed properly to work. I initially did not close it and thought that it’s because the batteries were useless. It was my mistake.

I have 3 of these and they are a no brainer. I will probably be buying a forth in a bit as I just bought a 4th blasters that will accept one of these. They are WAY lighter than the C or D cell batteries, they seem to have decent play time, and you can just top them off so you are always getting the best performance, you dont have to worry about throwing away alkalines that still have some life left but you know arent giving you the zip that you want.
