These are awesome and do exactly as advertised! Have 3 coolook batteries and 3 coolook dummies in my dartzone spectrum and the rev is significantly higher and quicker! Wish I had a chronograph! Don't have to split the blaster apart and change out a bunch of parts, so if you don't want to actually mod these batteries are for you!
Shipping was smooth and fast as per usual; OOD packaging was good and it comes in the plastic packaging seen in youtube videos. Shipping price is also pretty competitive
Before the rest of this review I wanna disclose this first: these batteries are 3.2 volts / each PRE-charged. Fully charged they are around 4.2V/each, as I have found out from OOD. Do not use on stock blasters that you can’t run the risk of breaking; These batteries are safe for YOU, but isn’t guaranteed safe for the longevity of your blaster. And do not mix these with standard AAs (alkaline or NiMH) or any other chemistry aside from dummy batteries and LiFePo4 batteries in the same blaster.
These work great in my worker hurricane and all of my stock DZ / Nerf blasters. Sizing of these is pretty much identical to off-the-shelf standard AAs. They bump rate of fire and FPS by about 5-30% with 2 of these and 10-40% with 3 of these in a stock 6V blaster. However as expected the stock blaster’s flywheels did shut off if revved for too long and shut off especially quick in my rapidstrike (which is full auto) when fired, except for my worker Hurricane. The worker Hurricane and other blasters wired for 14500 IMR-style batteries should work flawlessly with these batteries. TLDR; my review mirrors that of Captain Xaviers and justajolt’s youtube review of these.
Charging these usually take less than 10 minutes with the Coolook IMR charger; usually less than 5 minutes was enough for me.
Overall these work exactly as intended. Like almost everything at OOD, Pricing is very competitive even after shipping costs and the shipping itself was smooth and swift.
Super cool little batteries, nice jump in power without physical modifications.
These changed the way our weak Star Wars Blasters worked. They have more voltage and current going to the speaker and 3 or 4 lights in both of the Flywheelers Nerf made so we put in 3 instead of the recommended 2 and 2 passive. We are adults though so we don't rev the entire game and they are used sparingly in our matches. Drop In Performance is awesome.
I wouldn't run 3 in a 4AA box in a blaster that doesn't have other electronics in it as you will definitely over volt if you are reving an entire game using it as a primary or abusing the trigger.
In other blasters that don't have lights and sound you get a slight boost with just 2 and 2 passive in 4AA box and it's honestly great.
The Star Wars Blasters were just made without enough voltage to go around and so the motors don't spin up enough with the included "6V" required to even turn on the blasters on alkaline or even using 2 of these.
Super easy to run 3 in a stryfe for a high power upgrade
yeah its cool
Coolook LFP 14500 battery 2-pack (AA sized Lithium rechargeable)
So much better for foam flinging than AA batteries I got 4 of them and I'm definitely getting at least 6 more to use with any flywheel blaster I don't wanna put a lipo in for a decent power boost with no tinkering.
These gave a mild performance boost to my stock stryfe while being still reversible back to stock. Make sure you buy the two dummy batteries as you are not intended to just 1:1 swap AAs.
I built a Stryfe with Honey Badgers, Worker standard wheels and cage, a genuine 21A Omron switch, and 18 gauge wire. It runs on two or three of these batteries depending on FPS allowances of the game. The metal thumbscrew I added lets me adjust this on the fly. Excellent for super basic Stryfe builds!
I bought 6 of them.At the 3rd charge, 2 of battery were broken, when i put them into charger, no lights on.
So I got 4 of these batteries for my AF spectrums and a DZ vulcanator. I've tried them in both. It really adds some rev and power that 6AA don't give you. Guess what...according to all the research these will "wear out your motors/electronics faster"....I play probably once a month maybe for 2hrs and for a $25 blaster to go belly up its worth the risk...so unless you are holding down your rev trigger constantly for the entire length of charge on these batteries you're not gonna have problems...and if you do well you're out $25 for a blaster. Honestly, the amount of time it would take to rewire and change out motors and circuitry and maintain lipo battery packs isn't worth my time currently.
These are insanely powerful! It’s like batteries got injected with steroids. If you’re not wanting to use LiPo batteries for your modded blasters, these are a good choice!
Out of darts is amazing as always. If your into foam flinging or anything related OUT OF DARTS can more than likely fill your need.
Works well. Using only two of these with my stryfe yielded about the same performance as 4 AA batteries. Might be best to use a third one but with the thermistor turned off to better results
Great in the hurricane. If you're replacing motors and flywheels, probably worth going lipo instead.
Worked well in the hurricane
These are perfect for my Worker Hurricane Blaster.
Awesome little batteries, they are a much safer alternative to IMRs while barely compromising on power, My only complaint is that I wish they weren’t in packs of two but that isn’t OOD’s fault. Perfect five out of five stars
Wish i had a stock pile, so years down the road I’m not worried if can still find them for sale. They do last a long time if you take care of them properly . Still use the original 4 I got a year ago
They work awesome, I know this shouldn't be a permanent mod, but sure is fun to use
Awesome basic upgrade for any flywheel blaster. Not as good as doing a lipo and a rewire, but these do suffice.
Coolook LFP 14500 battery 2-pack (AA sized Lithium rechargeable)
Works great, improved performance without using LIPO’s.
Two Coolooks and two dummy cells and my new Nerf M41A sounds and performs great.
They work as they are supposed to.
They're good batteries overall, use 3 and a dummy cell with hasbro blasters or 4 with DZ's to get a good punch out of them. I can't recommend them enough, if you do a full rewire but want to stay in the 90-110fps range
3.2v per cell. Safer than IMR's. Slap 3 in a demolisher with one dummy cell and bam, better performance. Love these! A+++++++++
With these batteries I can, with minimum modification, get most nerf flywheel blasters up in the 100-120 FPS range.
3 of these are prefect in just about every nerf flywheeler! Instant power upgrade to 100-105 FPS with fresh waffle head darts. RoF on full auto blasters is also increased. Would recommend 10/10
It's a very easy drop-in upgrade to a stryfe. It won't help accuracy but boy will it roar.
