Blomiky 7.4V 600mAh 10C Li-ion Rechargeable Battery Compatible with WPL C24-1 C14 D12 RC Crawlers / D12 Battery 2

Really good deal - 3-pin balanced charging with a nice SM-2P power-out connector for delivering all 7.4 volts in serial for a great output without much voltage sag, and without overheating even under heavy loads, like continuously-running gel blaster motors.And even though the listing says 600mAh capacity, what's delivered is labeled as 800mAh capacity, a third more for your money. Now I've not run a capacity test on these, although I could, and someday might if I'm bored enough, but I believe the 800mAh label on the Tyvek PVC wrap over the pack, simply based on the performance. Higher Amps mean less voltage sag at a given draw, and that's what I see versus the 500mAh and 600mAh packs. Higher Amps mean longer service at the same draw, and that's what I also see. Pretty sure these are every bit of the 800mAh. Oh, and EVERY time I've ordered these (at least 3-4 times), they've come in at 800mAh, not 600. So I think the product has been upgraded and the ad text just needs to be changed to reflect that. The pictures in the ad show 800mAh, just like the ones I received, thus I didn't post a pic of mine - they match what's in the ad.It's a great size in which to have so much capacity. These are the perfect 14500 cell pair (= 7.4v) package size battery to fit in most of your smaller devices, with a really common SM2P connector to fit most anything. And 800mAh is about the most you're going to get out of a pair of 14500s - you need to jump to the 18XXX size cell pairs to get to 1500-2200mAh capacity at 7.4 volts.So you're getting your full bang for the buck. They're really well wrapped and the wires are really secure and well soldered/glued into the plugs and it all connects universally like a dream. On the chargers, you have a beautiful auto-shutoff at correct voltage (yep, I metered it) and everything is auto-sensing.There's no LiPo here, so no bulging or problems - it's a nice, solid cylindrical Li-metal cell that can take some punishment, both physically and with high C-rate of discharge: all without problems or issues that I can fine.Really great batteries, and you get a PAIR of them at a really good price. Frankly, I've stocked up on these a bit, and now I always have one charged and fresh for whatever is at hand to play with. (The kids switch toys a lot!)Totally RECOMMEND these batteries, and I've bought other Blomiky branded batteries that I find to be of equally high quality and perceived safety.

Works great on the WPL C24 crawler. Connector matched the factory plug, but would be a good idea to check yours before plugging it in.

Connector was different than my RC car. Did not work even though description said it should.

Long lasting and powerful, does the job.

Needed for a toy for my son . Fit great and still working strong

Overall good product. Standard for rc

I love these I am so glad you have them than you

I have the model of Astoy in the description, but these do not fit at all, not sure what gun they are for. A waste.
