CNHL 10000mAh 4s Lipo Battery 100C 14.8V Soft Case with QS8 Connector Compatible with RC Car Truck Tank Boat Racing Models(2 Packs)

All cells on both batteries came storage charged at almost identical numbers 3.85 they even charged almost identical of each other and cut off the same on both batteries all the cells I've never seen 2 packs that are about exact of each other so far extremely happy I have a fully built X-Maxx running the Max 5 G2 1250kv 22/35 gearing punch 6 weights 35lbs with the batteries I will be trying them in my second X-Maxx fully built running the Max 5 G2 800kv 30/35 gearing punch 6 and will add to my review later with an update

Okay, so firstly, the C rating is the same as most other manufacturers. A TOTAL FABRICATION, borderline an outright lie considering what the C rating is suppose to represent, But most likely some low amp level not even close to real world test was done on a few cells from the batch and "Tada" 95c was slapped on the label. The only thing I can tell you about the C rating is, I had one battery hold strong during a 5 sec 110 amp burst, the other tripped the voltage alarm straight away on takeoff. Now the one that tripped the voltage alarm may have been caused by the issue I describe below. Another thing to note is, the ambient temp played a huge role in this batteries run time in my E - flite Draco. 60 deg F, 20 min runtime with mixed throttle management, 78 deg F, runtime dropped to less than 10min.Secondly, one of the two batteries either had a very week solder point on the EC5 connector, or it just got so hot it unsoldered itself. Or it was a combination of both. My first use of this battery was in my Draco, which I had just flown with the other battery (Same Type). As soon as I took off with this second battery my voltage alarm tripped, so I landed and reset the alarm, then just took off with 3/4 throttle instead of full. The battery did okay, but not quite as well as the first one. The next day I went to charge it and as I was hooking it up to my charger the positive wire lead just slid right out the EC5 connector. No melted plastic or rubber, it just came loose, with all the solder still sticking to the wire but none of it to the connector. I have since resoldered it and it appears to be holding up so far, I just hope the loose connection during flight didn't do anything to degrade the internal resistance of the cells.Other than that, the battery is decent, cell balance was within acceptable limits except when the battery is run near its max for the entirety of a run on a warm day, though even then is was only off by .2-3 volts. While that is not necessarily good, it's to be expected at this price point. I will note that this is the first CNHL battery I have had trouble with. The other CNHL batteries do have similar characteristics with regards to the cells balancing. Durability not so good thus far, but I will see how the first one holds up and how the second one does after the repair.

Excellent product it does what it says it do would definitely recommend

Hands down, the best batteries I have! Great power, long lasting, great price since I caught them on sale. Now the price has gone way up. Perform great, no heat or swelling issues. Saw these on IRC’s YouTube channel and had to give them a try. If your rc needs that boost, these are what you need!

Well made Lipo batteries and the "C" rating is outstanding !!

Already puffed up significantly worried to continue using them.

I bought 4 of these batteries and one was only charging to 90%

Batteries lasted less than 4 months. Buy better quality
