HRB2packs 2S 7200mAh Lipo Battery with EC5 Plug 7.4V 120C Hardcase RC Lipo Battery Compatible with RC Car Airplane Helicopter Truck Boat

I ran these in a 1/10 2WD SCT with a 120a esc and high Kv motor Ive used for years and these packs shocked me. I can normally can wheelie onto my lid with good traction off the line if I am not careful but once rolling 10-15mph can go full throttle and have a controllable wheelie. I thought I was going easy and went full throttle at 20-25mph and ended up on my lid skidding. I made another pass and punched it at 30mph and was on my lid again. My SCT was pulling the wheels on pavement at 30-35 mph with these packs! After some time with the packs I was pulling controlled wheelies for 10 yds then sitting it down. My other packs are well known brands in the 5ah 60c range. I was skeptical of these packs 120c rating and I doubt its the full 120c but they pull harder than any pack Ive ran before. They also had good pull for quite a while. I'm impressed with how much these brought my setup to life. I dont have the punch control or timing cranked way up either.The HRB 7200mah 120c pack arrived with the correct storage voltage on both cells. My battery capacity checker showed they were within 1% of eachother. For the IR I measured 23 mohm on one pack and 30 on the the other on an old B6 charger. I have done a few brief runs with them so far and they did fine but will run through a full pack and look through the Castle data and the Power Analyzer to see how they compare to my other packs. I like that sellers are offering 2 packs like this so that you can use them in both 1/10 2wd SCT, Buggie, Truggie or use a series harness and stack them for a 4S setup like in the Arrma lineup.

This set of HRB batteries contain a lot of charge with 7200 mAh. This really allows me to drive for longer periods of time, and that makes running my RC car much more enjoyable.They have a quick discharge rate of 120C, which really describes how fast the charge can be transferred to the car for higher speeds. These batteries are 2S, so they will be slower than 3S batteries but may last longer against somebody using the same size 3S.They fit my Senton just like the Traxxas batteries I have and perform just as well.Excellent batteries at a wonderful price! I recommend them to anybody looking for this type of battery. I love it!

For $65 you get two 7200mAh apparently high end batteries. That's only $33 a piece. If you've priced lithium batteries this powerful you know these are a bargain. They are supposed to have A+ grade cells, longer run time, lower resistance, longer cycle life and lighter weight. There is no practical immediate way to measure most of those claims, but I CAN say they definitely pack a lot of power and do last longer than the 5000mAh batteries I was using in my 1:10 RC truck. They appear to be well manufactured, as the fit and finish looks professional and not like it was banged out by the hundreds quickly. The "manual" that comes with them is worthless. It's not even for 7.4V batteries, and it basically just tells you not to overcharge or mishandle them, with the improper sentence structure to boot. Can't knock off a star for that however. They would be better off not including that however, as it takes from the higher end look and feel of these apparently high quality batteries.

Using to power Traxxas Slash 2WD RC car. Runs like a champ with these batteries.The batteries arrived 75% charged and one of them had imbalanced charges on the two cells. Easily corrected by balance charging before use.Like the solid case around the batteries and the EC5 connector.

I got these two batteries to try out since my current ones on my E-revo is no longer useable. The pair i had were 3s, and knowing that these were 2s packs, i had set my expectations accordingly. So far, it works just well. It charged properly on my balance charger, and no issues with disconnections. The cells were balanced during the charge and held it there according to specs. A few hours of charging (only had one charger at a time set up currently), i hooked it up to my E-revo, and it ran as it should for 2s power. I look forward to going through charge cycles on these and see how well they will work. if this holds true to form, then it should just get better after a few more cycles. So out of the box, these batteries matches the specs and the dimensions as claimed. I had to get an adapter for my connectors. Otherwise, if your "toy" accepts EC5 then, it is plug and charge and play!For about half the price of big mainstream brands, this is offers a good value for a weekend hobbyist.

I’m impressed with the quality for the price. I don’t play with my hobby RCs as much as I used to, but these batteries exceeded my expectations. Charging was as expected and run time is great. Overall build quality looks good and performs just as good as a high dollar option

The Rock Solid HRB 2pack 2S 7.4V 7200mAh Lipo Batteries with the EC5 Plug perform extremely well. The cells are tight and well insulated incased in a lightweight dependable standard sized hard case for protection. HRB did their homework, the battery packs continue to offer consistent run times, the cells discharge and charge evenly recovering from High Amperage Burst tests well within the battery specs. I gave the HRB 2pack 2S 7.4V 7200mAh Lipo Batteries Five Stars across the Board. The HRB Company did a wonderful job, using time tested materials and construction methods to build extremely reliable Battery packs.

I peaked these up, and checked how well they balanced. They are all good I've had expensive name brands that had cells that didn't properly balance with the rest of the pack. I used an E-Maxx, and Rustler as test subjects. The Rustler got really good runs out of these. E-Maxx is just a power thirsty monster, and still got a good run. The Maxx did get them plenty warm on this occasion, but not a worryingly high levels. If you've ever run Nimh's on one you know the heat I am referring to! Still a great deal when you get 2 for that price.
