HRB 14.8V 6000mAh 4S Lipo Battery Pack 50C with XT60 Plug Compatible with RC Airplane, RC Helicopter, RC Car, RC Truck, RC Boat

I love this battery. It works well with my hdzero goggles and lasts 8+ hours at least! Charging it is easy with the right tools.

At our R/C flying club a large percentage of electric flyers use HRB batteries in their planes, helicopters, and EDF jets. We've found the HRB batteries to be a good value as they cost a significant amount less than the higher priced brands yet perform well.

I bought these back in 2018 and to this day they still work well. I use them in a quadcopter ad well as several rc trucks and they perform perfect

Works as intended, Nice range, bit touchy on some recovers, but still works very nice, using a helix antenna is the best results for FPV, in my case only

I purchased two 4s 5000 mah batteries and two 4s 6000 mah batteries. All seem to be a little weak on cell number one. That cell goes to a higher voltage than the other cells when charging and to a lower voltage than the other cells when discharging. Cell one is the cell that gets to 3.8 volts first and causes the discharger to shut down the discharge cycle.

Good batteries came perfect storage charge and they hold all cells perfectly will buy again no puffing good power good run time

Died one week after the 30-day period. Charged to 100%, 2 weeks later multimeter shows 3 volts and 0.001 amps. Will not charge. Batteries are not deformed, so I don't know why it failed. Too late to return. I'm hoping manufacturer contacts me to sort it out, but no contact information on the product page or the order. UPDATE: After I contacted them, they requested I show proof of the voltage for each cell. I did that using pics of my multimeter and they sent me a new one. That's pretty good customer service to replace just after the return period. Added a star for that, hopefully the new one lasts longer!

This absolute beast worked flawlessly. Amazing flight time, amazing power output, nothing bad to be said.
