6s 5000mah 50c ec5

Great capacity and a ton of power in my tlr typhon. After reading a ton of forum posts, I found out that these are summer if the best quality batteries available on Amazon. I've been through a dozen or so charge cycles and I have to agree. These are nice heavy packs that definitely deliver the advertised capacity and discharge rate. I'll be running exclusively HRB from now on.

I've used HRB Lipos in many aircraft. Their performance is solid with predictable and consistent flight times. Would recommend.

I bought two of these to power my eflite carbon cub z 2.1m airplane and my fms 2000mm beaver. They came well packaged. The balance lead was normal size/shape. I plugged them into my cell checker right out of the box and they were all balanced well and near 50% charge. So far I have about 5 cycles on each battery and they continue to perform great and have no issue balance charging. I'll be buying 2 more.

These are great batteries. I use them in a Freewing F-4 & 262, as well as a eflite F-4. I finally retired one after three years of service due to a dead cell. I charge at 12 amps in a balance charger at the field in the sun. They've never puffed or done anything unpredictable. I've pulled them out at 3.6 volts per cell and they were really hot but no issues. Generally they are cool by the time I'm done charging.

Good

Love these batteries! I have been using HRB for a few years now in all my recent helicopters. They perform well, the price is excellent, and all balance correctly and have low IR. These 5000 mah are being used for my SAB Raw 580. Highly recommend these batteries!

Long battery life

This soft case has taken a beating over the years, dented everywhere and dirty but the capacity was always between 4900-5000mah when charged 3.7v to 4.2v. I never noticed a performance decline, the only thing that would happen is right before it would automatically turn off the power was noticeably almost gone for about 15 seconds which helped a few times because I could maneuver it to safety before it died. All in all the $80 I paid for the battery 3 1/2 years ago got my money worth on over 1100 cycles. This one is probably an outlier, built by the like best person in the manufacturing plant or something lol
