ProTek RC 4S 130C Low IR Si-Graphene+ HV Shorty LiPo Battery (15.2V/6400mAh) w/5mm Connector (ROAR Approved)
About this part
ProTek RC 4 Cell LiPo Battery 15.2V High-Voltage Performance
The ProTek R/C 4S Shorty 130C Low IR 6400mAh Silicon Graphene+ HV Battery is a great option for 1/8 scale racers looking for a high capacity, high output and incredibly COMPACT 4S battery. Weighing approximately 440 grams, the 4S Shorty is almost 13 grams lighter than the PTK-5118-22 5600mAh 4S pack with more capacity! This offers more capacity output, in a compact shorty length that is perfect for weight conscious racers.
ProTek R/C Silicon Graphene batteries are the next step in the evolution of LiPo battery technology. Silicone Graphene construction offers improved efficiency, lower operating temperatures, lower internal resistance, better run time, increased cycle life and increased voltage! While these batteries are technically LiHV cells, they can still be charged with a standard LiPo charger. The overall voltage and capacity will be slightly less than if charged to LiHV specs, but the performance will be better than a standard LiPo thanks to the reduced weight and low internal resistance.
When compared to standard LiPo and LiHV, Silicon Graphene cells deliver an array of benefits! Lab testing has shown that ProTek R/C Silicon Graphene packs have double the cycle life when charged at 1C rates, and can be charged at higher amp rates, with less risk of damage to the pack. More importantly, the discharge curve is flatter, meaning the cells maintain higher voltage throughout the discharge cycle - with no significant drop off. Additionally, when compared to conventional LiPo batteries Silicon Graphene batteries are lighter, providing a higher capacity per gram ratio. With 7.6V nominal voltage, 100C discharge ratings, incredibly high charge rates and ten different models to choose from, ProTek R/C Silicon Graphene packs are perfect for racers and bashers that demand the absolute best.

The hard battery case came loose at the joint in the middle.I bought it at 2/18/25.I sent an email to Amain support and they haven't responded. Update, Amain replaced it but the same issue one month later. I don't know if I am under warranty
A year or so ago I had good luck with the protek 4S shorty batteries. However, the ones I have gotten in the last year have all puffed the case open after a couple months of use. I will be giving some other 4S shorties a shot before buying anymore of these.
Batteries were used in a buggy and cases cracked after 2 races. The cases are maxes from a really cheap thin plastic and I do not recommend them to anyone.
Awesome batteries. Allow for better weight placement on the chassis.
Best bang for you buck. I highly recommend this battery to anyone looking for a great battery for 1/8 off road electric buggy.
Reviewers consistently praise this 4S shorty LiPo's power, punch and run time, with several noting it balances weight well in buggies and truggies. The most recurring problem is the hard case: multiple owners report cases cracking, splitting or the pack puffing within weeks to months, with some describing the plastic as thin and one reporting high resistance in a cell. Several reviewers say Amain replaced failed packs and handled warranty claims promptly, though one reported no response initially and another felt the price was high for the case materials. Opinions are split between strong recommendations and frustration with build durability, and one review refers to a Ryft build and another to a truggy setup.
- + Strong power and punch
- + Long run time
- + Good weight placement in buggies
- + Responsive warranty support from Amain
- − Hard case cracks or splits
- − Battery puffing after use
- − Thin case plastic
- − High price for build quality
