This Review is for who want to buy lipos (due to out of them) or want to try out new lipos. I know most of guys update to these beast.
What is R-Line? R-Line is a brand new product line specifically designed for professional FPV racing competitions. It’s the selling version of Toppilot batteries. They are more powerful than other graphene batteries. As We All Know Tattu is Known For Their higher capacity, lower internal resistance and lower Operation temperatures. It is Same As Tattu Top-Pilot Lipo. Its In first Stage Version 1.0 Which Performs Very Well. In the future different versions will also be rolled out to meet the needs of different FPV racing competitions.

At http://www.genstattu.com They are confirming that they are Top Pilot packs, and They are confirming that they are Graphene packs, Which Mean It can Handle More Than 500 cycles(when properly use with care.) so I know we’re already in for a treat with their performance.
I like 12Awg grade wire for some serious amp draws. The Lenght Of Cable is not too short and not too Long. It can be easily useable On 200-240 class quads. It also Comes With Balance connector (protector) which is good to use to save balance lead from props and easily asseable When charging Them. Weight is About 182 (for 1550mah) I honestly use this lipo For race Weight to power ratio is like 180grms of lipo on beast setup.
I don’t have ant Testing Equipment But i have other lipos like bonka, turnigy etc To Compare With I Gernally Fly them on a course and checking for battery sag, Internal Resistance,Build Quality.
Build Quality- As the Tattu is Known For good quality lipos they Directly reflects when You feel then In hand.
Checkig Sag & Overall Performance-I Fly Them around 13-15 cycles each last week. during heat i droped cells to 2.9-3.0v.After 1hr when i Reached Home I Charged Them I was Surprised To see no puff . They are True 1550MAh.This means that the 1550mAh genuinely gives you around 1550mAh if you leave around 20% in the pack as you should.They are Cold when They Land.
Internal Resistance-Comparing Them to Other Lipos They Are Very Minimal IR. I got 2-3ohms in Each cell in R-LINE & Got 3-6ohms per cell In Bonka. The Same Charger Was Used to ensure the results were kept fair.
They are a little heavy Compared to 1500mah Lipos (of course Coz its 1550mah), but provide solid and constant power throughout the pack but the fact the power is still there after 30 seconds Of Serious PunchOuts Thats Why it doesn’t matter. Because of the extra capacity I was expecting them to perform not so good, but I am amazed to say I think they performed better. I had pulled on them in my 2:30 to 3 minute flights.From My First Cycle To Last Cycle They performed same which is incredible.. Now i know the Hype. I Will Definatly Use them In Race..
