Good battery for about six months, one cell wouldn't take a charge until finally puffed the pack.
Batteries were good till five months! The power leads detached itself from the cell rendering the fully charged lipo useless! one battery shorted out and catched on fire. My hooby king lipos outlast theses for much cheaper price. I will absolutely never buy ECO brand lipos again. Sorry A MAIN HOBBIES.
I run these in my 8ight E 3.0 with a Tekin Gen 2 and a 1900kv motor, they have plenty of punch and can make well over 10 minutes. Couldn't be happier and can't beat the price!
great batt for the price. good small package with a lot of punch. I think that the 35c rating is way off they feel like my 70c all day long
Got 2 of these and could not be happier,long run times with a mod motor and way better than gens ace...
Excellent battery! I'm using this in my RC8.2e and it really doesn't feel like a 4100mah pack. I use Reedy Wolfpack saddles as well and these stack up at around half the price. It is also quite a light 4s pack (due to lower capacity) so if you do use a car with a layout similar to the RC8.2e you might notice a slight difference in handling. Perfect for the bashing enthusiasts out there - not sure how they would stack up for racers.
superb battery especially for the price. Going to order more at a later date!
Bought two of these to run in my RC8.2e and they charge and run fantastic for the price. I have a few $100+ Orion saddle packs and the quality of the product is really no different and for most 35c is plenty. I will definitely be buying more of these in the future and highly recommend them to others who don't need top echelon race spec lipo's.
Absolutely awesome! Dropped one of these in a rc8.2e and loving the weight equality!!!! No more heavy side. This buggy handles fantastic. I'm running a tekin rx8 and a tekin gen 2 1900kv motor and reporting 14 minute run times easy! This is the answer to the rc8.2e. The price is right too. Don't let the 35c rating scare you off they perform as good as anything else on the market. Save your money!!!!!!! Weight bias is everything. If your running 5000 mah packs your too heavy for this buggy. I'm weighing in at 7.8 lbs with this battery. Thanks
this battery is absolutely terrible!!! we've all heard the term you get what you've paid for and its never been more true than in this case. i ran this battery with my mamba monster going at 60% power for about 20 minutes and the connections on the battery melted through causing both connections to stick together resulting in me having to un solder the connection from my esc. after fixing the problem i ran it again the next day to drain the battery. i then connected it to my balancing charger where i then found out the balancer was no longer working. i then tried charging without a balance and just received a low voltage message meaning the battery is completely dead and no its not user flaw i drove with a venom 3 cell for about a year with the same set up and its still kicking to my surprise unlike this eco. so if you drive a little car with absolutely no power in mind it might be ok but on an mbx6e with mamba monster 2 2200kv running only 60% power then you're wasting money. the only reason i bought this is because i first purchased the 6s but after tearing all the tires off the rim i realized it was WAY too much power so i took the chance buying the 4 cell thinking it'd be ok which was stupid of me because i never even drained the 6s its just too much power for bashing in my area. spend the extra $100 on something with some quality if you have a car with any amount of power that you plan on driving more than 20 minutes.
Great battery, running with a 2100 kv 1/8 motor I get no heat issues or puffing. Plenty of run time, I'm buying 2 more.
I've had mine a couple months now. It seems to be a pretty good battery. Despite being 4100mAh and 35C it has plenty of power to make a 7 minute race (I can make nearly 20 min during practice with a 1900kv motor) and more punch than you need. It fits under the body of my TLR 8ight-e 2.0 better than my other batteries (Gens Ace 5000mAh, Venom 5000mAh). I have switched to this almost exclusively because I like the way the car feels with the lighter battery. Weight wise its like putting a shorty pack in a 1/10 scale car compared to a full size. The only thing I don't care for, is the beige insert in the case (where the wires come out) doesn't like staying in place. It likes to pop out. It's not hard to put back, but I am thinking of Shoe Goo'ing it next time. But for the cost I haven't found a better battery for my 1/8 scale buggy.
i just recieved them in the mail today have not run them yet but from just looking at them they look like they are wel constructed and they fit in my rc8.2e
Not a bad battery for the price. Unfortunately after 5 months of ownership and about 15 cycles through each battery, two of them have balance leads that seems to lose connection. Whenever i have them on the balancer, i need to wiggle the balance cable in order for them to function correctly and read the right cell voltage. They otherwise perform great and give my buggy more than enough power.
I have two of these for rc8.2e, they perform perfect, surprisingly long run times, I won't buy anything else..... I used high-end brand 2s lipos for indoor 1/10 scale racing, after 8 months or so with light use, two batteries discharged very uneven and didn't balance well either, so after that I'm not sold on "you get what you pay for"
Love 'em. Big bang for the buck. I'm used to running 100C and these pack alot of punch and easily last 5 minute qualifiers. Light weight and fit is perfect in MBX6e.
So far, 5 race days with no issues. I like the lighter weight, and the slightly smaller physical size in my Tekno RC8. Excellent power. Excellent price. I bought these after puffing two Gens Ace packs in one race day. If these last a season, I'll just buy fresh ones every spring. Thanks Amain!
EDIT: Have a few more race days on these, and they're still working great. Still no issues. I am very surprised given the price.
I just bought two of these for my duratrax dxr8-e. Will have a better write-up after i put them thru the paces!
