[:en]This is a testimonial/review of the small triangle battery pack and 6 fet 3077 controller. The products and service you provide have exceeded my expectations. After 1,545 miles of riding the small triangle pack with 25R cells is as strong as the day it arrived. It powers my home built mid drive to 32 miles per hour and has a useful range of 30miles when charged and discharged to 90%, I think this is phenomenal for a pack of this size! The 6 fet 3077 controller delivers its 25 amps all day long with extended bursts of 30+ amps and no issues with overheating. Delivery was quick, customer service was excellent and I will defiantly be getting my next battery from em3ev. Thank you[:]

I bought a triangle pack in March 2016…. I reported the issue to EM3ev and they were very concerned. Asked me to do a few tests and it was determined that the battery had a faulty BMS…..
They did a replacement pack with upgraded batteries for free….. I offered to pay USD300 to share in the cost, they refused! I received the new battery 2 weeks after I first reported the issue.
They let me keep the old battery and I was able to salvage about 100 of the cells.
The new battery has been installed for the last month and has already done 700km with no issues.
I would like to commend EM3ev for their professionalism and pride in their company and products.

Excellent, excellent, excellent (did I mention excellent) motor! So much fun, so much torque. I bought mine with 30q 52v battery, unbelievable power. Done about 300 km yet but absolutely no regrets. Get the 42 teeth Lekkie ring, makes worlds of difference. The new color display is also a must item, was going to run the motor without display but now can’t live without it 🙂 Great customer service, will recommend.

Just completed the pipeline challenge 600km of grueling maintenance trail. plenty of sand, rocks pea gravel, some road stages.
Running an 8T MAC in a 29ER with 2x 29E EM3ev triangle ebike battery packs (one borrowed from Kai in review above!) managed 99kms on a single charge using position 1 and plenty of pedaling with avg speeds >33kmh.  Punched it a few times in uphill sand with 2000W+ for ~5mins with no melted anything!
Cant say a bad word about the factory in Shanghai – was looked after like a god whilst Pauls team sorted an issue i had with a bearing.

Things i’ve learned in the 7 ebike kits i’ve bought from Paul (for both my bikes and friends)
no-one has broken anything and price is forgotten on the first ride when you realise that a bike fitted with a MAC and a frame pack = street weapon / commuter / downhill / fatbike / mountain bike whatever you want Paul has a kit to suit.
thumbs up – thanks again Paul and the team at EM3EV
