The Molicell is a great cell but has less capacity. 4500mAh vs 5000mAh > 18Ah vs 20Ah > 936Wh vs 1040wh The Samsung 50S has a 35Amp rating x4 = 140Amp max. So 60Amps won't be a problem. The Samsung is cheaper at the moment. (Here anyway) Spaces are very tight and a Molicell is 21.7mm in diameter...

Finished my E23 custom Battery. 52V 1040Wh Possible configurations: Samsung 50E / 50S 21700 48V 960Wh 40Amp BMS 52V 1040Wh 40Amp BMS 52V 1040Wh 60Amp BMS

Yes that was with a phaserunner :) it was difficult to get it smooth. I want to order and try an E56 but first have to finish these two. Just had them ceramic coated.

Much worse on a Fat E23 (chainring is more outward) with 3500W Innotrace. It feels like the rear wheel wants to overtake me :) My titanium Fatbike flexes even more. My alu Seroxat bike 3500W Inno motor. Tons of flex! Put together this Exess carbon frame a couple of weeks ago with 3000W...

Innotrace X1 is great but yes it involves shipping to Germany and back. Maybe you can consider having a new unit shipped from Innotrace? I did the Phaserunner internally Ran it for a year but never got it smooth. Not an easy installation! Very hard to configure! Newer Ultra's (since 2018)...

My battery was only 768Wh and came with a 20A BMS. Same BMS also exists in a 30A version. Maybe yours is a 30A version? Check that first! If you want to upgrade: Cables are 14AWG. They can handle 50+Amps But there is almost no room to put a decent BMS. My BMS measures The only...

A 5 amp charger is fine. Of course it depends on the cells (and BMS) You have a 48V 840Wh battery. 840/48= 17.5Ah The Dengfu battery is 13S5P 17.5/5= 3500mAh cells are used. Most Dengfu battery's I saw use Samsung 35E cells Samsung spec sheet says: For a good cycle life 1 Amp per cell is...

Yes Dangerous! I'm not in the habit of bad-mouthing people or companies. I think GBK is a great company, they deliver fast and have a lot of hard to get M620 parts! I order from them on a regular basis. But when they started offering batteries in 2019 I was curious. And skeptical! The price of...

Bad spotwelding.

Use Self-amalgamating tape! It will keep moist out and bond it all together. So you don't have to remove the motor if you need to change the cable.

You can get a raceface 40T They are great! I run 46T on all my +3000W Innotrace bikes. With a 46T you have a lot less torque on the cassette side. My cassettes last a lot longer. With the Innotrace motor 8 Speed is more then enough. Chains cassettes, deraillers and shifters are cheap in...

Fusion 360. Will take another week or two. Yes 21700 looks better. Samsung 50E's are relatively cheap. (3.75€ @ Nkon) 18650 in 5P max 17.5Ah 21700 in 4P 20Ah Cables run between frame and battery. There is enough room. Yes I might sell some. I make a lot of custom batteries.

No. This barely fits. And I prefer some spacers between cell groups. However you can put 15x18650 cells in the frame. Like that you can make quite a compact 14S5P But for max. capacity the 21700's are the better choice.

Made this Dengfu E06 (same battery as E05) Made a 14S5P. It's a tight fit in the case.

I got some empty cases and experimented. Didn't see any extra space unless you don't use a BMS and modify one of the endcaps. I also wanted 52V and went for 14S5P 21700 but had to make quite some frame modifications which I wouldn't recommend. Now working on a 14S4P 21700 (52V 20Ah 1040Wh)...

Yes I wanted to check if there was space for 70cells so I could make a 52V battery. But there wasn't :( Yours are LGMJ1 3500mAh cells. Great specs for a Std Bafang Ultra or a M500/600

I hear they use Samsung 35E cells 13S5P = 840wh But when I bought mine from Dengfu together with an E23 frame I got this: Samsung 32E Which is only 768Wh It had a tiny 20Amps BMS. Absolutely not suited for My Bafang Ultra. So I complained but they told me there is nothing they could do!! So if...

Battery case

You can also get a Dengfu E04 with E06 rear triangle to make a Shimano EP8000 fatbike :-)

That's a CANBUS motor and yes it will work with a 48V battery. I like GBK, I have ordered from them many times. But their batteries were of poor quality. They may have gotten better now, but I would thoroughly inspect any battery that comes from them. Poor workmanship and dangerous! Yes you...
