Best ebike Battery for Consumer not Hobbyist/tinkerer?

[Blueshift]

Hi guys, I know a lot of you are DIY... I take it back; most of you are DIY. I am looking for a battery that is consumer friendly and requires no maintenance. The battery should last as long as it is going to last without having to repack or check voltage or anything. If it fails, i wont touch it, ill send it back or dispose of it. I am looking for something around 36v/15ah. or maybe 48v. So it needs to be super reliable and maintenance free. Just a consumer battery like for a laptop or cell phone. Any Ideas?

Good high quality 18650 packs here with BMSes and chargers.

for what you need I would recommend on your pack:

- Lithium-ion or LiFePo4 chemistry

- Tinned copper wiring

- Strong connectors as Anderson SB50 / Powerpoles, or XT60

- Balancing BMS with a continuous current limit under 2C per cell for lithium-ion, 3C - 5C for LiFePo4 (depending of type)

- 0.33C or less charge rating for lithium-ion, 0.5C or less for LiFePo4


If you choose Lithium-ion chemistry:

- Lithium Nickel Cobalt Aluminium Oxide 18650 cells (NCA)

- Factory new high quality cells (Panasonic, Samsung, LG, Sony) for the same Batch. (all those brands has those data printed on the cover and/or the original factory box)

- Spot welded cells with pure nickel strips (invulnerable to corrosion over the time)

- USA / EU manufacturing (generally speaking)

Just get everything from Luna cycle in California. Buy all the pieces one place. Or maybe you just want 36v 250 watt thing ?
What's your base bike ?
Ebikes aren't totally responsibility free must charge every 2 months ect.

I have em3ev kits/batteries and just ordered some more from Luna Cycles early this week - so I can't recommend them yet as I don't have it in my hands. The em3ev stuff is well made, dummy proof, and fairly priced for high quality, noobie-friendly components. The only downside I can think of is shipping direct from China - but the stuff came quickly and very well packed to survive the trip, as China shipping is known for rougher handling than even the shoddy US shipping carriers. Luna Cycles is US-based and everything is on special sale right now for the web store opening - and the prices are unbeatable. Either way, the name-brand 18650 cell-based packs are in my opinion clear winners in today's market.

When you find an 88.8V 10ah 200A rated one for $275 that will give me 12K+ miles and over 3 years of use let me know. I'll probably be looking for a new one in a year or two.

For those not up to date, Luna Cycle is the new web store run by a VERY highly respected long time member of ES. Definitely a place you can trust with your money. And for now, some really great battery prices!

The LunaCycle prices do look pretty good. But at 36v/20ah im not sure if that would melt my motor controller/DD Hub. I got my mototr and controller from ampedbikes a few years ago. I think the controller was rated at 12ah and I was already running 15ah. I cant seem to find the skematics for what the amped bikes motorcontroller used to be just in case.

As long as the motor and controller are rated at the same voltage as the battery, a larger capacity or higher discharge battery will only put less stress on the battery or give more power over time. This will help the battery last longer given the same discharge profile.
