E-bike battery blues

[Hairball]

Imagine having 2 BBSHD builds going and no batteries!
Luna has no batteries... Not the ones I want anyway... 48 or 52 watt and whatever ah I can get.
I have no idea when Luna will get more batteries in.

I ordered a small 52 W 11ah dolphin from EM3ev 8 days ago, and just got a notice today that in a few days my battery and charger will ship from China and I will get a tracking number... Who knows how long it will take after that.

I got this 1 battery because I am short so I need a smaller framed bike... I found a 16" Framed, Minnesota 3 that I can stand over but not sure if the battery I ordered will fit....
So, I ran across this rack battery - https://smile.amazon.com/Joyisi-Ele...2043&sr=8-6&keywords=e-bike+battery+rack&th=1

Would anyone advise against a rack battery on a fat tire bike? ... It may be just temporary till I get my other one... I need 2 anyway
I am not going trail riding, we have beaches here and lots of urban paved trails.

Can't say about rear rack battery on fat tire - or why this is important for fat bike in particular.

Note that Amazon don't tell the WH, and users don't ask ...

You might want to check bmsbattery.com - they have a lot of things, prices comparable to Em3va. Rack battery $200: (Link Removed - No Longer Exists). Shipping from China is probably $60-70.

I mounted a BB0S2 and rack battery on a Diamondback Wildwood two years ago. I think it rides fine. I have read a lot of opinions that it makes the back waggle or whatever. Perhaps coming down a dirt trail at speed. It's around 8 or 9 pounds.

I put an 8 pound dolphin battery on my fatbike for a whole. Then a cradle finally got shipped and I moved itto the downtube. The only tradeoff was having to swing my leg over the pack when mounting the bike.

Edit: this pic shows it in 2WD mode. I didn't have a spot for a second battery, which is why I ordered the battery cradle.

I am not interested in a rack battery per se... I just didn't want to buy out of desperation and have it be a bad decision.

This where I bought my last battery. Very highly rated with the Sondors eBike crowd. https://electrobikeworld.com/

I bought the rack battery from Luna, but they never sold a rack for it. Probably the only regret as I mounted it on top of a regular rack, and lost the rack function.

I've bought two batteries from UnitPackPower out of China in the past 10 months. They arrived in less than a week. I believe the last one was about three days. I would buy another, I suppose.

This is a US reseller of chinese bike parts that has been recommended by forum member TomJ. I believe they might be drop shipped from CHina.

California eBike LLC is now an EM3ev battery reseller. Batteries now have Bluetooth BMS. We've seen too many BMS issues with UPP. And no support from UPP in covering warrantees.
