Guidance on Batteries?

[walkingman57]

Hi Folks,

I'm about ready to place an order for an HT1000. I've seen a lot of posts by people who've upgraded from Frey's standard 48V 21Ah to 50V 17Ah batteries.

Straight calculations would give the nod to the 48V 21 Ah battery which would yield 1008 W*hr capacity vs. 884 W*hr for the 52V battery.

Is there something about motor efficiency that informs output in watt*hours/mile (given identical actual riding conditions such as weight, wind, hills, etc) that makes the 52v the better choice for range?

Thanks in advance!

Steve

I’m not entirely sure, hopefully others will comment. I went with the 48v as I wanted range over speed, as the way I understood it the 52v gave more top end and the 48v was as you say better range . How that all works in the real world I’m not sure though we might hear from someone who has a 48v and a 52v battery and can compare on the same bike . Which in thinking about it, I might actually do ( as I was considering a 2nd battery anyway) I’ll need to find out how much a 52v pack is....

Thanks for the insight Stevieman. Are you riding a Frey?

Not yet, been on order for the last 9 weeks, should ship next week. AM1000, Thats if I can stop hitting them with changes and small extras, lol. I’m UK so another 4 weeks after that before I get my hands on it . Have you ordered yet, or still considering ?

Just found this video by Micah Toll who explains the difference in build and output between 48V & 52V batteries. Thanks Micah!

It appears that you get a bump in power which translates to a bit more speed, along with a bump in range. I think I'll stick with the higher Amp-hour 48V to preserve better range. Honestly, I'm looking for ways to save enough by not chasing upgrades so that I can afford to upgrade the controller after I get the bike in hand.
