Which Battery for a 350W mid-drive?

[Xander02]

ADVICE NEEDED

Hi my daily commute is a fairly short 16km trip.

I want to know what is the smallest battery I can get away with for my 350W mid-drive motor (15ah TSDZ2 motor)? I have seen a 36v 6.8Ah bottle battery which is a nice compact size but I want to know if this would suffice for my needs? If so what sort of average range do you think i could get? The terrain is fairly flat and I would want to go 15-20mph max. I weight about 100kgs. I may plan to only use the motor one one leg of my commute (8kms).

The other alternative is to get a 36v 10.5ah battery but this is substantially larger and may be far too large for my actual needs.

Any help greatly appreciated

Thanks in advance.

We have a Bix Power battery with a TSDZ2 on a trike.

Not bad for a small battery 36V 8.4 Ah, 5.2 lbs. Good for 40 miles.
