sags more than you’d think. A123 quickly drop to nominal 3.3v and seem to stay there. It’s kind of weird, voltage doesn’t track state of charge very well. It sags but still stays spanky the whole ride.

Range is as you’d expect. Mine are the older 2300mah cells (got a deal for a box of 100, but nowhere close to QB prices). 227.7wh, about 25wh/mile on this setup, and the last 30% or so is hard to get use out of.

1p of these A123 is a pretty nice match for one motor.

Using the bluetooth smart bms.

Yeah, that’s about what I’d expect out of two parallel groups.
Going to have to try some of these out…

Try Google.

is the main form of contact going to be this thread?

I’m probably going to start a large group pm tomorrow.
I don’t want a dig through this thread for info.
Need to figure out who’s backed out to do their own orders.

$5 Samsung 40T until the 27th.
$3 Samsung 25R until the 25th.

For those experienced in terms of shipping cost etc. Does this group buy make sense now?

For 50X40T battery from 18650batterystore I’ll be paying $265.
With the group buy I’ll be paying 195 + shipping from china + shipping within USA($15)

I don’t think so. It has a discharge of 4.8A continuous for optimal battery life. (9.6 for non optimal but you’ll kill your cells that way). Even with a 10p group, you’re using 48A continuous, which is abysmal for the range that you’re gonna get.

They’re designed for ecigs, not really suitable for eskate in my opinion
