The celllog 8s are nice in theory but look at all the wires that you will be coming out of your battery pack. For a 12 cell battery pack, you'll have 13 wires going to the celllog. I don't know. Just seems like a headache to me. When I'm going to go on a 35 mile ride that I would really need that? I might break down and buy one if I see someone who has set it up nicely and can convince me that it's not a headache. Just seems like another device to get stolen off your bike.
Morph, you leave the cable harness to the CellLog 8 permanently connected to your individual cells (the Chargery cable and most made by individuals use ring terminals to connect to individual cells). There's nothing painful about using the CellLog. It takes a few seconds to plug it into the harness that remains connected to the batteries.
I only have an 8-cell, 24V battery so one CellLog 8 works for me. The Chargery cable on ebay is quite reasonable $14 with free shipping (you'd spend more for the connector and the specialized crimping tool to crimp wires to it than the complete Chargery wiring harness and the wiring harness is very well made to boot). A nice plus is that if you have an iCharger 1010B or 208B, the Chargery cable is 100 percent compatible. If you don't have an iCharger, cut off the banana plugs on the Chargery cable and wire plugs compatible with your charger.
An audible alarm like that provided by both CellLog 8 models is much better insurance that you're not going to deeply discharge your LIFEPO4s and loose recharging cycles.
