For others considering TS LIFEPO4, you aren't limited to 12V smart chargers. The Chargery cable harness that I ordered for my CellLog 8 were built to charge as well, having banana plugs for use with the iCharger smart chargers. I simply cutoff the banana plugs and crimped on an XLR female plug to use the 24V, 3-stage smart charger that I already have. It works well. My batteries are now out of the silver plastic containers and reconfigured--I will be receiving black starboard tomorrow and building a box to house them that will slide into my Currie rear rack. The XLR plug will enable me to charge without opening the case. Here's a photo you can see the CellLog 8 is plugged in as well as the charger. The CellLog's alarm is fairly loud, given the unit's size. I could easily hear it in another room, but I didn't have any other noise in the environment--no TV or radio going.
