Yeah I have a 12 slot but it’s one I don’t intend to buy again as I only bought it before xmas ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
These are mostly used in sets of 3 so I’m thinking that I may just number them up in groups and just do C/10 for 12 hours. Ikea Ladda cells do not bothered if I fuck ‘em particularly just as long as they don’t go on fire ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif)
I've got a 4 cell universal charger from Nitecore (Digicharger D4) that does everything from 18650s in any Li chemistry down to NiMH/NiCd in AAA - even takes C cells. Autodetects what it's charging and manages every cell independently (needs manually telling that it's dealing with LiFePO
4 cells). You can manually set it to a low charge rate (300mA) on a cell by cell basis too. Takes mains on a 2 pin IEC C7/C8 or 12V DC on a barrel jack. Displays individual charge state, voltage, charging current, and time on charge. Does CV, CC and dV/dt as appropriate for the chemistry in use.
I've been using it for years with some GP low self discharge NiHM, some of which have been heavily abused as far as over-discharging is concerned and it has performed faultlessly. "It just works
TM." I wouldn't hesitate to recommend the D4 and based on my experience I reckon you'd be safe with anything from this brand. They only go up to 4 slots with the fancy displays, but they have an 8 slot charger sans fancy display with just LED charging/charged indicators.
The one I have:

The 8 cell one:
