I know you are looking at the Enerdel cells, not EIG, but just for a data point in reference to using LiPo charging solutions with NMC:
I've been using a 14s pack of EIG 20Ah NMC cells paralleled with 14s2p of 5Ah Turnigy RC LiPo on CrazyBike2 (and then same packs on Delta Tripper for a short while) for more than a year now (have to dig around in the CB2 thread for the posts discussing that, a few months back or so, I think; time has gotten away from me real bad since the non-ebike-related house fire last April).
I bulk charge both packs in parallel, to 58.2V with the present charger (~4.16V/cell) which I think is a KingPan (KingPower?) 3A or 4A, and have periodically checked balance of each one at various SoC, so far essentially no unbalancing (hundredths of a volt). Since this is about 30Ah total of packs, I rarely run it down anywhere near flat, which is between 35-50 miles of range depending on conditions and speed and if I pedal or not, and if I'm hauling anything.
I also have a 3s 20ah lighting pack of EIG cells, which at one point was run down to 0V by someone that messed wiht my light switches while I was at work. It was recharged very slowly from 0V to about minimum normal LVC, then a bit faster from there to a full charge, and discharge tested ok, and has since been used normally to run my "12V" stuff on the bike just as before. It seems to sag more than it did originally, but still works, with peak power usage typically being 60-65W or so with an LED turn signal, brights on the headlight (car halogen), and LED motorcycle taillight / brakelight, plus brakelight LED bar off some car in a junkyard, all active at once.
For the last few months it has not been used as a lighting pack, since i put a 12V DCDC on the bike instead. I added a 4th cell to it to power my laptop (via the AC adapter input) for long wifi sessions out at hotspots when I was at a temporary apartment, with no internet at the apartment itself. But it still has the 12V tap on there for use with the bike for lighting if needed (the bright/highbeam on the headlight takes too much current for the DC-DC), and to use with my 12V compressor for tire repairs. (the compressor takes far too much current to run off the DC-DC for more than a second).
That pack is charged using a Turnigy Accucel6, usually on bulk charge mode, but sometimes I use balance mode for cases where I have used the 12V part of it for the compressor or headlight, to be sure it's all put back correctly. I've used it both on LiPo mode and LiIo mode, and the only apparent difference is a slightly higher end voltage on the pack that goes away pretty quickly. Doesn't appear to add much in the way of stored energy to it.
I've also got a battery medic that I use to check balance real quick on each pack, though I have not had any need for the balance mode on it for them; just a glorified multi-cell voltmeter so far.
So...if your RC LiPo charging solutions allow for setting the HVC to whatever the cell level your NMC cells are designed for, I don't see a reason not to use them for NMC as well.
I haven't done any systematic testing of capacity vs age vs cycles of my packs, so I don'[t know how it all affects it's lifetime overall. (Actually I started notes about that stuff but it was all lost with the fire and I can't remember any of it well enough to recreate the data, and I have done nothing about data collection since then as it seemed pointless without the starting data).
