Default Smallest 36v Charger

I'm going with an on-board charger for my TXT so I can properly set up my LiPo battery conversion. Looking to save space and weight so I was wondering what 36v charger is the smallest and lightest?

Thanks.

Quick Charge standard on-board OB3612 would probably be smallest and lightest. It's 12 amp, 18 lbs and measures 4.5" x 7 x 7.5"

If you contact QC before ordering they can also program the charger for Lithium charge algorithm free of charge.

Seriously looking at this one, but also looking at marine onboard chargers. Problem is most of the 36v ones I find are 3 bank chargers which won't work with the Nissan Leaf Battery configuration.

I also ordered Leaf batteries. Going 48v so I ordered 14. After watching a very educated video from evtv.me on Leaf battery testing I am not going to use a BMS per their recommendation. I will just bottom balance the pack and then purchase a charger with a Lithium charge profile with the end phase constant voltage at 4.2v per cell (58.8v for my 14 modules).

I normally use Quick Charge for their on-board chargers and I learned today they can program the end voltage for whatever I specify in a lithium algorithm. I contacted QC and Ray was VERY helpful.

Just FYI if you didn't buy any charging system yet.

Here's the video. He starts talking about the Leaf battery at 1:24:08

P.S. disregard my PM since you started a thread on this topic.

SC:
I am looking at the Quick Charger chargers and will contact them about using a Lithium Polymer algorithm for charging. I doubt I can return the miniBMS I already bought, but I think I'd still need it to warn me from over discharge which is supposedly very bad for these batteries. I could just not connect the relay for the over voltage cutoff and let the Quick Charger determine that.
