lsv nev lithium batteries

[jatgm1]

hello everyone, im trying to decide between a clubcar villager and a polaris/chrysler gem, however thats not the real issue im trying to get to here. i was wondering if anyone knew of a brand of lithium battery that would work well to power a lsv and is reliable with good customer support and a good warantee. also i would prefer if the battery/batteries was a drop in replacement with built in bms's / a built in bms. being able to use the same charger is a plus but if not including a charger with the package is needed. basicly the question is, what is the best brand of battery or brands of batteries for lsv's / nev's ? someone with experience with a spicific seller would be good, however if not advice is advice and i thank you all the same.

i have already determined i need lifepo4 chemistry, and i want at least 100 amphours for the pack. also the ability to choose between 48 and 72 volt systems is good. a pack that is "drop in ready" would be best. dealing with these things has made me grow tired of pack failure so a reputable person is good. i just want to know what sellers online have good reputations.
