Could be you get what you pay for .
My suggestion with lithiums would be to experiment with a small pack and cheap bms to truly understand how they work and the ins and outs.   You could make a pack out of used cells from recycled laptop battery packs or just buy some new 18650's .  The radio controlled hobby sites sell small lithium packs too already put together but they rely on built in balance of external chargers .

Calb is indeed the choice but there are other good brands check the guys at NAWS forum.

A BMS has it's advantages and disadvantages.
However, if you are thinking of  getting one don't go cheap .
I have said it before if there would ever be a WBsr. Then that would be the answer .
Classics and kids already have all the features for lithium but it needs some hardware addition to corrolate with lithium for lvd hvd and soc

Orion BMS seems to be the choice for brands like iron  edison and based on reviews they are good but you have to purchase a tool to verify connection of the battery to the BMS.This cost either the same or at least half the price of the BMS.
