HI i want to build a safe lifepo4 48 v 16s 1 p pack to test my motor and start using my xiongda 2 spêed.the controler asks for 15 amp peak and since i might up my motor or add another one in future, i figured out that a 30 amp or 60 amp pack would be futurproof and the cells allow it.
I'have read a lot but still noob, and part of me feel overwelmed with the quantity of decisons i need to take to make a fonctionnal safe lifepo4 pack and all the notions that are needed to understand to make those selections.
Is there somewhere a tutorial that list the parts i need to buy to buy and why for a safe 16s1p headway pack?
or
could someone experienced tell me something like : you should get this low level cutout or alarm ,with this bluetooth, bms(some are rated to fry at xamp some cut at x amp, different features included or not) with this charger(smart if possible but not satiator) charge to 3.4?3.6? and here is how to balance your cells . top of bottom balance ? i dont know do it need to balance just at the begining or it is something that have to be implemented in the pack? is internal resistance and capacity test necessary for those used cells ?you see i have noob questions that are big for me but might be simple for an experienced person. and i wonder if there is somewhere a tested and safe 16s1p design that i could simply copy and that has approval of the community? even bms is debated as if it is needed or not, you see the lack of clarity i am facing Hahaha. Then i would just respect how i am told to charge and rince and go on the adventure of ebike life.
I will buy used cells from hookup battery(i contacted them already and shipping is possible to canada and i am willing to pay what it takes without going crazy to get the right parts. It is just that i feel alone and though that maybe just coping a set up that is safe would be easier .
Am i wishing for the impossible or should i just quit this idea of having a ebike?
i know everyone has their life and limited time etc. I would be willing to pay a amount to receive guidance and explanation in part selections and assembly tips. im serious and recongnise that experience is valuable and patient supervision is what im looking for, how much 100 ? 200$ or art i do in exchange for the help? im more on the safer side so if you have a member name to suggest me that is also not paranoid but almost to suggest let me know.
Additionnal info :
-I intend to not push the cell so that they last longer , like maxing the charge at 90% would be ok for my use.
- i already have a opus bt 3100
the cells
