Finally found the perfect thread to brag about my third ryde. 
5Kg super stiff no concave deck made of one layer 6mm plywood and god-knows-how-many layers of fiberglass.
Combined with generic 90mm wheels and shitty roads for maximum massochistic bliss in every ride.
The Hydra! Cuz charging bms is for pusseh!
Itās actually a 12s10p pack of 1C 3500mAh 18650 cells. I figured itās safer, albeit tedious, to charge each p individually with TP5100 modules than to use cheap bms.

I keep finding myself flabberghasted at the the fucking lengths people on here will go to avoid using a BMS. Jesus christ theyāre not that bad

Not only are they not bad, theyāre actually rather helpful 
Bonus, they are cheap
Bonus, they are small

Without paying for the wires and connectors you could have gotten a bms for the same price

I guess I phrased it poorly - Itās bad that I didnāt add lots of contact on the wires

Haha. Interesting design choice. So how did the charging procedure work? Can you connect all the TP5100 in series? And doesnāt that severely limit your charging speed?
Can you take a wild guess on how many hoursā¦

I have tried many bms.
Just my luck but all of em, even the expensive ones, tend to overcharge a p or two before triggering the protection.
A smart bms would be perfect. Now it would be great if any of ya can teach me how to hack my 13s smart bms to work with this 12s pack.
Itās a tedious, long, slow, inconvinient and terrebly impractical process of charging. The tradeoff benefits are no-overcharge & always-top-balance.
My rig is pretty much like this ( DIY PROTOTYPE Fast Balance Charger - 1000mA Balance Current (1S-20S 84V) - YouTube ) except that TP5100 is twice the power and I dun connect em in series. It can be safely conected in series tho but decided not to cuz I dun have a good multi pin connector that can efficiently conduct the 2amps output of the TP5100.
As for the charging speed, itās normally slow. I mean charging a 35Ah pack with the 2amps rig is normally slow. Can significantly speedup the process by initially charging the pack up to 49V @ 10amps usin my adjustable power supply then do the last mile with the TP5100 rig.
