@Halbj613 I can highly recommend this book: https://artofelectronics.net/
1220 pages of light bedside reading :grin:

that would be perfect but for me doubt it would happen

trampa says his vescs are good up till 52v

in 13s that would be 4v a cell

i think within a charger you can set it to 52v in a 12s charger
would that not work?

was about to start reading game of thrones but i guess

You’d need a BMS set to balance just above 4.00V/cell then. Still requires the same change, just a different number. That would extract a tiny bit more range from the pack as well.

It is my opinion that reading fictional material is a waste of time.

where your a proper partier

instead of changing the bms what about maxing out the charger to 52v then it an only balance that high

#15865

It will work great, until it doesn’t.

If you don’t understand what that can cause, then read about why cell balancing is needed in the first place for series counts above 1S.

K thank you
Will look a bit into it find out it’s to complicated and scrap the idea

If the pack is only ver charged to like 80% 52v then wouldn’t the bms just balance all the cells to 80%

#15867

No, it will not. That is the problem.

An active cell balancer will. Not a BMS or a passive “bleed-type” balancer.

So then why not use an active balancer
Separate your 13s packs into a 6s and 7s and then active balance with a imax or something similiar

Then the first time you hit a puddle or it rains, you have water in your balance cables since they’re sticking out naked.

I’ll pass on that.

You can get a silicone cover

Are there any smart bms that allow custom balancing?

#15872

Something like this should be able to, not sure what the ranges are but spec sheet says it’s adjustable.

Would be awesome if that could do it

If it is then 13s5p p42a sounds like a good option

#15874

So do you know if there is anyway to find out whether that would work?

#15875

Check with someone who has the smart BMS :man_shrugging:
