14S battery with modular diagnostics

Gizmosis350k · May 25, 2020

Hello guys i wish to make a new triangle pack based on this design

https://endless-sphere.com/forums/viewtopic.php?t=96884

that will have
2x JST-XH for 7s each

these JST will be connect to RC voltage meter AND 7s active balancer

AND typical resistive BMS over the same cables.

Is this feasible or will I fry something?

Technically XH is rated 3A

but can go a bit higher no worries.

Personally I'd run at least two in parallel.

Two active balancers? Or two sets of JST for balancing/monitoring voltage?

I hear the ghost drain on the RC Voltage Meters is very undesirable... I may have to look for a LCD (non-backlit) solution...

Two sets of per-cell leads.

Not using the batt, disconnect everything best cells are 100% isolated

Understood. Is it okay if i keep it as one 14S pack? I don't know if i have the skills to make two 7s ones that will fit in the triangle bag lmao :lol:

14S balance charger is very hard to find these days

Agree but, I'm planning to use active balancer/bms instead of a balance charger (they're too expensive lmao)

=== NEG LEAD TO LOAD

:lowbatt:

8S LED Meter, 8S Active Balancer

50 A SHUNT CONNECTION ALWAYS ON

:lowbatt:

8S LED Meter, 8S Active Balancer

- POS LEAD TO LOAD
