PCM for 25.9V (7S) Li-Ion Battery Battery Pack plus LED Fuel Gauge

Description

Protection Circuit Module (PCM) with Equilibrium Function for 25.9V Battery Pack at 10A limit (#4363)
This protection circuit is specially designed for
25.9V
Li-Ion Battery pack with
10A
discharging rate. Different than normal PCB, it provides
equilibrium
function after battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps Li-Ion cells have longer service life.

Fuel Gauge for PCB of 25.9v Li-Ion Battery Pack (#4482
Features
Apply to PCB/PCM of 7 cells Li-ion / Polymer Li-ion 25.9V battery pack.
No external power is need
Can connect directly to pcb/pcm via special connector on board or connect directly to output of battery pack
5 LEDs display battery pack's voltage.
The voltage listed below is base on battery during discharge
. (The actual voltage might vary for LED 2-4 during charging.)
1 LED Flashing = pack voltage  < 20.4V  (must recharge battery)
1 LED = pack voltage: 20.3-24.6V  (battery need recharging)
2 LED = pack voltage: 24.5-26.1V
3 LED = pack voltage: 26.0-27.1V
4 LED = pack voltage: 26.9-27.9V
5 LED = pack voltage: 27.8V or higher ( battery is fully charge)
