Waterproof LTO BMS 36V 10S 80A PCB PCBA BMS System With Balance
Common Port For Solar Storage Energy
Overview
This BMS is customized for 3~32S LTO battery pack.
We can design BMS for various lithium batteries like LiFepo4,
LiMn2O4, LTO, and Li-polymer etc.
The main functions are: over charge protection, over discharge
protection, over current protection, short-circuit protection,
temperature protection etc.

Advantages
1. Use top quality (A-level) protective integrated circuit IC, from
the solution of Seiko of Japan.
2. Strong load ability, constant discharge current 80A , use high
voltage resistance, low inner
resistance power Mosfet. The heat sink will greatly help cooling.
3. IC itself has power balancing function. The circuit is simple
and reliable.
4. Typical voltage detection for each cell. So each battery will be
prevented over charged or over discharged. Over current and short
circuit protection
function is very reliable.Long time short circuit of the load won’t
affect the PCB and the battery.Temperature protection during
charging and discharging.
5. Extreme low power consumption.
6. PCB use high anti-corrosion, high water resistance, high
impedance ESD conformal Coating

common Version : common port for charge/discharge
What is the balance function?
The working principle and function are as followings, when your one
cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4 upto
(3.6V), then the cell Balance starts to work, balance resistance
starts discharge with 35ma(when balance discharge starts to work,
BMS will starts a little heat up, which is the normal reflection),
the cell is in both charging and discharging status, and others
which are not reached to alarm voltage(Li-ion 4.18V, Life
Po43.6V)are only in charging status, no discharging, when the fast
cell voltage is reached to alarm voltage (Li-ion 4.25V, Life
Po43.75V)BMS starts off power protection, all the other cells
are all in stop of charging, this process will enable your battery
charging in balance current, and your battery voltage are in
balance status, but when your cell voltage difference are in a big
range, then balance can not be functionning.
