When DIY,what should we do?
Exercise caution when working with all electrical equipment, wear
safety glasses,gloves etc when appropriate. Sparks & Flashes can
damage your eyes.
Ensure cells are within operating temperature range prior to use.
Do Not Use if cells are punctured, damaged or leaking.
Provide adequate protection to cells during assembly & use
thereafter.
Dispose of properly to recycling or similar facility.

Safety Advice:
Do not submerge the battery in the water
Do not insert batteries with the (+) and (-) reversed
Do not disassemble,dispose in fire,heat or shot circuit.
Do not expose batteries to sunlight for long time
Do not keep batteries close to children
Do not short circuit the battery in any situation.
Do not discharge the new battery! Please fully charge them at
first.
Do not open the battery safety valve.
Do not violently wrest the screw on the terminal.
Do not mix different brands of battery in one pack
Do not mix different capacity or different conditions batteries
together.
Warm Tips:
Please check all batteries voltage and inner resistance and make
sure they are balanced before DIY.All batteries will be tested
before shipment but you need to test there too.You must have basic
knowledge of electronics and battery assembling.If you know nothing
please learn more before doing assembling. No refund or warranty
for any unprofessional operation.Some of the cells will have small
scratches due to moving or long transportation,but it won’t affect
usage at all.Hope you don’t mind it.

Why we need to top balance LiFePO4 cells before we use them to
build a battery pack ?
We buy some cells whether they are grade A, B or C or they are used
LiFePO4 cells, whether they are the same voltage or not, you still
need to do the initial balance.
What that means is to bring them to the same state of charge. But
using the voltage to determine if they are the same state of
charge, it’s unreliable for the chemistry. This is because there
will be relatively.....fly.....charge and discharge curve. That
means it could be the same voltage with your meters but they can be
slightly off the state of charge watts
It is important to have solid initial balance so that when you do
your first capacity test, you have accurate results. If one of your
cells is too high or too low, it triggers your BMS high or low
voltage in this connect. your capacity results will be off. You’ll
think you’re getting ripped off.
Also if you have balancing problems with the used or new pack, and
you stop active balancer on that pack to compensate for that.
You need to do the initial balance and see if this fix your
problem.
People see one of their cells spiking , they’ll say like “oh, that
seems balancing wrong there ”that’s not how you solve the problem.
You should do the initial balance, then the capacity test and watch
the cells under a large loads, to see if they are initial internal
cell resistance. And if you do have a bad cell, you should probably
sweep it off for a new one.
Also keeping in mind if you connect the cells in parallel, let them
naturally balance over time, they will balance.But it takes weeks
or months depending on what size battery bank you have.
The very initial voltage between them is very small, when it’s in
the high state of charge, this will pass current from each other in
balancing very quickly.
People check balancing of their cells and will say, “Oh, it’s only
off by 0.51volt” These are new cells and they come at the same
voltage. I suggest you connect them to a BMS, it could be OK. It is
technically true that you let the BMS monitor the balance on its
own.
But if you have a very large battery bank, or if you have very
ancient in-cell internal resistance, if you have large loads, or if
you want to balance the capacity, you should do a manual top
balance, no matter why.
