If possible i intend to bottom balance first before charging and using it.
Charging lithium ion batteries with solar panels.
Here i am going to build a 18650 lithium ion battery charger harnessing solar energy.
There are many lithium ion solar batteries on the market.

Charging lithium ion batteries is a tricky affair and too with solar power because lithium ion batteries are dangerous and require controlled charging environments.
This allows charging lead acid to 14 40v 6 x 2 40v cell and li ion to 12 60 3 x 4 20v cell.
It is better then 5v.
As with a regular quality battery charger various battery types are accommodated.
Material links are affilliate.
The tesla powerwall is one of the cheapest lithium ion solar batteries which is one of the reasons it is so popular.
Popular lithium ion solar battery brands.
If you want the panel to charge the battery to fully charged even on a low sun day if necessary then you need a panel that is full load rated at at least 12 6v 90 14v.
Charge controllers are also available for lithium ion to charge 10 8v packs 3 cells in series.
Charging lithium lifepo4 batteries from solar panels.
Note that 2 40v cell for lead acid and 4 20v cell for lithium ion are the full charge voltage thresholds.
So you can choose 500 mah solar cell or 1 ah solar cell.
Solar energy is abundant on earth surface.
12v 60ah lifepo4 battery deep cycle lithium iron phosphate rechargeable battery built in bms protect charging and discharging high performance for golf cart ev rv solar energy storage battery 299 00 299.
The most popular choice for residential energy storage is the tesla powerwall a 13 5 kilowatt hour kwh lithium ion battery that costs about 9 000.
Otherwise it may lead to explosion also.
Again with the faster charge rate that lithium batteries can accept even a 45 amp lithium charger can recharge a 100 ah battery 100 ah divided by a 45 amp charge rate that would equal about 2 2 hours plus the extra time required at the end of the charge due to a lower charge rate would equal an estimated recharge time of approximately 3 hrs.
Lithium ion batteries 18650.
For li ion.
As above as an sla targeted 12v panel makes about 18v at full sun full load such a panel will provide more than enough voltage under all practical light conditions.
