Lithium ion battery advice

Recommended Posts

I have a Dyness BX51100 lithium battery and I would to request some advice on the impact of charging on the battery life.

My solar charge on a sunny day is more than enough to run my house and charge the battery, however on a cloudy day the battery is discharged and charged many times in the day.

What affect will this have on my battery cycles and lifetime?

Any assistance will be greatly appreciated.

There's no problem with continuous charge/discharge on a Li battery as long as you keep the DoD (depth of discharge) < battery recommendations, most batteries are to 80% or 90% depth. 

However you need to make sure the rate (Amps) at which you charging/discharging falls within the specs as well, usually C/2.

If you have a decent battery and inverter the BMS should take care of this and the inverter may also have settings that canbe applied to limit charge/discharge rates.

The cycle count will increase as you use the battery, this is normal. On my pylontechs, if i use 10% per day, after 10 days I get 1 cycle used (+-)...Not sure for other batteries.
