Several charging sources area unit possible:

Alternator: Most alternators (marine, RV, cars) can with efficiency charge BSLBATT® lithium-ion technology as before long generator charge voltage is between fourteen.0V and 14.6V (for a 12V battery)

Conventional lead-acid accumulator charger: Wisdom Power® Battery Management System (BMS) is intended to be compatible with customary chargers. you would like to ascertain that the charger encompasses inherent CC/CV charge algorithmic rule (Constant Current / Constant Voltage) and the charger most voltage is comprised between fourteen.0V and 14.6V (for a 12V battery)

Lithium-Ion charger: this can be the simplest thanks to charging Wisdom Power® Lithium-ion battery. These chargers embed some dedicated charge algorithmic rules with precise charge voltage. It conjointly manages with efficiency charge floating voltage and period so as to maximize battery life.

Q12. Are lithium batteries harmful to the environment?

LiFePO4 batteries are easily recyclable, and since they only need to be replaced about once a decade, you’re cutting down on waste produced. LiFePO4 technology is compatible with solar applications, and you may also choose to buy a battery made from recycled material.

Q13. How long will a BSLBATT® battery last?

BSLBATT® advanced lithium-ion technology can give you 3000 complete charge and discharge cycles at eightieth DoD (Depth of Discharge). once 3000 cycles, you may still have over eightieth of usable energy left. just in case you discharge BSLBATT® at the sixty-fifth DoD rate, you’ll be able to expect to urge 5000 cycles.

Example 1: One BSLBATT® 12V-100Ah battery, once being discharged at eightieth DoD for 3000 cycles, is currently a 12v 80ah battery.

Example 2: One BSLBATT® 12V-100Ah, once being discharged at sixty-fifth DoD for 5000 cycles, is currently conjointly a 12v 80ah battery.

In terms of your time period, If you discharge eightieth of the BSLBATT® and so recharge it on a daily basis, seven days every week for eight years, you may still have eightieth of usable battery energy left. this can be an outsized increase in period of time compared to a traditional Lead Acid battery (AGM, Gel) rated at five hundred cycles for five hundredth DoD cycles.

Q14. Is charging LiFePO4 batteries time-consuming?

LiFePO4 technology offers 100 percent charging efficiency, drastically reducing the amount of time you must wait for your battery to charge. Lead-acid batteries average a charging efficiency of 85 percent. Unlike lead-acid batteries, lithium doesn’t need to go through the time-consuming absorption phase, which provides the final 20 percent of power during charging. Lithium receives a full charge in a fraction of the time.

Q15. How does lithium’s shelf life compare to that of lead-acid?

Unfortunately, lead-acid batteries deteriorate unless you charge them every day. Lithium maintains most of its usable capacity even if you store it without charging for a year. For optimal protection, experts recommend storing LiFePO4 batteries at 50 percent depth of discharge (DOD).

Q16. How much maintenance do LiFePO4 batteries require?

The short answer is virtually none. While lead-acid batteries must go through routine saturating charges lasting 14 hours or longer, LiFePO4 technology maintains consistent power even if you only charge it partially. However, extreme temperatures may damage your battery, and you should take care to charge it at the right voltage. 14.6 V is the recommended charging voltage.

Q17. What is the Battery Management System (BMS) and the way will it work?
