FAQ
Frequently Ask Questions
Currently, the LOSSIGY Corporate Purchase Program ships orders to the US, the CA. Other countries can customize.
To avoid cycle life shortening, it is recommended not to discharge the battery below 50%. And when not in use, we recommend charging it 100% before storing it and recharging it after three months.
The discharge working temperature range is -4°F~131°F (-20°C~55°C) and the charge temperature range is 32°F~113°F (0°C~45°C). Using this battery at a lower or higher temperature than the range will shorten the battery's lifespan.
Hello, Lossigy deep cycle battery has built-in BMS to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. With high temp cutting off prevents charging over 167 °F (75°C) and Low temp cutoff protection when charger and discharger.
1: You can use a lithium iron phosphate charger to charge the battery pack.
2: You can use photovoltaic solar panels to charge the battery through MPPT.
3: You can use the inverter to charge the battery pack(note: the inverter needs a built-in AC to DC charging function).
When you connect the battery in parallel with the power cable, please try to keep the length of the positive and negative cables consistent, keep the bolts tight, and it is best to use a soft connection bar or power cable to connect multiple batteries.
Those Lossigy Power Batteries Deep Cycle enable more than 5000 charge/discharge cycles at 80% DOD (Depth of Discharge) in cyclic applications.
Our battery is capable of 5000+ cycles of perfect charge and discharge, after which the efficiency of the battery will drop to 80% of the factory performance, but it is still very good for your use. If you live a completely off-grid life, calculated at the rate of a full charge and discharge per day, you will be able to use it for more than 5 years.
Yes, for single battery unit, the BMS will perform self balancing for it’s cells when being charged.
Should be fine, maybe even a better replacement since LiFepo4 batteries are safer overall. Just make sure the volts and amps match up with the minimum requirements
