Lithium Iron Phosphate batteries will slowly self-discharge when not in use or whilst in storage. The battery run time drops below 80% of the original run time. The battery charge time increases significantly. If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives to clean the Li-Ion battery.
Output Power Lithium battery pack is not same as lead-acid battery, so for the devices which you connect with the battery pack for charging or discharging, such as inverters, MPPT charger controllers or UPS, please implement pre-settings as recommended settings as below before you launched them.
This product specification applies to lithium iron phosphate battery products provided by our company. The product we provide (and which is described in this manual) complies with the requirements of the IEC62133 standard. Customers who use batteries manufactured or sold by our company must read this user manual carefully before using them.
The battery pack should be packaged with insulating and shock-proof material, and labeled as “fragile,” so as to preclude damage caused by bumps during transportation. The battery pack pole should be oriented upward, and a “THIS WAY UP” label should be applied. Do not store the battery pack upside-down, sideways, etc.
The batteries are not allowed to connected with PWM controller for charging. Special Attention: Due to the built-in protection board of the lithium battery pack is with over-discharge protection function, it is strongly recommended to stop using the load when the battery pack is over-discharged.
So now for the epever, less straight forward. It claims to support lithium but these settings can only be set up from the user parameters in the PC software. I don't know if the "lithium" parameter page settings all even work or what oilengine control is. Float Voltage: 15.6v (3.9) ?? Boost Reconnect 15.2v (3.8) ??
