CHARGING and DISCHARGING LITHIUM ION BATTERIES
All 2018 Models of GoBatery Lithium Ion Batteries work using similar NMC Lithium Battery Cells. They work at 12.6-volts when fully-charged (maximum charge and charge voltage), and they will work until they reach a low voltage of roughly 9-volts (fully-discharged). Fully discharging any modern Lithium Ion battery will not harm them, as long as you discharge below 9v.
• Charge Type - Constant Current Charge at 12.6-volts (other charge rates and types will shorten battery life, possibly damage battery cells, and void all warranties.)
To achieve longest life, in general, for most modern lithium ion batteries, they should be run up and down, within the range between 50% and 80% of their capacity. However, they are designed to be fully charged and discharged with a life expectancy over 2500 times or 10 years, while still retaining greater then 80+ percent of their capacity after that. If used and maintained to recommended specifications, a well engineered NMC lithium ion battery can last several decades.
Lithium Ion Batteries should NOT be used or charged in extreme heat, or extreme cold. This can damage the internal cells, and decrease the overall battery life span (dramatically) and performance. Best to keep any electronics in shaded areas, out of direct sun. Out of any area with moisture, rain, snow and ice. While the battery will work in all of these conditions, long term it will damage them. Lithium batteries work best between 40℉ - 100℉ or (5℃ - 45℃).
• All models come with a 10amp-AC Wall-Charger. This charger will work on any 110v up to 220v wall socket. Divide your models Ampere-Hour Rating (100Ah, 160Ah, 200Ah) by 10amps, to know how many hours it will take completely charge if the battery is fully discharged.
o 100Ah model = 10 hours
o 160Ah model = 16 hours
o 200Ah model = 20 hours
Use these guides for high power solar or gas generator chargers : (must be set to 12.6v charge voltage). If using a programmable charge controller, remember to charge using 12.6v Constant Current Chargers only. Amps and Watts can vary, but voltage should be 12.6v
• Recommended Standard Charge Rate from Terminals = 0.2C at exactly 12.6V
o 100Ah = 20amp
o 160Ah = 32amp
o 200Ah = 40amp
o 320Ah = 64amp
o 400Ah = 80amp
o These rates, or lower rates, will extend the life of your battery or batteries
• Maximum Recommended Charge and Discharge Current 50-amp, per/battery in a Parallel Battery Bank Configuration.
• PARALLEL Batteries; can accept 2x normal charge rate. Three = 3x charge rate. Four = 4x.
• Batteries in Series can handle only 50amp Max Recommended.
• Maximum Recommended Discharge Current 1C (can burst discharge at higher 2C levels).
• There is NO Memory Effect with our lithium-ion batteries, so there is no urgent need to fully-recharge ever, in fact Lithium batteries prefer to live in the 50% - 80% charge range, this will extend battery life longest.
• You may charge with a gas-generator or solar-generator using the terminals or Wall-Charger.
• Can store and ship without charging for up to 3 months, but first charge to 50%, not Full.
• Do not Trickle or Float charge when battery is near or at Full Charge.
• Do not Pulse charge or attempt to Overcharge, it can damage any lithium ion battery.
• Do not Top-Off Charge, Bulk Speed Charge, Over Charge, or use Repair Chargers.
• All Li-ion batteries cannot absorb Overcharge.
• Lithium-ion operates safely within the designated operating voltage; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage.
• Only use 12.6V Constant Current Chargers, made for Lithium Ion Polymer batteries.
• Charge process can be intermittent, and Li-ion does not need saturation like you would with lead acid, SLA, or AMG batteries.
• This offers a major advantage for renewable energy storage such as a solar panel and wind turbine, which cannot always fully charge the battery.
• When fully charged, the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium and compromise the battery. To minimize stress, once at peak charge, cut-off as short as possible.
• Discontinue using charger and/or battery if the battery gets excessively warm. Once cooled, you may reuse, but do not use that charger.
