12.8V 24Ah Safety E Bike Lithium-Ion Battery For UPS System Lead Acid Battery Replacement
G-TECH POWER Oriented with the Japan technology, the only one Chinese factory own the Japan technology, G-TECH company strongly focus on quality control. By being strictly, we prevent sub-standard products from appearing in the market or high scrap rates during production.
We offer a wide product range to our customers and prospects.
In the VRLA range this includes Security batteries, high-rate batteries for power supplies; Deep-cycle batteries for energy storage; OPzV & OPzS tube batteries, Lithium-Ion battery(LiFePo4 battery)...
WHY LITHIUM-ION?
MORE POWER: lighter than lead-acid and packs more power. Our batteries deliver higher power during cranking, and hold a higher voltage during discharge than a comparably sized lead acid battery. That means a hotter ignition, faster starts, and more watts for your accessories.
LIGHTER WEIGHT: Because the lithium powering G-TECH's Lithium batteries produce more pound-per-pound power than lead-acid, less materials are needed. The result is a lighter battery. In fact, some models are so light they float, making them ideal for racing and marine activities.
FASTER RECHARGING: g-tech's lithium-ion batteries accept charge current up to 5x faster than lead-acid batteries, and in many cases Lithium Pros’ batteries recharge in less than an hour.
LONGER BATTERY LIFE: G-TECH lithium-ion batteries provide over 5x the cycle life at 80% DOD (depth of discharge) compared to standard lead-acid batteries, and easily handles 2,000 cycles.
MORE EFFICIENT: G-TECH batteries are 96% efficient at converting input energy into stored energy versus approximately 75% for lead acid.
SAFE & ECO-FRIENDLY: G-TECH Lithium-ion batteries do not contain toxic materials (lead/acid), or emit harmful gases like standard lead-acid batteries. Also, our batteries use Lithium Iron Phosphate which is the safest form of lithium chemistry.
12.8V 24Ah lithium-ion battery
MODEL:LEP12.8-24
Features:
Long Cycle Life: offers up to 20 times longer cyecle life and five times longer float/calendar life than lead acid battery,
helping to minimized the replancement cost and reduce the total cost of ownership.
Light weight: about 40% of the weight of a comparable lead acid battery . A " drop in" replacement of lead acid batteries.
High power: delivers twice power of lead acid battery, even high discharge rate, while maintaining high energy capacity.
Superior Safety: Lithium-ion phosphate chemistry eliminates the risk of explosion or combustion due to the high impact,
overcharging or short circuit situation.
wide temperature range: -20℃～60℃
increased flexibility: modular design enable deployment of up to four batteries in series and up to ten batteries in parallel.
