Bullspower Technology delivers safe lithium phosphate energy storage solutions in standard lead-acid battery sizes for a wide variety of applications.
12V 16~20Ah Energy Storage Systems are a bullspower of 12V battery modules and accessories. The 12V bullspower is designed as a drop-in replacement for similar sized lead-acid batteries offering twice the run-time and nearly half the weight. The 12V series is designed for lower voltage, lower power and longer run-time applications.They are built with LFP Technology that offers outstanding intrinsic safety and excellent float and cycle life resulting in low cost of ownership.
Features:
1.Built-in automatic protection for over-charge,over-discharge and over-temperature conditions
2.Maintenance free
3.Internal cell balancing
4.Communication of monitored data via Battery Management System (BMS)
5.Thousands of cycles,100% DOD,under normal conditions
6.Can be charged using most standard lead-acid chargers (set for AGM/GEL cells)
7.Flame retardant plastics
Application :
1. Large-scale electric vehicles: electric bus, electric car, E-Tour Car
2. Light electric car: e-bike, e-scooter,e-motorcycle, electric golf cart, e-wheelchair
3. E-tool: electric drill, electric saw, lawn mower and so on
4. Remote control cars, boat, aircraft, toys
5. Solar and wind power generation energy storage devices, Telecom base Station
6. Small medical equipment and portable equipment

Advantages of Bullspower LFP batteries
As a substitute for Lead Acid batteries, LiFePO 4 rechargeable battery is our new product. Some of the main advantages
are as follows:
* Safe technology, will not catch fire or explode when being overcharged, because:
(1).Fast charge capability that avoids lithium plating at the negative electrode;
(2).Dual plate laser-welded aluminum cell construction;
(3).Advanced vent technology to safely release gas pressure buildup;
(4).Center pin construction designed to allow efficient gas release and avoid internal mechanical deformation
under extreme abuse;
(5) .Phosphate does not release oxygen.
* One third the weight of an equivalent lead acid battery;
* Over 2000 deep discharge cycles compared to typically around 300 for lead acid;
* More usable capacity than that of similar amp hour lead acid batteries;
* High discharge rate capability, 10C continuous, 20C pulse discharge;
* Unlike lead acid batteries, can be left in a partially discharged state for extended periods without causing
permanent damage;
* Extremely low self discharge rate, about 1~2% per month;
* Does not suffer from "thermal runaway" .It is be accuse there is a special component called PTC insertion
(Positive temperature Coefficient).When temperature gets too high, PTC refrigerates by augmenting its
resistance, then current steps down until interior temperature gets normal.
* Can be used safely in wide ambient temperatures of -20 to 60 deg.C without any degradation in performance.
* Can be connected in series for higher voltages or parallel for higher capacity.
* Maintenance free;
* Does not contain any toxic heavy metals such as lead, cadmium, nor any corrosive acids or alkalis thus making
LiFePO4 batteries the most environmentally friendly battery chemistry available;
