Protection Circuit Module for 15 Cells LiFePO4 Battery Pack (Working: 10A) $87.49 Specifications of 4 Series LiFePO4 Batteries Charge & Discharge Guard Shield Application The product could be widely used in the fields of electric devices, electric vehicles, standby power supply and power supply of military equipment, etc.Features Provide protection function and balance function to 15 cells High Power LiFePO4 Battery in series. Over voltage, under voltage, over current, short circuit. Bleeding for cell balance. Low power consumption. Functions:The product has 6 main functionsover charge, over discharge, over current, short circuits, balancing and low-current lock. Function of over charge protectiononce voltage of any battery in the group gets higher than the over charge protection point, charge cuts off to ensure all batteries work within the over charge protection point.Function of over dischargeonce voltage of any battery in the group gets lower than the over charge protection point, discharge cuts off to ensure all batteries work beyond the over charge protection point.Function of over currentduring the discharge process of battery group, once discharge current gets over the set over current protection point, output cuts off to ensure battery group works within the safe limit of current.Function of short circuit protectiononce battery group’s output port appears the condition of short circuit, it cuts off to ensure battery group not to be damaged because of short circuit.Function of voltage balancingin the late charging period of battery group, voltage difference that appears during the using process of each battery could get balancing revised to ensure battery group’s capacitance.Function of low-current lockseries connection of low-current lock gets reserved and low current controls on-and-off of the main high current to make it safer and more convenient.

!Caramba! $13.95 Natalie and Consuelo are like-minded individuals who live in Lava Landing, CA. When they aren’t working at The Big Cheese Plant, they get all dolled up for the racetrack, or go for at a tequila float at The Big Five Four. They urgently need to get Consuelo’s father out of Purgatory: he won’t stop turning up in women’s dreams until they do. But that means a trip to Mexico, and Consuelo still hasn’t gotten over her fear of long car rides . . . . Inspired by La Loter’a, a Mexican game of chance not unlike bingo, the novel is a joyous story of mamacitas and mariachis, fiestas and tupperware parties, rodeos and Miss Magma beauty contests. In Caramba! the American experience emerges in a brilliant new language and landscape, both touching and dazzlingly fresh. |
