Nimh or LifePO4?

Nimh or LifePO4 drop in replacement battery for hybrids

We currently have two drop in replacement battery packs designed for hybrids. One pack which meets vehicle demand while at the same time exceeding OEM specs is our Nickle Metal Hydride based pack. Each cell in the pack runs at a capacity of ~8Ah as compared to most manufacturers 6.5Ah. This battery pack would be warrantied for up to 3 years and have multiple pack options. Our specially designed circuit would allow us to be able to build a pack for almost any car, at any capacity. Our larger packs would have enough capacity to be available in plug-in form alongside being a standard, non-plug in replacement. Due to the shape of the cells we would use, each battery chassis would need to be engineered into a different shape than the original, taking up a different footprint in the back of the car while having a shorter profile. The larger packs would remove the HV pack from it's original position and place it in the trunk or above the spare tire. Our pack would cost considerably less than the OEM replacement while being above spec and having a higher capacity. Above all this pack would have a high build quality, easy serviceability, and a high safety standard. This safety includes the possibly of having a smoke detecting expanding foam satchel that would discharge and snuff out any fires within the battery before they posed a problem. 

LifePO4 is the next pack that we are still currently engineering. LifePO4 batteries have a much longer life than Nimh due to their long cycle life. 5+ years would be the warranty on this drop-in replacement. Each cell would have a capacity of 20-40Ah as compared to the Nimh's 8Ah. Due to the nature of the LifePO4 battery's voltage, there would be close to double the amount of cells in the pack, increasing the capacity even further. Each cell would have it's own surge protector of sorts. The device drains excess current that would otherwise harm the cell while at the same time discharging the cell to the same capacity as the rest in the pack, keeping the entire pack completely balanced. The pack would be plug-in compatible for sure with such a high capacity. Due to the nature of the cells and how the car charges the battery, the battery would only be at full charge after being plugged in. Once amperage has been drained the battery will run at low to mid charge until it's plugged in once more. This keeps the battery from cycling as often as a Nimh would, increasing it's life. There is no chance of these cells losing capacity from memory problems from the low cycling. While the cost of the cells and technology in these cells being higher, we are still able to keep the cost slightly below OEM while exceeding the specs 6+ fold. The pack would use the existing battery chassis, keeping the car nearly stock looking. Our plug-in system would be an external charger that would plug into a battery pigtail to charge the large series from your home 110 outlet. As with our Nimh pack, the LifePO4 pack would have an expandable capacity reaching almost unlimited capacity as would fit in the car. The build quality would be astounding, while the safety would surpass our Nimh because of the safe cell technology.
