The AnewPow/ LithiumPower Inc batteries are thoroughly made, with protection and balancing features besides adapting to the Neato charger for NiMh, insuring the longest life as the battery wears over time.
The one problem you can have is their system has a microcontroller, and therefore a "sleep" mode shutting down when not used a long time in storage, to preserve the battery. NiMh batteries self-discharge, unlike Lithium, and can wear out in storage, why some customers receive faulty products (warranty and good vendors needed). If the AnewPow battery does not work when installed, because in "sleep" mode, connecting a 9v battery briefly to each pack separately will wake it up. Instructions for this from the company may not be complete. Note the red battery wire is the positive terminal, black is the negative, ground. The yellow wires are for the passive thermistor temperature sensor, which will read within 5-10K ohms depending on temperature, lower at higher temperatures.
Neato software shuts down at temperatures over about 60C as a fire emergency, like a short circuit fault or something. All the battery packs also contain short circuit protection in the packs, for inappropriate use by customers.
Care must be taken repairing any cables and connectors to leave no bare wires hanging around which could accidentally short as the batteries are very powerful, like a car battery, and cause dangerous sparks and over heating the battery, explosions, Armageddon etc.
