You can change to a 2s lipo.. (2cell) at 7.4 volts because the xl5 is rated at 8.4 volts max and the 3 cell batteries are 11.1the mAh and C rating all depends on what you want to do with your rusty.
NiMH batteries don't require a balance lead. As we learnt with the relationship between voltage and cells in the NiMH batteries, LiPos are the same but the voltage for a single LiPo cell is 3.7v (not 1.2v like NiMH batteries) so the voltages available are reduced.
It shouldn't take much more than 1 hour to fully charge.
Unfortunately charging NiMH nickel metal hydride batteries is not as easy to achieve compared to other types of cell or battery. The NiMH cells, like NiCds require charging using a constant current.
If left unused for long periods, they will self discharge and eventually just flat out fail. Eneloops, on the other hand, seem to do much better. Not only do they hold a charge longer, but they do not seem to have the same failure rate of the standard NiMH's.

With these tools, It's actually pretty easy to recover these batteries.
- Connect the main plug of your LiPo battery to your NiMH charger and start charging at the lowest current possible.
- After a minute or two your battery should recover to about 3.3 volts per cell.
RC car batteries can die in a surprisingly short amount of time because the cars engines are constantly powering them at high speed. Most people do not know this, but the engine can actually pull too much power from the battery causing it to drain quickly.
Overcharged LiPo spontaneously explodes. Laptop battery in a thermal runaway is lightly pressed on, making it explode. To use Lipo batteries safely, you must treat them with the same respect you would anything that can store and rapidly release a large amount of chemical and/or electrical energy.
They are made of better quality, and when you go to purchase a battery for your RC car, you often get what you pay for. The same thing that makes them so expensive is the same thing that makes them such good batteries.
Conclusion. As the driver, upgrade the motor, ESC and choose a better RC car lipo battery, are the factors that make your RC car faster. Gens ace&Tattu lipo battery can give you the power and run-time you expect from the all Gens ace lipo batteries.
All Lithium Polymer cells have a nominal voltage of 3.7v per cell. When fully charged a LiPo cell should be 4.2v and when discharged it should never be below 3v. You will notice that LiPo packs are made up of layers of multiple cells.
LiPo batteries are assembled with flat slab-like cells. Most LiPos used in RC cars are 2- or 3-cell configurations. The big number on the battery label (3300, 4000, 5000 etc.) If your battery is rated at 5000mAh, that means it can hold a steady 5-amp load for a full hour.
NiMH self discharge causeThese can broadly be described as an oxygen cycle that occurs at high states of charge, and then ion movement that contributes to the self-discharge over longer periods of time. One important factor in the rate of self-discharge is the temperature at which the cell is held.
BRUSHLESS MOTOR: If you are running a brushless motor, you can use up to a 9 cell NIMH pack (10.8v). Different motors have different limitations on cells and chassis may limit cell lengths.
(It is normal for NiMH batteries to get warm as they become fully charged, especially in a rapid charger). If the NiMH batteries get too hot to handle and stay that way for more than 20 or 30 minutes, then the NiCd charger is most likely overcharging the NiMH batteries and may shorten their life.
The chemicals inside the battery begin to heat up, which causes further degradation of the separator. The battery can eventually hit temperatures of more than 1,000° F. At that point the flammable electrolyte can ignite or even explode when exposed to the oxygen in the air.
Capacity of NiMH batteries is close to that of alkaline batteries. Unlike all alkaline batteries (rechargeable or otherwise), internal resistance is low. This makes them well suited for high current capacity applications. Self-discharge rates are comparable, at least up to six months.
Li-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode. The batteries have a high energy density, no memory effect (other than LFP cells) and low self-discharge.
- Never disassemble Nickel Cadmium batteries. Doing so may cause an internal or external short circuit or result in exposed material or battery reacting chemically with the air. It may also cause heat generation, bursting and fire.
