Anyone added a second hybrid battery?

[GPSMan]

The design supports gasoline for acceleration and battery for sailing, gliding, coasting whatever you'd like to call it.

Remember: 22 horsepower is what you get. Not powerful enough to reasonably accelerate, just about right for maintaining speed.

This truck gets 55 to 58 MPG using it in this manner. Sometimes 60+ MPG.
The extra weight of extra batteries will hurt MPG in most cases. Also double the mass to heat up when too cold and double the mass to cool down when hot, and all that spends gasoline.

Without a plug, larger batteries won't help you UNLESS you have this specific case:

3 miles of downhill travel that is steep enough to require regen braking followed by uphill to use that up. Repeat.

If you don't have that repetitive scenario, extra batteries will just hurt your cost. Buy if you are into buying useless accessories for your truck, then knock yourself out, as long as you are not expecting performance gains or higher MPG.

I do this 6 days a week. On Sunday I rest.

Hybrids and BEVs in general are finely tuned parametric systems. You change the battery, you generally need to change the associated software, the charging-discharging systems, the battery heating/cooling systems. Also possibly the suspension and frame (because batteries are really heavy). Also possibly you might need to install higher rated cables to carry additional current.

It's really no different than ICE engines in the general sense. If you put a bigger engine in your old beater just for grins, it's likely to have a short (but probably fun) lifespan or blow up in a spectacular way - unless you upgrade a whole lot of other stuff to handle the extra HP & torque.

None of this says that adding an extra battery is bad or can't be done. It just takes a lot of brainpower and multi-domain engineering expertise. BEV makers do this all the time. You can get yourself a small pack, or a medium pack, or a large pack. One motor or two motors or three motors or four motors. Just like Goldilocks. Whatever your heart desires and your wallet can handle.

Just push the little pedal below your foot further down. Get 5mph faster than posted speed let off the magic peddle and boom...Electric. faster than doing it the snail way.

Not the most efficient way, but that is what I do 90% of the time.

Wouldn't be snail like if it would just allow 15% power before starting the engine.

But at least now you know why it doesn't.

BTW currents are so great at the 9% rate, the battery temperature is going up about 5°F per minute.

Flying cars would blow a two battery Mavericks away.

Cmon man, dream big or go home.

You just learn to use the system to get the most out of it. Using the electric motor to accelerate in anything more than stop and go traffic just isn't what it's designed for. Sure they could give it more power and a bigger battery, but that would increase the cost significantly. Keep in mind the hybrid system was designed to be the base model powertrain for a 19k vehicle. The fact that the electric motor tops out at around 124HP (a member did some dyno testing) is not too shabby, it's just a big vehicle to move with that much power. Crazy to think that is more HP than my first two ICE vehicles.

Pulling away from a stop sign on a side street with no traffic behind you is hard. Half a block to reach 20MPH. If I am on a non-busy residential side street it can be done. Pulling away from a stoplight in Electric only in a 30-35 zone is near impossible without getting pushed out of the way. It does have plenty of power while burning gas though. Maverick was never a $19K vehicle. The early 22's were $21,490 sticker with no options.

Fully aware, I've been here for years. Delivery charge included with the sale price has nothing to do with base vehicle price though, which is what dictates what price point of the vehicle is built to.

I'm fully aware of the speed, I have a 22 Hybrid. Had a hybrid for years before that too. They just don't do what you want. You need a plug-in hybrid for that, since they have more voltage from a much bigger battery to power a bigger electric motor. Just putting a 2.4KW battery (doubling the current one) would not be enough. You need a much bigger, battery.

Ok, so $19,995 is still $20K, not $19K. It just seems to me a little extra battery MIGHT make a difference. The electric motor is using so little of its capability. That's why I asked......

You asked, people answered, you didn't seen like the answer.

I'm just a person who likes to modify and optimize vehicles. I believe it's possible, but just that no one has done it yet, or thinks it's possible. And that's OK. I'll just use the 22HP weed wacker motor for what it is I guess. One day soon there will be shops that build and modify electric/hybrid vehicles. Just not yet.

It's not 22HP, that's what early hybrids had. It's optimized for efficiency not speed.

If you want to modify stuff go for, but you'll need new software and a much larger battery, 10-15KW to get the voltage you want. Possibly a different transmission as well.

The battery is big enough, I can drive for a few miles on the battery just fine, even at 55MPH. It's the way the electric motor is designed, it's not meant to be the primary drive on it's own. This is a hybrid, not a EV or sports car.

I’ve only had my Maverick hybrid for a month and it’s my first hybrid. So I have to ask how do you get your Mav to drive in electric mode at 55 mph?

Read post #5 in this thread. It says the motor is limited to 75 amps, which is 22hp. The motor is much stronger, but limited there at 22.

Must be troll user I've blocked, that post doesn't show. Regardless of what that person said, one user here did a dyno test, it put out way more than 22HP.
