Tattu Plus Battery Review

  • News

Tattu batteries are specifically designed for use with multi-rotors, and have gained a reputation for being some of the best and most reliable UAV batteries on the market. We use the standard Tattu batteries on our heavy lifters and have always been very pleased with their performance, so this review will focus on the differences between the standard Tattu batteries and the Plus batteries.

First, let’s talk about the physical changes Tattu made to these batteries.

A. Protective Casing

A new protective casing houses the battery cells, providing extra security against hazards and helping to keep the batteries from getting puffy as many other batteries do over their lifespan.

B. Casing Extension With Indicator System

The new casing also houses the indicator system which provides the battery’s “smart” capabilities. Unfortunately, this does lengthen the battery by inches and increases the weight by a 1/4 lbs. per battery.

C. Longer Power Leads

The last time we reviewed Tattu’s batteries, we mentioned that their power leads were some of the shortest we’d ever seen on ship batteries. Well, Tattu heard this and decided to make their power leads inches longer on this new version. This is great for those of you with ships that have tight wiring, (and those of us who don’t need the extra length can cut the leads down before soldering on our connectors).

D. Removable, Longer Balance Taps

One interesting design feature is removable balance taps. There is now a balance tap port on the bottom of the battery and they have included longer wires individually for those who choose to use them. We highly recommend using voltage alarms on balance taps, so we would never leave the taps off of our ship batteries. Additionally, with the way the batteries fit onto the Alta, the placement of the port is not a problem, but those of you using the batteries in an upright position on your setup may not be able to access the port. It’s also worth noting that the removability of the taps could conceivably reduce the security of using voltage alarms, as the taps could come loose at the base and render the alarms useless. This seems highly unlikely, but it is something to consider.





Smart Features

Now let’s cover the new “intelligent” features of the battery.

A. Battery Charge Status

The most obvious feature is being able to check the charge of the battery by pressing the button and seeing white LEDs indicate the amount of charge in increments of 25%. The battery will also indicate if it is below 8% by having the bottom LED flash instead of staying solid.

B. Battery Warning Status

In addition to showing you the charge percentage, the battery will also warn you if there is anything abnormal with your battery. In these cases, the LEDs will turn red instead of white. The indicator can warn you of problems with temperature, charge amount, and imbalance.

1. Temperature

If the battery reaches an unsafe temperature, two lights will flash red. If it’s too hot, the top two lights will flash. If it’s too cold, the bottom two lights will flash.

2. Charge Amount

If the battery is overcharged, the top LED will flash red. If the battery is undercharged, the bottom LED will flash red.

3. Imbalance

If the battery has a problematic imbalance, both the top and bottom LEDs will turn red.

C. Storage Function

The next helpful feature is the storage function. If you want to store your batteries at an optimal storage charge and don’t have a storage function on your charger, you can use their built-in storage mode. All you have to do is hold down the button for 3 seconds or until the LEDs will finish flashing, and it will go into storage mode. If the charge is too low, the indicator lights will flash white and the battery will not go into storage mode. To exit storage mode, all you have to do is hold the button down again until the top 2 and bottom 2 LEDs finish flashing white alternately.

D. Intelligent Self-Discharge

On a similar note, the batteries can discharge themselves and enter into storage mode automatically if they are left charged for too long or if left charged in dangerously high temperatures.

E. Finally, the firmware on the indicator system can be updated for future upgrades.


In conclusion, let’s cover the pros and the cons the Tattu Plus batteries have compared to their standard Tattu counterparts.

A. Pros

  1. More protection from new casing
  2. Longer leads for more flexibility
  3. Battery status info at your fingertips
  4. Generally pretty simple to remember what indicators mean
  5. Safeguards to protect life of battery
  6. Price – same as non-smart version

B. Cons

  1. Heavier, could max out weight on the Alta
  2. Longer, can’t easily be swapped with other length batteries on the Alta
  3. Balance taps could disconnect at base or could be incompatible with upright battery positions

So who would we recommend these batteries to?  We’d recommend them to both beginners and pros.  Having a durable and reliable LiPo to keep your multi rotor safe in the air is a must.
