Hello Brothers, If I choose the 72V 50Ah 25kw version. How did you deal with the supra connector on the battery ? The supra pro connector is only capable to manage max 15kw of power. (Max around 200A). Does it come with the Qs8 connector, or some other connector that can handle 300A or more? Do I need to Install a new power harness? What is your take on this? Thanks in advance, Sandy 1 Answer

Hey there! Very good question :) We offer the LB batteries with QS8 as well (product page update is coming but you can already ask for it!). I recommend to go for the QS8 if possible as it allows to get a better efficiency with larger cables and a direct connexion without the circuit breaker. Both the Supra and the QS8 have a limited power output (QS8 is rated 200A continuous). Now continuous doesn't mean much for vehicles as even on long straights, current demand drops as soon as you reach peak torque.

does this battery works with torp tc1000 controller? 1 Answer

Absolutely!

Hello, sorry i have one more question, if i install this battery what do i do with the square connector cable i have on my stock battery? I only see the holes for the power cables but not for the other big square cable. Thanks for response in advance you guys are the best! 1 Answer

Hey there! Yes you're right to highlight this. The "data" cable is only used for the stock battery to send BMS data to the stock controller. Aftermarket controllers don't use it, we don't build a data port. All the BMS information are accessible over bluetooth for real-time consulting. The most useful info the controller needs from the battery is how much there's left, and this it can deduce directly from the voltage, so no additional cable required 👍

What are exactly the differences between 17 and 25 kw max power versions apart from obviously the max power, does it perform at lower temparatures ormis range any different or? I am quite new to this but i am looking to maybe purchase this battery for my street legal lb 1 Answer

The only difference is the max output power due to the use of very high discharge cells. At "normal" power, the range will be the same.

Actually four questions, before I pull the trigger: 1. What kind of guaranty do you offer for the batt? 2. What BT BMS has to be used? iPhone compatible? Link to App Store? 3. What exact rating are the cells? 4. Are the gaps in the batt filled with some kind of gel to avoid damages due to vibration? 2 Answers

Regarding cell rating I meant what type of cell? 50E? 40T? Other?

Thanks for your interest! 1. We offer a 2-year warranty on all of our batteries 2. JBD BMS, best in class BT app on iOS and Android 3. A-grade, bench tested charge and discharge. 4. We use cell holders and fill the case with some vibration dampening foam to make sure it sits tight and the bikes vibrations won't alter its integrity.

Great Battery, but a BUT about the delivery times

This battery is awesome! I've been riding for over a month now, and it has great range, good power, and a high-quality finish. A small downside is the manufacturing and delivery times. It says 'in stock, ready to ship' which isn't the case, and the information isn't always clear. Quentin was quick to respond to emails, the times are long but once you know the times, the quality of the product makes up for it. Don't hesitate for a second!

Absolutely Top-Notch, Just Needs a Little Black Dress!

Awesome product, power and range are incredible (fitted with TC 500 and stock motor)! A world of difference compared to the original battery. I was a little worried about the reinforced plastic top part, but after use it's super solid. The only improvement, in my opinion, is the aesthetics of the metal, which clashes a little with the bike's colors. I haven't gotten around to wrapping it yet, but given the friction, anodized metal might be more appropriate. Bonus points for someone like me who charges it every day – it's a good arm workout, the weight is not negligible!

Reliable and Great Capacity!

Awesome battery, light for the capacity (14.88kg)! The cells don't sag too much and the 15kW is plenty, especially with a 56 or 58 tooth sprocket. I'd love to test 18kW on the track but I'll wait for a new motor as I'm not sure the original one can handle it. – Adri
