Can I use a different charger to charge a Traxxas battery?

[rockhopper2]

I got a trx4 and I bought a lipo battery for it and when I called the traxxas help hotline to ask them the recommended safety timeout for my battery and they told me not to use a different charger other than the id charger from traxxas. Is this true or can I still run a different charger for the battery?

Hi,

All lipo capable chargers have the possibility to charge all lipo batteries. The charger needs to have compatible connectors for it to work.

Does your battery have a separate balance plug?
as in it has the main connector, and then a secondary connector with several wires that are used for balancing the lipo cells.

I also recommend watching a youtube video on lipo basics and safety.

You will need a balance adaptor to charge Traxxas batteries. I have a Hitec dual charger that balance charges my Traxxas batteries using the adaptor


Hang up and Drive

I literally just realised this solved the problem.

Part # 2938 from traxxas.

Fun fact: lipo's don't EXPLICITLY need to be balance-charged. Same as you don't need a crash helmet to drive a Toyota Corolla to the edge of your driveway, but both will increase safety.

You balance the batteries so you don't over-charge/charge a weak cell. A good battery won't have a weak cell & need virtually no help from the balance circuit. Lately I've been leaving my ISDT charger in fast-charge mode that results in minimal balancing and just set cut-off to 4.15v. That little bit less will result in 30-50% more charges, as well as never charge an individual cell past 4.20v.

I just tried the adaptor and it works great but it looks like 2938x is different than part number 2938 without the x
