Advice on lipos for traxxas summit

Hello

The lipos of my traxxas summit which i haven’t used for a year swell. I’m not sure what happened..

I’m looking for a low cost as I don’t use my traxxas very often

Would you recommend the following ones ?

I read the zees are good but they provide a t connector: https://a.aliexpress.com/\_EvF6kRK
