Night Crawler Battery Help

[BJoe]

So I am in the process of reviving my Nigjt Crawler and will likely be doing the same with my Comp Crawler before long too, but I don’t have a good battery for the LNC and probably will need one for the LCC too. I currently have a 2s 1500mAh E-Flite pack in the LNC and 3s 1300mAh E-Flite pack in the LCC. Problem I’m running o to is that the pack in the LNC isn’t holding a charge for long with the new Spektrum Firma 40a 2n1 ESC/Rx I just put in it and stalls out then does mid climb. The Firma ESC/Rx is an IC3 plug and old Losi Xcelorin ESC is an EC3, but want to maybe go to an outrunner in the LCC, eventually.
What battery options would I have that will work with the IC3 plug that don’t involve changing that plug directly. I would also like to stay in a similar mAh and voltage range for the trucks too.

Thanks

I could be wrong but but I thought that only Spectrum batteries come with ICthree connectors installed.

They do, and the ESC/Rx I bought has one too, but can use a EC3 like my existing batteries do. I just don’t have a charger for the IC style system and an adapter to charge the EC3 batteries with my Traxxas EZ Peak charger, which seems to be working fine.
