Mike also makes terrific battery trays for your batts. in many sizes. He will also do custom tray sizes if you need.
I don't not know much about that Novak system...but seeing as your truck is heavy, be careful what system you put in it. Better to save for the
right system then have to buy 2 systems. A mistake that many of us have made before.
On 4s a great system would be either the cc 2200kv/mmm combo or a Tekin system w/a 2000kv , 2200kv truggy motor.
On 5s then either the 2200kv castle system again or a 1700 tekin system. The 1700 Tekin system would be more efficient on 5s than the 2200kv castle system.
Both systems listed above are great and most members here are running these systems and could help w/set up or questions.
1. MBX-6 T8 1900KV, RX8 ON 4S
2. MBX-5T 1520, MMM ON 5S
3. MBX-5 ONROAD CONVERSION 1515, MMM ON 5S
4. MRX-3 ON ROAD CONVERSION 1512, MMM ON 6S
5. TEN T 2650 T8, MMP ON 3S
