Enerdrive B-Tec Slimline 12V 300Ah FAQs
1. What does 300Ah actually get me?
Serious long-stay capacity, enough to run a fridge, lighting, water pump, inverter and a diesel heater for days between charges. At 630 x 498 x 176.5mm and around 48kg it's a two-person lift, so plan the mounting position before it arrives.
2. How much can I draw from it at once?
250A continuous, with 450A available as a one-second pulse for inverter start-up surges. That covers most high-draw gear without the BMS backing off mid-brew.
3. What charge current should I use?
60 to 120A is the recommended range, with 150A the short-duration maximum. Charge voltage is 14.2 to 14.6V and float is 13.5 to 13.8V, so set your charger accordingly rather than leaving it on a lead-acid profile.
4. How long will it last?
The cells are rated for 2,500+ cycles at 80% depth of discharge, with a discharge cut-off of 11.2V protecting them from being run flat. A battery management system and Bluetooth monitoring are built in, and it carries a 5 year warranty.
